    Before: TATEL and SRINIVASAN, Circuit Judges, and
    WILLIAMS, Senior Circuit Judge.
    Opinion for the Court filed by Circuit Judges TATEL and
    SRINIVASAN.
    Opinion concurring in part and dissenting in part filed by
    Senior Circuit Judge WILLIAMS.
    TATEL and SRINIVASAN, Circuit Judges: For the third
    time in seven years, we confront an effort by the Federal
    Communications Commission to compel internet openness—
    commonly known as net neutrality—the principle that
    broadband providers must treat all internet traffic the same
    8
    regardless of source. In our first decision, Comcast Corp. v.
    FCC, 
    600 F.3d 642
     (D.C. Cir. 2010), we held that the
    Commission had failed to cite any statutory authority that
    would justify its order compelling a broadband provider to
    adhere to certain open internet practices. In response, relying
    on section 706 of the Telecommunications Act of 1996, the
    Commission issued an order imposing transparency, anti-
    blocking, and anti-discrimination requirements on broadband
    providers. In our second opinion, Verizon v. FCC, 
    740 F.3d 623
     (D.C. Cir. 2014), we held that section 706 gives the
    Commission authority to enact open internet rules. We
    nonetheless vacated the anti-blocking and anti-discrimination
    provisions because the Commission had chosen to classify
    broadband service as an information service under the
    Communications Act of 1934, which expressly prohibits the
    Commission from applying common carrier regulations to
    such services. The Commission then promulgated the order at
    issue in this case—the 2015 Open Internet Order—in which it
    reclassified broadband service as a telecommunications
    service, subject to common carrier regulation under Title II of
    the Communications Act. The Commission also exercised its
    statutory authority to forbear from applying many of Title II’s
    provisions to broadband service and promulgated five rules to
    promote internet openness.         Three separate groups of
    petitioners, consisting primarily of broadband providers and
    their associations, challenge the Order, arguing that the
    Commission lacks statutory authority to reclassify broadband
    as a telecommunications service, that even if the Commission
    has such authority its decision was arbitrary and capricious,
    that the Commission impermissibly classified mobile
    broadband as a commercial mobile service, that the
    Commission impermissibly forbore from certain provisions of
    Title II, and that some of the rules violate the First
    Amendment. For the reasons set forth in this opinion, we
    deny the petitions for review.

    I.
    Called “one of the most significant technological
    advancements of the 20th century,” Senate Committee on
    Commerce, Science and Transportation, Report on Online
    Personal Privacy Act, Sen. Rep. No. 107-240, at 7 (2002), the
    internet has four major participants: end users, broadband
    providers, backbone networks, and edge providers. Most end
    users connect to the internet through a broadband provider,
    which delivers high-speed internet access using technologies
    such as cable modem service, digital subscriber line (DSL)
    service, and fiber optics. See In re Protecting and Promoting
    the Open Internet (“2015 Open Internet Order” or “the
    Order”), 30 FCC Rcd. 5601, 5682–83 ¶ 188, 5751 ¶ 346.
    Broadband providers interconnect with backbone networks—
    “long-haul fiber-optic links and high-speed routers capable of
    transmitting vast amounts of data.” Verizon, 740 F.3d at 628
    (citing In re Verizon Communications Inc. and MCI, Inc.
    Applications for Approval of Transfer of Control, 20 FCC
    Rcd. 18,433, 18,493 ¶ 110 (2005)). Edge providers, like
    Netflix, Google, and Amazon, “provide content, services, and
    applications over the Internet.” Id. at 629 (citing In re
    Preserving the Open Internet (“2010 Open Internet Order”),
    25 FCC Rcd. 17,905, 17,910 ¶ 13 (2010)). To bring this all
    together, when an end user wishes to check last night’s
    baseball scores on ESPN.com, his computer sends a signal to
    his broadband provider, which in turn transmits it across the
    backbone to ESPN’s broadband provider, which transmits the
    signal to ESPN’s computer. Having received the signal,
    ESPN’s computer breaks the scores into packets of
    information which travel back across ESPN’s broadband
    provider network to the backbone and then across the end
    user’s broadband provider network to the end user, who will
    then know that the Nats won 5 to 3. In recent years, some
    edge providers, such as Netflix and Google, have begun
    connecting directly to broadband providers’ networks, thus
    10
    avoiding the need to interconnect with the backbone, 2015
    Open Internet Order, 30 FCC Rcd. at 5610 ¶ 30, and some
    broadband providers, such as Comcast and AT&T, have
    begun developing their own backbone networks, id. at 5688
    ¶ 198.
    Proponents of internet openness “worry about the
    relationship between broadband providers and edge
    providers.” Verizon, 740 F.3d at 629. “They fear that
    broadband providers might prevent their end-user subscribers
    from accessing certain edge providers altogether, or might
    degrade the quality of their end-user subscribers’ access to
    certain edge providers, either as a means of favoring their
    own competing content or services or to enable them to
    collect fees from certain edge providers.” Id. Thus, for
    example, “a broadband provider like Comcast might limit its
    end-user subscribers’ ability to access the New York Times
    website if it wanted to spike traffic to its own news website,
    or it might degrade the quality of the connection to a search
    website like Bing if a competitor like Google paid for
    prioritized access.” Id.
    Understanding the issues raised by the Commission’s
    current attempt to achieve internet openness requires
    familiarity with its past efforts to do so, as well as with the
    history of broadband regulation more generally.
    A.
    Much of the structure of the current regulatory scheme
    derives from rules the Commission established in its 1980
    Computer II Order. The Computer II rules distinguished
    between “basic services” and “enhanced services.” Basic
    services, such as telephone service, offered “pure
    transmission capability over a communications path that is
    virtually transparent in terms of its interaction with customer
    11
    supplied information.” In re Amendment of Section 64.702
    of the Commission’s Rules and Regulations (“Computer II”),
    77 F.C.C. 2d 384, 420 ¶ 96 (1980). Enhanced services
    consisted of “any offering over the telecommunications
    network which is more than a basic transmission service,” for
    example, one in which “computer processing applications are
    used to act on the content, code, protocol, and other aspects of
    the subscriber’s information,” such as voicemail. Id. at 420
    ¶ 97. The rules subjected basic services, but not enhanced
    services, to common carrier treatment under Title II of the
    Communications Act. Id. at 387 ¶¶ 5–7. Among other things,
    Title II requires that carriers “furnish . . . communication
    service upon reasonable request,” 
    47 U.S.C. § 201
    (a), engage
    in no “unjust or unreasonable discrimination in charges,
    practices, classifications, regulations, facilities, or services,”
    
    id.
     § 202(a), and charge “just and reasonable” rates, id.
    § 201(b).
    The Computer II rules also recognized a third category of
    services, “adjunct-to-basic” services: enhanced services, such
    as “speed dialing, call forwarding, [and] computer-provided
    directory assistance,” that facilitated use of a basic service.
    See In re Implementation of the Non-Accounting Safeguards
    (“Non-Accounting Safeguards Order”), 11 FCC Rcd. 21,905,
    21,958 ¶ 107 n.245 (1996).           Although adjunct-to-basic
    services fell within the definition of enhanced services, the
    Commission nonetheless treated them as basic because of
    their role in facilitating basic services. See Computer II, 77
    F.C.C. 2d at 421 ¶ 98 (explaining that the Commission would
    not treat as an enhanced service those services used to
    “facilitate [consumers’] use of traditional telephone
    services”).
    Fifteen years later, Congress, borrowing heavily from the
    Computer II framework, enacted the Telecommunications Act
    12
    of 1996, which amended the Communications Act. The
    Telecommunications Act subjects a “telecommunications
    service,” the successor to basic service, to common carrier
    regulation under Title II.         
    47 U.S.C. § 153
    (51) (“A
    telecommunications carrier shall be treated as a common
    carrier under [the Communications Act] only to the extent
    that it is engaged in providing telecommunications
    services.”). By contrast, an “information service,” the
    successor to an enhanced service, is not subject to Title II.
    The Telecommunications Act defines a “telecommunications
    service” as “the offering of telecommunications for a fee
    directly to the public, or to such classes of users as to be
    effectively available directly to the public, regardless of the
    facilities used.” 
    Id.
     § 153(53). It defines telecommunications
    as “the transmission, between or among points specified by
    the user, of information of the user’s choosing without change
    in the form or content of the information as sent and
    received.” Id. § 153(50). An information service is an
    “offering of a capability for generating, acquiring, storing,
    transforming, processing, retrieving, utilizing, or making
    available information via telecommunications.”               Id.
    § 153(24). The appropriate regulatory treatment therefore
    turns on what services a provider offers to the public: if it
    offers telecommunications, that service is subject to Title II
    regulation.
    Tracking the Commission’s approach to adjunct-to-basic
    services, Congress also effectively created a third category for
    information     services    that    facilitate    use    of    a
    telecommunications service.        The “telecommunications
    management exception” exempts from information service
    treatment—and thus treats as a telecommunications service—
    “any use [of an information service] for the management,
    control, or operation of a telecommunications system or the
    management of a telecommunications service.” Id.
    13
    The Commission first applied this statutory framework to
    broadband in 1998 when it classified a portion of DSL
    service—broadband internet service furnished over telephone
    lines—as a telecommunications service.             See In re
    Deployment of Wireline Services Offering Advanced
    Telecommunications Capability (“Advanced Services
    Order”), 13 FCC Rcd. 24,012, 24,014 ¶ 3, 24,029–30 ¶¶ 35–
    36 (1998). According to the Commission, the transmission
    component of DSL—the phone lines that carried the
    information—was a telecommunications service. Id. at
    24,029–30 ¶¶ 35–36. The Commission classified the internet
    access delivered via the phone lines, however, as a separate
    offering of an information service. Id. at 24,030 ¶ 36. DSL
    providers that supplied the phone lines and the internet access
    therefore offered both a telecommunications service and an
    information service.
    Four years later, the Commission took a different
    approach when it classified cable modem service—broadband
    service provided over cable lines—as solely an information
    service. In re Inquiry Concerning High-Speed Access to the
    Internet over Cable and Other Facilities (“Cable Broadband
    Order”), 17 FCC Rcd. 4798, 4823 ¶¶ 39–40 (2002). In its
    2002 Cable Broadband Order, the Commission acknowledged
    that when providing the information service component of
    broadband—which, according to the Commission, consisted
    of several distinct applications, including email and online
    newsgroups, id. at 4822–23 ¶ 38—cable broadband providers
    transmit information and thus use telecommunications. In the
    Commission’s view, however, the transmission functioned as
    a component of a “single, integrated information service,”
    rather than as a standalone offering. Id. at 4823 ¶ 38. The
    Commission therefore classified them together as an
    information service. Id. at 4822–23 ¶¶ 38–40.
    14
    The Supreme Court upheld the Commission’s
    classification of cable modem service in National Cable &
    Telecommunications Ass’n v. Brand X Internet Services, 
    545 U.S. 967
    , 986 (2005). Applying the principles of statutory
    interpretation established in Chevron U.S.A. Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
     (1984), the
    Court explained that the key statutory term “offering” in the
    definition of “telecommunications service” is ambiguous.
    Brand X, 
    545 U.S. at 989
    . What a company offers, the Court
    reasoned, can refer to either the “single, finished product” or
    the product’s individual components. 
    Id. at 991
    . According
    to the Court, resolving that question in the context of
    broadband service requires the Commission to determine
    whether the information service and the telecommunications
    components “are functionally integrated . . . or functionally
    separate.” 
    Id.
     That question “turns not on the language of
    [the Communications Act], but on the factual particulars of
    how Internet technology works and how it is provided,
    questions Chevron leaves to the Commission to resolve in the
    first instance.” 
    Id.
     Examining the classification at Chevron’s
    second step—reasonableness—the Court deferred to the
    Commission’s finding that “the high-speed transmission used
    to provide [the information service] is a functionally
    integrated component of that service,” 
    id. at 998
    , and upheld
    the order, 
    id. at 1003
    . Three Justices dissented, arguing that
    cable broadband providers offered telecommunications in the
    form of the “physical connection” between their computers
    and end users’ computers. See 
    id. at 1009
     (Scalia, J.,
    dissenting).
    Following Brand X, the Commission classified other
    types of broadband service, such as DSL and mobile
    broadband service, as integrated offerings of information
    services without a standalone offering of telecommunications.
    See, e.g., In re Appropriate Regulatory Treatment for
    15
    Broadband Access to the Internet over Wireless Networks
    (“2007 Wireless Order”), 22 FCC Rcd. 5901, 5901–02 ¶ 1
    (2007) (mobile broadband); In re Appropriate Framework for
    Broadband Access to the Internet over Wireline Facilities
    (“2005 Wireline Broadband Order”), 20 FCC Rcd. 14,853,
    14,863–64 ¶ 14 (2005) (DSL).
    B.
    Although the Commission’s classification decisions
    spared broadband providers from Title II common carrier
    obligations, the Commission made clear that it would
    nonetheless seek to preserve principles of internet openness.
    In the 2005 Wireline Broadband Order, which classified DSL
    as an integrated information service, the Commission
    announced that should it “see evidence that providers of
    telecommunications for Internet access or IP-enabled services
    are violating these principles,” it would “not hesitate to take
    action to address that conduct.” 2005 Wireline Broadband
    Order, 20 FCC Rcd. at 14,904 ¶ 96. Simultaneously, the
    Commission issued a policy statement signaling its intention
    to “preserve and promote the open and interconnected nature
    of the public Internet.” In re Appropriate Framework for
    Broadband Access to the Internet over Wireline Facilities, 20
    FCC Rcd. 14,986, 14,988 ¶ 4 (2005).
    In 2007, the Commission found reason to act when
    Comcast customers accused the company of interfering with
    their ability to access certain applications. Comcast, 
    600 F.3d at 644
    . Because Comcast voluntarily adopted new practices
    to address the customers’ concerns, the Commission “simply
    ordered [Comcast] to make a set of disclosures describing the
    details of its new approach and the company’s progress
    toward implementing it.” 
    Id. at 645
    . As authority for that
    order, the Commission cited its section 4(i) “ancillary
    jurisdiction.” 
    47 U.S.C. § 154
    (i) (“The Commission may
    16
    perform any and all acts, make such rules and regulations, and
    issue such orders, not inconsistent with this chapter, as may
    be necessary in the execution of its functions.”); In re Formal
    Complaint of Free Press and Public Knowledge Against
    Comcast Corp. for Secretly Degrading Peer-to-Peer
    Applications, 23 FCC Rcd. 13,028, 13,034–41 ¶¶ 14–22
    (2008). In Comcast, we vacated that order because the
    Commission had failed to identify any grant of statutory
    authority to which the order was reasonably ancillary. 
    600 F.3d at 644
    .
    C.
    Following Comcast, the Commission issued a notice of
    inquiry, seeking comment on whether it should reclassify
    broadband as a telecommunications service. See In re
    Framework for Broadband Internet Service, 25 FCC Rcd.
    7866, 7867 ¶ 2 (2010). Rather than reclassify broadband,
    however, the Commission adopted the 2010 Open Internet
    Order. See 25 FCC Rcd. 17,905. In that order, the
    Commission promulgated three rules: (1) a transparency rule,
    which required broadband providers to “disclose the network
    management practices, performance characteristics, and terms
    and conditions of their broadband services”; (2) an anti-
    blocking rule, which prohibited broadband providers from
    “block[ing] lawful content, applications, services, or non-
    harmful devices”; and (3) an anti-discrimination rule, which
    established that broadband providers “may not unreasonably
    discriminate in transmitting lawful network traffic.” Id. at
    17,906 ¶ 1. The transparency rule applied to both “fixed”
    broadband, the service a consumer uses on her laptop when
    she is at home, and “mobile” broadband, the service a
    consumer uses on her iPhone when she is riding the bus to
    work. Id. The anti-blocking rule applied in full only to fixed
    broadband, but the order prohibited mobile broadband
    providers from “block[ing] lawful websites, or block[ing]
    17
    applications that compete with their voice or video telephony
    services.” Id. The anti-discrimination rule applied only to
    fixed broadband. Id. According to the Commission, mobile
    broadband warranted different treatment because, among
    other things, “the mobile ecosystem is experiencing very
    rapid innovation and change,” id. at 17,956 ¶ 94, and “most
    consumers have more choices for mobile broadband than for
    fixed,” id. at 17,957 ¶ 95. In support of its rules, the
    Commission relied primarily on section 706 of the
    Telecommunications Act, which requires that the
    Commission “encourage the deployment on a reasonable and
    timely basis of advanced telecommunications capability to all
    Americans,” 
    47 U.S.C. § 1302
    (a). 25 FCC Rcd. at 17,968–72
    ¶¶ 117–23.
    In Verizon, we upheld the Commission’s conclusion that
    section 706 provides it authority to promulgate open internet
    rules. According to the Commission, such rules encourage
    broadband deployment because they “preserve and facilitate
    the ‘virtuous circle’ of innovation that has driven the
    explosive growth of the Internet.” Verizon, 740 F.3d at 628.
    Under the Commission’s “virtuous circle” theory, “Internet
    openness . . . spurs investment and development by edge
    providers, which leads to increased end-user demand for
    broadband access, which leads to increased investment in
    broadband network infrastructure and technologies, which in
    turns leads to further innovation and development by edge
    providers.” Id. at 634. Reviewing the record, we concluded
    that the Commission’s “finding that Internet openness
    fosters . . . edge-provider innovation . . . was . . . reasonable
    and grounded in substantial evidence” and that the
    Commission had “more than adequately supported and
    explained its conclusion that edge-provider innovation leads
    to the expansion and improvement of broadband
    infrastructure.” Id. at 644.
    18
    We also determined that the Commission had
    “adequately supported and explained its conclusion that,
    absent rules such as those set forth in the [2010 Open Internet
    Order], broadband providers represent[ed] a threat to Internet
    openness and could act in ways that would ultimately inhibit
    the speed and extent of future broadband deployment.” Id. at
    645. For example, the Commission noted that “broadband
    providers like AT & T and Time Warner have acknowledged
    that online video aggregators such as Netflix and Hulu
    compete directly with their own core video subscription
    service,” id. (internal quotation marks omitted), and that, even
    absent direct competition, “[b]roadband providers . . . have
    powerful incentives to accept fees from edge providers, either
    in return for excluding their competitors or for granting them
    prioritized access to end users,” id. at 645–46. Importantly,
    moreover, the Commission found that “broadband providers
    have the technical . . . ability to impose such restrictions,”
    noting that there was “little dispute that broadband providers
    have the technological ability to distinguish between and
    discriminate against certain types of Internet traffic.” Id. at
    646. The Commission also “convincingly detailed how
    broadband providers’ [gatekeeper] position in the market
    gives them the economic power to restrict edge-provider
    traffic and charge for the services they furnish edge
    providers.” Id. Although the providers’ gatekeeper position
    would have brought them little benefit if end users could have
    easily switched providers, “we [saw] no basis for questioning
    the Commission’s conclusion that end users [were] unlikely to
    react in this fashion.”              Id.     The Commission
    “detailed . . . thoroughly . . . the costs of switching,” and
    found that “many end users may have no option to switch, or
    at least face very limited options.” Id. at 647.
    Finally, we explained that although some record evidence
    supported Verizon’s insistence that the order would have a
    19
    detrimental effect on broadband deployment, other record
    evidence suggested the opposite. Id. at 649. The case was
    thus one where “‘the available data do[] not settle a regulatory
    issue and the agency must then exercise its judgment in
    moving from the facts and probabilities on the record to a
    policy conclusion.’” Id. (alteration in original) (quoting
    Motor Vehicle Manufacturers Ass’n v. State Farm Mutual
    Automobile Insurance Co., 
    463 U.S. 29
    , 52 (1983)). The
    Commission, we concluded, had “offered ‘a rational
    connection between the facts found and the choice made.’”
    
    Id.
     (quoting State Farm, 
    463 U.S. at 52
    ).
    We nonetheless vacated the anti-blocking and anti-
    discrimination rules because they unlawfully subjected
    broadband providers to per se common carrier treatment. Id.
    at 655, 658–59. As we explained, the Communications Act
    provides that “[a] telecommunications carrier shall be treated
    as a common carrier . . . only to the extent that it is engaged in
    providing telecommunications services.” Id. at 650 (quoting
    
    47 U.S.C. § 153
    (51)). The Commission, however, had
    classified broadband not as a telecommunications service, but
    rather as an information service, exempt from common carrier
    regulation.     
    Id.
       Because the anti-blocking and anti-
    discrimination rules required broadband providers to offer
    service indiscriminately—the common law test for a per se
    common carrier obligation—they ran afoul of the
    Communications Act. See 
    id.
     at 651–52, 655, 658–59. We
    upheld the transparency rule, however, because it imposed no
    per se common carrier obligations on broadband providers.
    
    Id. at 659
    .
    D.
    A few months after our decision in Verizon, the
    Commission issued a notice of proposed rulemaking to “find
    the best approach to protecting and promoting Internet
    20
    openness.” In re Protecting and Promoting the Open Internet
    (“NPRM”), 29 FCC Rcd. 5561, 5563 ¶ 4 (2014). After
    receiving nearly four million comments, the Commission
    promulgated the order at issue in this case, the 2015 Open
    Internet Order. 30 FCC Rcd. at 5624 ¶ 74.
    The Order consists of three components. First, the
    Commission reclassified both fixed and mobile “broadband
    Internet access service” as telecommunications services. 
    Id.
    at 5743–44 ¶ 331.          For purposes of the Order, the
    Commission defined “broadband Internet access service” as
    “a mass-market retail service by wire or radio that provides
    the capability to transmit data to and receive data from all or
    substantially all Internet endpoints, including any capabilities
    that are incidental to and enable the operation of the
    communications service, but excluding dial-up Internet access
    service.” 
    Id.
     at 5745–46 ¶ 336 (footnote omitted). Because
    the Commission concluded that the telecommunications
    service offered to end users necessarily includes the
    arrangements that broadband providers make with other
    networks to exchange traffic—commonly referred to as
    “interconnection        arrangements”—the          Commission
    determined that Title II would apply to those arrangements as
    well. 
    Id.
     at 5686 ¶ 195. The Commission also reclassified
    mobile broadband service, which it had previously deemed a
    “private mobile service,” exempt from common carrier
    regulation, as a “commercial mobile service,” subject to such
    regulation. 
    Id.
     at 5778 ¶ 388.
    In the Order’s second component, the Commission
    carried out its statutory mandate to forbear “from applying
    any regulation or any provision” of the Communications Act
    if it determines that the provision is unnecessary to ensure just
    and reasonable service or protect consumers and determines
    that forbearance is “consistent with the public interest.” 47
    
    21 U.S.C. § 160
    (a). Specifically, the Commission forbore from
    applying certain Title II provisions to broadband service,
    including section 251’s mandatory unbundling requirements.
    2015 Open Internet Order, 30 FCC Rcd. at 5804–05 ¶ 434,
    5849–51 ¶ 513.
    In the third portion of the Order, the Commission
    promulgated five open internet rules, which it applied to both
    fixed and mobile broadband service. The first three of the
    Commission’s rules, which it called “bright-line rules,” ban
    blocking, throttling, and paid prioritization. 
    Id.
     at 5647 ¶ 110.
    The anti-blocking and anti-throttling rules prohibit broadband
    providers from blocking “lawful content, applications,
    services, or non-harmful devices” or throttling—degrading or
    impairing—access to the same. 
    Id.
     at 5648 ¶ 112, 5651 ¶ 119.
    The anti-paid-prioritization rule bars broadband providers
    from “favor[ing] some traffic over other traffic . . . either (a)
    in exchange for consideration (monetary or otherwise) from a
    third party, or (b) to benefit an affiliated entity.” 
    Id.
     at 5653
    ¶ 125. The fourth rule, known as the “General Conduct
    Rule,” prohibits broadband providers from “unreasonably
    interfer[ing] with or unreasonably disadvantag[ing] (i) end
    users’ ability to select, access, and use broadband Internet
    access service or the lawful Internet content, applications,
    services, or devices of their choice, or (ii) edge providers’
    ability to make lawful content, applications, services, or
    devices available to end users.” 
    Id.
     at 5660 ¶ 136. The
    Commission set forth a nonexhaustive list of factors to guide
    its application of the General Conduct Rule, which we discuss
    at greater length below. See 
    id.
     at 5661–64 ¶¶ 138–45.
    Finally, the Commission adopted an enhanced transparency
    rule, which builds upon the transparency rule that it
    promulgated in its 2010 Open Internet Order and that we
    sustained in Verizon. 
    Id.
     at 5669–82 ¶¶ 154–85.
    22
    Several groups of petitioners now challenge the Order:
    US Telecom Association, an association of service providers,
    along with several other providers and associations; Full
    Service Network, a service provider, joined by other such
    providers; and Alamo Broadband Inc., a service provider,
    joined by an edge provider, Daniel Berninger. TechFreedom,
    a think tank devoted to technology issues, along with a
    service provider and several individual investors and
    entrepreneurs, has intervened on the side of petitioners US
    Telecom and Alamo. Cogent, a service provider, joined by
    several edge providers, users, and organizations, has
    intervened on the side of the Commission.
    In part II, we address petitioners’ arguments that the
    Commission has no statutory authority to reclassify
    broadband as a telecommunications service and that, even if it
    possesses such authority, it acted arbitrarily and capriciously.
    In part III, we address challenges to the Commission’s
    regulation of interconnection arrangements under Title II. In
    part IV, we consider arguments that the Commission lacks
    statutory authority to classify mobile broadband service as a
    “commercial mobile service” and that, in any event, its
    decision to do so was arbitrary and capricious. In part V, we
    assess the contention that the Commission impermissibly
    forbore from certain provisions of Title II. In part VI, we
    consider challenges to the open internet rules. And finally, in
    part VII, we evaluate the claim that some of the open internet
    rules run afoul of the First Amendment.
    Before addressing these issues, we think it important to
    emphasize two fundamental principles governing our
    responsibility as a reviewing court. First, our “role in
    reviewing agency regulations . . . is a limited one.” Ass’n of
    American Railroads v. Interstate Commerce Commission, 
    978 F.2d 737
    , 740 (D.C. Cir. 1992). Our job is to ensure that an
    23
    agency has acted “within the limits of [Congress’s]
    delegation” of authority, Chevron, 
    467 U.S. at 865
    , and that
    its action is not “arbitrary, capricious, an abuse of discretion,
    or otherwise not in accordance with law,” 
    5 U.S.C. § 706
    (2)(A). Critically, we do not “inquire as to whether the
    agency’s decision is wise as a policy matter; indeed, we are
    forbidden from substituting our judgment for that of the
    agency.” Ass’n of American Railroads, 
    978 F.2d at 740
    (alteration and internal quotation marks omitted). Nor do we
    inquire whether “some or many economists would disapprove
    of the [agency’s] approach” because “we do not sit as a panel
    of referees on a professional economics journal, but as a panel
    of generalist judges obliged to defer to a reasonable judgment
    by an agency acting pursuant to congressionally delegated
    authority.” City of Los Angeles v. U.S. Department of
    Transportation, 
    165 F.3d 972
    , 978 (D.C. Cir. 1999). Second,
    we “sit to resolve only legal questions presented and argued
    by the parties.” In re Cheney, 
    334 F.3d 1096
    , 1108 (D.C. Cir.
    2003), vacated and remanded on other grounds sub nom.
    Cheney v. U.S. District Court for the District of Columbia,
    
    542 U.S. 367
     (2004); see also, e.g., United Parcel Service,
    Inc. v. Mitchell, 
    451 U.S. 56
    , 61 n.2 (1981) (“We decline to
    consider this argument since it was not raised by either of the
    parties here or below.”). “It is not our duty” to consider
    “novel arguments a [party] could have made but did not.”
    United States v. Laureys, 
    653 F.3d 27
    , 32 (D.C. Cir. 2011).
    “The premise of our adversarial system is that appellate courts
    do not sit as self-directed boards of legal inquiry and research,
    but essentially as arbiters of legal questions presented and
    argued by the parties before them.” Carducci v. Regan, 
    714 F.2d 171
    , 177 (D.C. Cir. 1983). Departing from this rule
    would “deprive us in substantial measure of that assistance of
    counsel which the system assumes—a deficiency that we can
    perhaps supply by other means, but not without altering the
    character of our institution.” 
    Id.
     With these two critical
    24
    principles in mind, we turn to the first issue in this case—the
    Commission’s reclassification of broadband as a
    “telecommunications service.”
    II.
    In the Open Internet Order, the Commission determined
    that broadband service satisfies the statutory definition of a
    telecommunications       service:       “the     offering   of
    telecommunications for a fee directly to the public.” 
    47 U.S.C. § 153
    (53).       In accordance with Brand X, the
    Commission arrived at this conclusion by examining
    consumer perception of what broadband providers offer.
    2015 Open Internet Order, 30 FCC Rcd. at 5750 ¶ 342. In
    Brand X, the Supreme Court held that it was “consistent with
    the statute’s terms” for the Commission to take into account
    “the end user’s perspective” in classifying a service as
    “information” or “telecommunications.” 
    545 U.S. at 993
    .
    Specifically, the Court held that the Commission had
    reasonably concluded that a provider supplies a
    telecommunications service when it makes a “‘stand-alone’
    offering of telecommunications, i.e., an offered service that,
    from the user’s perspective, transmits messages unadulterated
    by computer processing.” 
    Id. at 989
    . In the Order, the
    Commission concluded that consumers perceive broadband
    service both as a standalone offering and as providing
    telecommunications. See 2015 Open Internet Order, 30 FCC
    Rcd. at 5765 ¶ 365. These conclusions about consumer
    perception find extensive support in the record and together
    justify the Commission’s decision to reclassify broadband as a
    telecommunications service.
    With respect to its first conclusion—that consumers
    perceive broadband as a standalone offering—the
    Commission explained that broadband providers offer two
    separate types of services: “a broadband Internet access
    25
    service,” 
    id.
     at 5750 ¶ 341, which provides “the ability to
    transmit data to and from Internet endpoints,” 
    id.
     at 5755
    ¶ 350; and “‘add-on’ applications, content, and services that
    are generally information services,” 
    id.
     at 5750 ¶ 341, such as
    email and cloud-based storage programs, 
    id.
     at 5773 ¶ 376. It
    found that from the consumer’s perspective, “broadband
    Internet access service is today sufficiently independent of
    these information services that it is a separate offering.” 
    Id.
     at
    5757–58 ¶ 356.
    In support of its conclusion, the Commission pointed to
    record evidence demonstrating that consumers use broadband
    principally to access third-party content, not email and other
    add-on applications. “As more American households have
    gained access to broadband Internet access service,” the
    Commission explained, “the market for Internet-based
    services provided by parties other than broadband Internet
    access providers has flourished.” 
    Id.
     at 5753 ¶ 347. Indeed,
    from 2003 to 2015, the number of websites increased from
    “approximately 36 million” to “an estimated 900 million.” 
    Id.
    By one estimate, two edge providers, Netflix and YouTube,
    “account for 50 percent of peak Internet download traffic in
    North America.” 
    Id.
     at 5754 ¶ 349.
    That consumers focus on transmission to the exclusion of
    add-on applications is hardly controversial. Even the most
    limited examination of contemporary broadband usage reveals
    that consumers rely on the service primarily to access third-
    party content. The “typical consumer” purchases broadband
    to use “third-party apps such as Facebook, Netflix, YouTube,
    Twitter, or MLB.tv, or . . . to access any of thousands of
    websites.”       Computer & Communications Industry
    Association Amicus Br. 7. As one amicus succinctly
    explains, consumers today “pay telecommunications
    providers for access to the Internet, and access is exactly what
    26
    they get. For content, they turn to [the] creative efforts . . . of
    others.” Automattic Amicus Br. 1.
    Indeed, given the tremendous impact third-party internet
    content has had on our society, it would be hard to deny its
    dominance in the broadband experience. Over the past two
    decades, this content has transformed nearly every aspect of
    our lives, from profound actions like choosing a leader,
    building a career, and falling in love to more quotidian ones
    like hailing a cab and watching a movie. The same assuredly
    cannot be said for broadband providers’ own add-on
    applications.
    The Commission found, moreover, that broadband
    consumers not only focus on the offering of transmission but
    often avoid using the broadband providers’ add-on services
    altogether, choosing instead “to use their high-speed Internet
    connections to take advantage of competing services offered
    by third parties.” 2015 Open Internet Order, 30 FCC Rcd. at
    5753 ¶ 347. For instance, two third-party email services,
    Gmail and Yahoo! Mail, were “among the ten Internet sites
    most frequently visited during the week of January 17, 2015,
    with approximately 400 million and 350 million visits
    respectively.” 
    Id.
     at 5753 ¶ 348. Some “even advise
    consumers specifically not to use a broadband provider-based
    email address[] because a consumer cannot take that email
    address with them if he or she switches providers.” 
    Id.
    Amici Members of Congress in Support of Respondents
    provide many more examples of third-party content that
    consumers use in lieu of broadband provider content,
    examples that will be abundantly familiar to most internet
    users. “[M]any consumers,” they note, “have spurned the
    applications . . . offered by their broadband Internet access
    service provider, in favor of services and applications offered
    27
    by third parties, such as . . . news and related content on
    nytimes.com or washingtonpost.com or Google News; home
    pages on Microsoft’s MSN or Yahoo!’s ‘my.yahoo’; video
    content on Netflix or YouTube or Hulu; streaming music on
    Spotify or Pandora or Apple Music; and on-line shopping on
    Amazon.com or Target.com, as well as many others in each
    category.” Members of Congress for Resp’ts Amicus Br. 22.
    In support of its second conclusion—that from the user’s
    point of view, the standalone offering of broadband service
    provides telecommunications—the Commission explained
    that “[u]sers rely on broadband Internet access service to
    transmit ‘information of the user’s choosing,’ ‘between or
    among points specified by the user,’” without changing the
    form or content of that information. 2015 Open Internet
    Order, 30 FCC Rcd. at 5761 ¶ 361 (quoting 
    47 U.S.C. § 153
    (50)); see also 
    id.
     at 5762–63 ¶ 362. The Commission
    grounded that determination in record evidence that
    “broadband Internet access service is marketed today
    primarily as a conduit for the transmission of data across the
    Internet.” 
    Id.
     at 5757 ¶ 354. Specifically, broadband
    providers focus their advertising on the speed of transmission.
    For example, the Commission quoted a Comcast ad offering
    “the consistently fast speeds you need, even during peak
    hours”; an RCN ad promising the ability “to upload and
    download in a flash”; and a Verizon ad claiming that
    “[w]hatever your life demands, there’s a Verizon FiOS plan
    with the perfect upload/download speed for you.” 
    Id.
     at 5755
    ¶ 351 (alteration in original) (internal quotation marks
    omitted). The Commission further observed that “fixed
    broadband providers use transmission speeds to classify tiers
    of service offerings and to distinguish their offerings from
    those of competitors.” 
    Id.
    28
    Those advertisements, moreover, “link higher
    transmission speeds and service reliability with enhanced
    access to the Internet at large—to any ‘points’ a user may
    wish to reach.” 
    Id.
     at 5756 ¶ 352. For example, RCN brags
    that its service is “ideal for watching Netflix,” and Verizon
    touts its service as “work[ing] well for uploading and sharing
    videos on YouTube.” 
    Id.
     Based on the providers’ emphasis
    on how useful their services are for accessing third-party
    content, the Commission found that end users view broadband
    service as a mechanism to transmit data of their own choosing
    to their desired destination—i.e., as a telecommunications
    service.
    In concluding that broadband qualifies as a
    telecommunications service, the Commission explained that
    although broadband often relies on certain information
    services to transmit content to end users, these services “do
    not turn broadband Internet access service into a functionally
    integrated information service” because “they fall within the
    telecommunications system management exception.” 
    Id.
     at
    5765 ¶ 365. The Commission focused on two such services.
    The first, DNS, routes end users who input the name of a
    website to its numerical IP address, allowing users to reach
    the website without having to remember its multidigit
    address. 
    Id.
     at 5766 ¶ 366. The second, caching, refers to the
    process of storing copies of web content at network locations
    closer to users so that they can access it more quickly. 
    Id.
     at
    5770 ¶ 372. The Commission found that DNS and caching fit
    within the statute’s telecommunications management
    exception because both services are “simply used to facilitate
    the transmission of information so that users can access other
    services.” 
    Id.
    Petitioners assert numerous challenges to the
    Commission’s decision to reclassify broadband. Finding that
    29
    none has merit, we uphold the classification. Significantly,
    although our colleague believes that the Commission acted
    arbitrarily and capriciously when it reclassified broadband, he
    agrees that the Commission has statutory authority to classify
    broadband as a telecommunications service. Concurring &
    Dissenting Op. at 10.
    A.
    Before addressing petitioners’ substantive challenges to
    the Commission’s reclassification of broadband service, we
    must consider two procedural arguments, both offered by US
    Telecom.
    First, US Telecom asserts that the Commission violated
    section 553 of the Administrative Procedure Act, which
    requires that an NPRM “include . . . either the terms or
    substance of the proposed rule or a description of the subjects
    and issues involved.” 
    5 U.S.C. § 553
    (b)(3). According to US
    Telecom, the Commission violated this requirement because
    the NPRM proposed relying on section 706, not Title II; never
    explained that the Commission would justify reclassification
    based on consumer perception; and failed to signal that it
    would rely on the telecommunications management
    exception.
    Under the APA, an NPRM must “provide sufficient
    factual detail and rationale for the rule to permit interested
    parties to comment meaningfully.” Honeywell International,
    Inc. v. EPA, 
    372 F.3d 441
    , 445 (D.C. Cir. 2004) (internal
    quotation marks omitted). The final rule, however, “need not
    be the one proposed in the NPRM.” Agape Church, Inc. v.
    FCC, 
    738 F.3d 397
    , 411 (D.C. Cir. 2013). Instead, it “need
    only be a ‘logical outgrowth’ of its notice.”           Covad
    Communications Co. v. FCC, 
    450 F.3d 528
    , 548 (D.C. Cir.
    2006). An NPRM satisfies the logical outgrowth test if it
    30
    “expressly ask[s] for comments on a particular issue or
    otherwise ma[kes] clear that the agency [is] contemplating a
    particular change.” CSX Transportation, Inc. v. Surface
    Transportation Board, 
    584 F.3d 1076
    , 1081 (D.C. Cir. 2009).
    The Commission’s NPRM satisfied this standard.
    Although the NPRM did say that the Commission was
    considering relying on section 706, it also “expressly asked
    for comments” on whether the Commission should reclassify
    broadband: “[w]e seek comment on whether the Commission
    should rely on its authority under Title II of the
    Communications Act, including . . . whether we should revisit
    the Commission’s classification of broadband Internet access
    service as an information service . . . .” NPRM, 29 FCC Rcd.
    at 5612 ¶ 148 (footnote omitted).
    US Telecom’s second complaint—that the NPRM failed
    to provide a meaningful opportunity to comment on the
    Commission’s reliance on consumer perception—is equally
    without merit. In Brand X, the Supreme Court explained that
    classification under the Communications Act turns on “what
    the consumer perceives to be the . . . finished product.” 
    545 U.S. at 990
    . Given this, and given that the NPRM expressly
    stated that the Commission was considering reclassifying
    broadband as a telecommunications service, interested parties
    could “comment meaningfully” on the possibility that the
    Commission would follow Brand X and look to consumer
    perception.
    Brand X also provides the answer to US Telecom’s
    complaint about the telecommunications management
    exception. In Brand X, the Court made clear that to reclassify
    broadband as a telecommunications service, the Commission
    would need to conclude that the telecommunications
    component of broadband was “functionally separate” from the
    31
    information services component. 
    Id. at 991
    . Moreover, the
    dissent expressly noted that the Commission could reach this
    conclusion in part by determining that certain information
    services fit within the telecommunications management
    exception. “[The] exception,” the dissent explained, “would
    seem to apply to [DNS and caching]. DNS, in particular, is
    scarcely more than routing information . . . .” 
    Id.
     at 1012–13
    (Scalia, J., dissenting). As they could with consumer
    perception, therefore, interested parties could “comment
    meaningfully” on the Commission’s use of the
    telecommunications management exception.
    US Telecom next argues that the Commission violated
    the Regulatory Flexibility Act by failing to conduct an
    adequate Final Regulatory Flexibility Analysis regarding the
    effects of reclassification on small businesses. See 
    5 U.S.C. § 604
    (a). We lack jurisdiction to entertain this argument.
    Under the Communications Act, for a party to challenge an
    order based “on questions of fact or law upon which the
    Commission . . . has been afforded no opportunity to pass,” a
    party must “petition for reconsideration.” 
    47 U.S.C. § 405
    (a).
    Because the Commission included its Final Regulatory
    Flexibility Analysis in the Order, US Telecom had to file a
    petition for reconsideration if it wished to object to the
    analysis. US Telecom failed to do so.
    B.
    This brings us to petitioners’ substantive challenges to
    reclassification. Specifically, they argue that the Commission
    lacks statutory authority to reclassify broadband as a
    telecommunications service. They also argue that, even if it
    has such authority, the Commission failed to adequately
    explain why it reclassified broadband from an information
    service to a telecommunications service. Finally, they
    contend that the Commission had to determine that broadband
    32
    providers were common carriers under this court’s NARUC
    test in order to reclassify.
    1.
    In addressing petitioners’ first argument, we follow the
    Supreme Court’s decision in Brand X and apply Chevron’s
    two-step analysis. Brand X, 
    545 U.S. at 981
     (“[W]e apply the
    Chevron framework to the Commission’s interpretation of the
    Communications Act.”). At Chevron step one, we ask
    “whether Congress has directly spoken to the precise question
    at issue.” Chevron, 
    467 U.S. at 842
    . Where “the intent of
    Congress is clear, that is the end of the matter; for [we], as
    well as the agency, must give effect to the unambiguously
    expressed intent of Congress.” 
    Id.
     at 842–43. But if “the
    statute is silent or ambiguous with respect to the specific
    issue,” we proceed to Chevron step two, where “the question
    for the court is whether the agency’s answer is based on a
    permissible construction of the statute.” 
    Id. at 843
    .
    As part of its challenge to the Commission’s
    reclassification, US Telecom argues that broadband is
    unambiguously an information service, which would bar the
    Commission from classifying it as a telecommunications
    service. The Commission maintains, however, that Brand X
    established that the Communications Act is ambiguous with
    respect to the proper classification of broadband. As the
    Commission points out, the Court explained that whether a
    carrier provides a “telecommunications service” depends on
    whether it makes an “offering” of telecommunications.
    Brand X, 
    545 U.S. at 989
    ; see also 
    47 U.S.C. § 153
    (53) (“The
    term ‘telecommunications service’ means the offering of
    telecommunications for a fee directly to the public . . . .”
    (emphasis added)). The term “offering,” the Court held, is
    ambiguous. Brand X, 
    545 U.S. at 989
    .
    33
    Seeking to escape Brand X, US Telecom argues that the
    Court held only that the Commission could classify as a
    telecommunications service the “last mile” of transmission,
    which US Telecom defines as the span between the end user’s
    computer and the broadband provider’s computer. Here,
    however, the Commission classified “the entire broadband
    service from the end user all the way to edge providers” as a
    telecommunications service. US Telecom Pet’rs’ Br. 44.
    According to US Telecom, “[t]he ambiguity addressed in
    Brand X thus has no bearing here because the Order goes
    beyond the scope of whatever ambiguity [the statute]
    contains.”    
    Id.
     (second alteration in original) (internal
    quotation marks omitted).
    We have no need to resolve this dispute because, even if
    the Brand X decision was only about the last mile, the Court
    focused on the nature of the functions broadband providers
    offered to end users, not the length of the transmission
    pathway, in holding that the “offering” was ambiguous. As
    discussed earlier, the Commission adopted that approach in
    the Order in concluding that the term was ambiguous as to the
    classification question presented here: whether the “offering”
    of broadband internet access service can be considered a
    telecommunications service. In doing so, the Commission
    acted in accordance with the Court’s instruction in Brand X
    that the proper classification of broadband turns “on the
    factual particulars of how Internet technology works and how
    it is provided, questions Chevron leaves to the Commission to
    resolve in the first instance.” 
    545 U.S. at 991
    .
    US Telecom makes several arguments in support of its
    contrary position that broadband is unambiguously an
    information service. None persuades us. First, US Telecom
    contends that the statute’s text makes clear that broadband
    service “qualifies under each of the eight, independent parts
    34
    of the [information service] definition,” US Telecom Pet’rs’
    Br. 30—namely, that it “offer[s] . . . a capability for
    generating, acquiring, storing, transforming, processing,
    retrieving, utilizing, or making available information via
    telecommunications,” 
    47 U.S.C. § 153
    (24). Accordingly, US
    Telecom argues, broadband service “cannot fall within the
    mutually exclusive category of telecommunications service.”
    US Telecom Pet’rs’ Br. 30 (internal quotation marks and
    footnote omitted). But this argument ignores that under the
    statute’s definition of “information service,” such services are
    provided “via telecommunications.” 
    47 U.S.C. § 153
    (24).
    This, then, brings us back to the basic question: do broadband
    providers make a standalone offering of telecommunications?
    US Telecom’s argument fails to provide an unambiguous
    answer to that question.
    US Telecom next claims that 
    47 U.S.C. § 230
    , enacted as
    part of the Communications Decency Act of 1996, a portion
    of the Telecommunications Act, “confirms that Congress
    understood Internet access to be an information service.” US
    Telecom Pet’rs’ Br. 33. Section 230(b) states that “[i]t is the
    policy of the United States . . . to promote the continued
    development of the Internet and other interactive computer
    services and other interactive media.” 
    47 U.S.C. § 230
    (b)(1).
    In turn, section 230(f) defines an “interactive computer
    service” “[a]s used in this section” as “any information
    service, system, or access software provider that provides or
    enables computer access by multiple users to a computer
    server, including specifically a service or system that provides
    access to the Internet.” 
    Id.
     § 230(f)(2). According to US
    Telecom, this definition of “interactive computer service”
    makes clear that an information service “includes an Internet
    access service.” US Telecom Pet’rs’ Br. 33. As the
    Commission pointed out in the Order, however, it is “unlikely
    that Congress would attempt to settle the regulatory status of
    35
    broadband Internet access services in such an oblique and
    indirect manner, especially given the opportunity to do so
    when it adopted the Telecommunications Act of 1996.” 30
    FCC Rcd. at 5777 ¶ 386; see Whitman v. American Trucking
    Ass’ns, 
    531 U.S. 457
    , 468 (2001) (“Congress . . . does not
    alter the fundamental details of a regulatory scheme in vague
    terms or ancillary provisions—it does not, one might say, hide
    elephants in mouseholes.”).
    Finally, US Telecom argues that “[t]he statutory context
    and history confirm the plain meaning of the statutory text.”
    US Telecom Pet’rs’ Br. 33. According to US Telecom, while
    the Computer II regime was in effect, the Commission
    classified “gateway services allowing access to information
    stored by third parties” as enhanced services, and Congress
    incorporated that classification into the Communications Act
    when it enacted the Telecommunications Act’s
    information/telecommunications service dichotomy. 
    Id.
     at
    33–35. “Those ‘gateways,’” US Telecom insists, “involved
    the same ‘functions and services associated with Internet
    access.’” Id. at 34 (quoting In re Federal-State Joint Board on
    Universal Service, 13 FCC Rcd. 11,501 ¶ 75 (1998)). This
    argument suffers from a significant flaw: nothing in the
    Telecommunications Act suggests that Congress intended to
    freeze in place the Commission’s existing classifications of
    various services.       Indeed, such a reading of the
    Telecommunications Act would conflict with the Supreme
    Court’s holding in Brand X that classification of broadband
    “turns . . . on the factual particulars of how Internet
    technology works and how it is provided, questions Chevron
    leaves to the Commission to resolve in the first instance.”
    
    545 U.S. at 991
    .
    Amici Members of Congress in Support of Petitioners
    advance   an    additional   argument    that     post-
    36
    Telecommunications Act legislative history “demonstrates
    that Congress never delegated to the Commission” authority
    to regulate broadband service as a telecommunications
    service. Members of Congress for Pet’rs Amicus Br. 4. In
    support, they point out that Congress has repeatedly tried and
    failed to enact open internet legislation, confirming, in their
    view, that the Commission lacks authority to issue open
    internet rules. But as the Supreme Court has made clear,
    courts do not regard Congress’s “attention” to a matter
    subsequently resolved by an agency pursuant to statutory
    authority as “legislative history demonstrating a congressional
    construction of the meaning of the statute.” American
    Trucking Ass’ns v. Atchison, Topeka, & Santa Fe Railway
    Co., 
    387 U.S. 397
    , 416–17 (1967). Following this approach,
    we have rejected attempts to use legislative history to cabin an
    agency’s statutory authority in the manner amici propose. For
    example, in Advanced Micro Devices v. Civil Aeronautics
    Board, petitioners challenged the Civil Aeronautics Board’s
    rules adopting a more deferential approach to the regulation
    of international cargo rates. 
    742 F.2d 1520
    , 1527–28 (D.C.
    Cir. 1984). Petitioners asserted that the Board had no
    authority to promulgate the rules because “Congress
    deliberately eschewed the course now advanced by the
    [Board],” 
    id. at 1541
    , when it tried and failed to enact
    legislation that would have put “limits on the Board’s
    ratemaking functions regarding international cargo,” 
    id. at 1523
    . Rejecting petitioners’ argument, we explained that
    “Congress’s failure to enact legislation . . . d[oes] not
    preclude analogous rulemaking.”          
    Id.
     at 1542 (citing
    American Trucking Ass’ns, 
    387 U.S. at
    416–18). In that case,
    as here, the relevant question was whether the agency had
    statutory authority to promulgate its regulations, and, as we
    explained, “congressional inaction or congressional action
    short of the enactment of positive law . . . is often entitled to
    no weight” in answering that question. Id. at 1541. Amici
    37
    also argue that Congress’s grants to the Commission of
    “narrow authority over circumscribed aspects of the Internet”
    indicate that the Commission lacks “the authority it claims
    here.” Members of Congress for Pet’rs Amicus Br. 9. None
    of the statutes amici cite, however, have anything to do with
    the sort of common carrier regulations at issue here.
    Full Service Network also urges us to resolve this case at
    Chevron step one, though it takes the opposite position of US
    Telecom. According to Full Service Network, broadband is
    unambiguously a telecommunications service because it
    functions primarily as a transmission service. That argument
    clearly fails in light of Brand X, which held that classification
    of broadband as an information service was permissible.
    Brand X also requires that we reject intervenor
    TechFreedom’s argument that the reclassification issue is
    controlled by the Supreme Court’s decision in FDA v. Brown
    & Williamson Tobacco Corp., 
    529 U.S. 120
     (2000). In that
    case, the Court held that “Congress ha[d] clearly precluded
    the FDA from asserting jurisdiction to regulate tobacco
    products.” 
    Id. at 126
    . The Court emphasized that the FDA
    had disclaimed any authority to regulate tobacco products for
    more than eighty years and that Congress had repeatedly
    legislated against this background.           
    Id.
     at 143–59.
    Furthermore, the Court observed, if the FDA did have
    authority to regulate the tobacco industry, given its statutory
    obligations and its factual findings regarding the harmful
    effects of tobacco, the FDA would have had to ban tobacco
    products, a result clearly contrary to congressional intent. See
    
    id.
     at 135–43. If Congress sought to “delegate a decision of
    such economic and political significance” to the agency, the
    Court noted, it would have done so clearly. 
    Id. at 160
    .
    Relying on Brown & Williamson, TechFreedom urges us to
    38
    exercise “judicial skepticism of the [Commission’s] power
    grab.” TechFreedom Intervenor Br. 18.
    TechFreedom ignores Brand X. As explained above, the
    Supreme Court expressly recognized that Congress, by
    leaving a statutory ambiguity, had delegated to the
    Commission the power to regulate broadband service. By
    contrast, in Brown & Williamson the Court held that Congress
    had “precluded” the FDA from regulating cigarettes.
    This brings us, then, to petitioners’ and intervenors’
    Chevron step two challenges.
    First, US Telecom argues that the Commission’s
    classification is unreasonable because many broadband
    providers offer information services, such as email, alongside
    internet access.     According to US Telecom, because
    broadband providers still offer such services, consumers must
    perceive that those providers offer an information service.
    For its part, the Commission agreed that broadband providers
    offer email and other services, but simply concluded that
    “broadband Internet access service is today sufficiently
    independent of these information services that it is a separate
    offering.” 2015 Open Internet Order, 30 FCC Rcd. at 5758
    ¶ 356. US Telecom nowhere challenges that conclusion, and
    for good reason: the record contains extensive evidence that
    consumers perceive a standalone offering of transmission,
    separate from the offering of information services like email
    and cloud storage. See supra at 25–27.
    US Telecom next contends that the Commission’s
    reclassification of broadband was unreasonable because DNS
    and caching do not fall within the Communications Act’s
    telecommunications management exception. As noted above,
    that exception excludes from the definition of an information
    service “any [service] for the management, control, or
    39
    operation of a telecommunications system or the management
    of a telecommunications service.” 
    47 U.S.C. § 153
    (24). The
    Commission found that “[w]hen offered as part of a
    broadband Internet access service, caching [and] DNS [are]
    simply used to facilitate the transmission of information so
    that users can access other services.” 2015 Open Internet
    Order, 30 FCC Rcd. at 5770 ¶ 372. Challenging this
    interpretation, US Telecom argues that DNS and caching fall
    outside the exception because neither “manage[s] a
    telecommunications system or service,” US Telecom Pet’rs’
    Br. 39, but are instead examples of the “many core
    information-service functions associated with Internet
    access,” id. at 37. US Telecom claims that the Commission’s
    use of the telecommunications management exception was
    also unreasonable because the Commission “contends that the
    same functions—DNS and caching—are used for
    telecommunications management when offered as part of
    Internet access, but are an information service when third-
    party content providers similarly offer them.” Id. at 40. We
    are unpersuaded.
    First,     the   Commission      explained       that   the
    Communications Act’s telecommunications management
    exception encompasses those services that would have
    qualified as “adjunct-to-basic” under the Computer II regime.
    2015 Open Internet Order, 30 FCC Rcd. at 5766–67 ¶ 367
    (citing Non-Accounting Safeguards Order, 11 FCC Rcd. at
    21,958 ¶ 107). To qualify as an adjunct-to-basic service, a
    service had to be “‘basic in purpose and use’ in the sense that
    [it] facilitate[d] use of the network, and . . . [it] could ‘not
    alter the fundamental character of the [telecommunications
    service].’” Id. at 5767 ¶ 367 (last alteration in original)
    (quoting In re North American Telecommunications Ass’n,
    101 F.C.C. 2d 349, 359 ¶ 24, 360 ¶ 27 (1985)) (some internal
    quotation marks omitted). The Commission concluded that
    40
    DNS and caching satisfy this test because both services
    facilitate use of the network without altering the fundamental
    character of the telecommunications service. DNS does so by
    “allow[ing] more efficient use of the telecommunications
    network by facilitating accurate and efficient routing from the
    end user to the receiving party.” Id. at 5768 ¶ 368. Caching
    qualifies because it “enabl[es] the user to obtain more rapid
    retrieval of information through the network.” Id. at 5770
    ¶ 372 (internal quotation marks omitted). US Telecom does
    not challenge the applicability of the adjunct-to-basic
    standard, nor does it give us any reason to believe that the
    Commission’s application of that standard was unreasonable.
    See GTE Service Corp. v. FCC, 
    224 F.3d 768
    , 772 (D.C. Cir.
    2000) (“[W]e will defer to the [Commission’s] interpretation
    of [the Communications Act] if it is reasonable in light of the
    text, the structure, and the purpose of [the Communications
    Act].”).
    As to US Telecom’s second point, the Commission
    justified treating third-party DNS and caching services
    differently on the ground that when such services are
    “provided on a stand-alone basis by entities other than the
    provider of Internet access service[,] . . . there would be no
    telecommunications service to which [the services are]
    adjunct.” 2015 Open Internet Order, 30 FCC Rcd. at 5769
    ¶ 370 n.1046. Again, US Telecom has given us no basis for
    questioning the reasonableness of this conclusion. Once a
    carrier uses a service that would ordinarily be an information
    service—such as DNS or caching—to manage a
    telecommunications service, that service no longer qualifies
    as an information service under the Communications Act.
    The same service, though, when unconnected to a
    telecommunications service, remains an information service.
    41
    Intervenor TechFreedom makes one additional Chevron
    step two argument. It contends that this case resembles
    Utility Air Regulatory Group v. EPA, in which the Supreme
    Court reviewed EPA regulations applying certain statutory
    programs governing air pollution to greenhouse gases. 
    134 S. Ct. 2427
    , 2437 (2014). EPA had “tailored” the programs to
    greenhouse gases by using different numerical thresholds for
    triggering application of the programs than those listed in the
    statute because using “the statutory thresholds would [have]
    radically expand[ed] those programs.” 
    Id.
     at 2437–38.
    Rejecting this approach, the Supreme Court held that because
    the statute’s numerical thresholds were “unambiguous,” EPA
    had no “authority to ‘tailor’ [them] to accommodate its
    greenhouse-gas-inclusive interpretation of the permitting
    triggers.” 
    Id. at 2446
    . “[T]he need to rewrite clear provisions
    of the statute,” the Court declared, “should have alerted EPA
    that it had taken a wrong interpretive turn.” 
    Id.
     According to
    TechFreedom, the Commission’s need to extensively forbear
    from Title II similarly reveals the “incoherence” of its
    decision. TechFreedom Intervenor Br. 21.
    This case is nothing like Utility Air. Far from rewriting
    clear statutory language, the Commission followed an express
    statutory mandate requiring it to “forbear from applying any
    regulation or any provision” of the Communications Act if
    certain criteria are met. 
    47 U.S.C. § 160
    (a). Nothing in the
    Clean Air Act gave EPA any comparable authority.
    Accordingly, the Commission’s extensive forbearance does
    not suggest that the Order is unreasonable.
    2.
    We next consider US Telecom’s argument that the
    Commission failed to adequately explain why, having long
    classified broadband as an information service, it chose to
    reclassify it as a telecommunications service. Under the
    42
    APA, we must “determine whether the Commission’s actions
    were ‘arbitrary, capricious, an abuse of discretion, or
    otherwise not in accordance with law.’” Verizon, 740 F.3d at
    635 (quoting 
    5 U.S.C. § 706
    (2)(A)). As noted at the outset of
    our opinion, “[o]ur role in this regard is a limited one, and we
    will not substitute our judgment for that of the agency.”
    EarthLink, Inc. v. FCC, 
    462 F.3d 1
    , 9 (D.C. Cir. 2006).
    Provided that the Commission has “articulate[d] . . . a
    ‘rational connection between the facts found and the choice
    made,’” we will uphold its decision. Verizon, 740 F.3d at
    643–44 (alteration in original) (quoting State Farm, 
    463 U.S. at 52
    ) (some internal quotation marks omitted); see also
    FERC v. Electric Power Supply Ass’n, 
    136 S. Ct. 760
    , 784
    (2016) (“Our important but limited role is to ensure that [the
    agency] engaged in reasoned decisionmaking—that it
    weighed competing views, selected [an approach] with
    adequate support in the record, and intelligibly explained the
    reasons for making that choice.”).
    As relevant here, “[t]he APA’s requirement of reasoned
    decision-making ordinarily demands that an agency
    acknowledge and explain the reasons for a changed
    interpretation.” Verizon, 740 F.3d at 636. “An agency may
    not, for example, depart from a prior policy sub silentio or
    simply disregard rules that are still on the books.” FCC v.
    Fox Television Stations, Inc., 
    556 U.S. 502
    , 515 (2009). That
    said, although the agency “must show that there are good
    reasons for the new policy[,] . . . it need not demonstrate to a
    court’s satisfaction that the reasons for the new policy are
    better than the reasons for the old one.” 
    Id.
    US Telecom contends that the Commission lacked good
    reasons for reclassifying broadband because “as Verizon made
    clear, and as the [Commission] originally recognized, it could
    have adopted appropriate Open Internet rules based upon
    43
    § 706 without reclassifying broadband.” US Telecom Pet’rs’
    Br. 54 (internal citations omitted). But the Commission did
    not believe it could do so. Specifically, the Commission
    found it necessary to establish three bright-line rules, the anti-
    blocking, anti-throttling, and anti-paid-prioritization rules,
    2015 Open Internet Order, 30 FCC Rcd. at 5607 ¶ 14, all of
    which impose per se common carrier obligations by requiring
    broadband providers to offer indiscriminate service to edge
    providers, see Verizon, 740 F.3d at 651–52. “[I]n light of
    Verizon,” the Commission explained, “absent a classification
    of broadband providers as providing a ‘telecommunications
    service,’ the Commission could only rely on section 706 to
    put in place open Internet protections that steered clear of
    regulating broadband providers as common carriers per se.”
    2015 Open Internet Order, 30 FCC Rcd. at 5614 ¶ 42. This,
    in our view, represents a perfectly “good reason” for the
    Commission’s change in position.
    Raising an additional argument, US Telecom asserts that
    reclassification “will undermine” investment in broadband.
    US Telecom Pet’rs’ Br. 54. The partial dissent agrees,
    pointing specifically to 
    47 U.S.C. § 207
    , which subjects Title
    II common carriers to private complaints. Concurring &
    Dissenting Op. at 24. The Commission, however, reached a
    different conclusion with respect to reclassification’s impact
    on broadband investment. It found that “Internet traffic is
    expected to grow substantially in the coming years,” driving
    investment, 2015 Open Internet Order, 30 FCC Rcd. at 5792
    ¶ 412; that Title II regulation had not stifled investment when
    applied in other circumstances, 
    id.
     at 5793–94 ¶ 414; and that
    “major infrastructure providers have indicated that they will
    in fact continue to invest under the [Title II] framework,” 
    id.
    at 5795 ¶ 416. In any event, the Commission found that the
    virtuous cycle—spurred by the open internet rules—provides
    an ample counterweight, in that any harmful effects on
    44
    broadband investment “are far outweighed by positive effects
    on innovation and investment in other areas of the ecosystem
    that [its] core broadband polices will promote.” 
    Id.
     at 5791 ¶
    410. In reviewing these conclusions, we ask not whether they
    “are correct or are the ones that we would reach on our own,
    but only whether they are reasonable.” EarthLink, 
    462 F.3d at 12
     (internal quotation marks omitted). Moreover, “[a]n
    agency’s predictive judgments about areas that are within the
    agency’s field of discretion and expertise are entitled to
    particularly deferential review, as long as they are
    reasonable.” 
    Id.
     (internal quotation marks omitted). The
    Commission has satisfied this highly deferential standard. As
    to section 207, the Commission explained that “[a]lthough [it]
    appreciate[d] carriers’ concerns that [its] reclassification
    decision could create investment-chilling regulatory burdens
    and uncertainty, [it] believe[d] that any effects are likely to be
    short term and will dissipate over time as the marketplace
    internalizes [the] Title II approach.” 2015 Open Internet
    Order, 30 FCC Rcd. at 5791 ¶ 410. This too is precisely the
    kind of “predictive judgment[] . . . within the agency’s field of
    discretion and expertise” that we do not second guess.
    In a related argument, the partial dissent contends that the
    Commission lacked “good reasons” for reclassifying because
    its rules, particularly the General Conduct Rule, will decrease
    future investment in broadband by increasing regulatory
    uncertainty. Although US Telecom asserts in the introduction
    to its brief that the rules “will undermine future investment by
    large and small broadband providers,” US Telecom Pet’rs’ Br.
    4, it provides no further elaboration on this point and never
    challenges reclassification on the ground that the rules will
    harm broadband investment. As we have said before, “[i]t is
    not enough merely to mention a possible argument in the most
    skeletal way, leaving the court to do counsel’s work.” New
    York Rehabilitation Care Management, LLC v. NLRB, 506
    
    45 F.3d 1070
    , 1076 (D.C. Cir. 2007) (internal quotation marks
    omitted).    Given that no party adequately raised this
    argument, we decline to consider it. See In re Cheney, 334
    F.3d at 1108 (Reviewing courts “sit to resolve only legal
    questions presented and argued by the parties.”).
    Finally, the partial dissent disagrees with our conclusion
    that the Commission had “good reasons” to reclassify
    because, according to the partial dissent, it failed to make “a
    finding of market power or at least a consideration of
    competitive conditions.” Concurring & Dissenting Op. at 10.
    But nothing in the statute requires the Commission to make
    such a finding. Under the Act, a service qualifies as a
    “telecommunications service” as long as it constitutes an
    “offering of telecommunications for a fee directly to the
    public.” 
    47 U.S.C. § 153
    (53). As explained above, supra at
    24, when interpreting this provision in Brand X, the Supreme
    Court held that classification of broadband turns on consumer
    perception, see 
    545 U.S. at 990
     (explaining that classification
    depends on what “the consumer perceives to be the integrated
    finished product”). Nothing in Brand X suggests that an
    examination of market power or competition in the market is
    a prerequisite to classifying broadband. True, as the partial
    dissent notes, the Supreme Court cited the Commission’s
    findings regarding the level of competition in the market for
    cable broadband as further support for the agency’s decision
    to classify cable broadband as an information service. See 
    id. at 1001
     (describing the Commission’s conclusion that market
    conditions supported taking a deregulatory approach to cable
    broadband service). But citing the Commission’s economic
    findings as additional support for its approach is a far cry
    from requiring the Commission to find market power. The
    partial dissent also cites several Commission decisions in
    support of the proposition that the Commission has “for
    nearly four decades made the presence or prospect of
    46
    competition the touchstone for refusal to apply Title II.”
    Concurring & Dissenting Op. at 12. All of those cases,
    however, predate the 1996 Telecommunications Act, which
    established the statutory test that Brand X considered and that
    we apply here.
    US Telecom raises a distinct arbitrary and capricious
    argument. It contends that the Commission needed to satisfy
    a heightened standard for justifying its reclassification. As
    US Telecom points out, the Supreme Court has held that “the
    APA requires an agency to provide more substantial
    justification when ‘its new policy rests upon factual findings
    that contradict those which underlay its prior policy; or when
    its prior policy has engendered serious reliance interests that
    must be taken into account.’” Perez v. Mortgage Bankers
    Ass’n, 
    135 S. Ct. 1199
    , 1209 (2015) (quoting Fox Television,
    
    556 U.S. at 515
    ). “[I]t is not that further justification is
    demanded by the mere fact of policy change[,] but that a
    reasoned explanation is needed for disregarding facts and
    circumstances that underlay or were engendered by the prior
    policy.” Fox Television, 
    556 U.S. at
    515–16. Put another
    way, “[i]t would be arbitrary and capricious to ignore such
    matters.” 
    Id. at 515
    .
    US Telecom believes that the Commission failed to
    satisfy the heightened standard because it departed from
    factual findings it made regarding consumer perception in its
    2002 Cable Broadband Order without pointing to any changes
    in how consumers actually view broadband. According to US
    Telecom, even in 2002, when the Commission classified
    broadband as an information service, consumers used
    broadband primarily as a means to access third-party content
    and broadband providers marketed their services based on
    speed. As we have explained, however, although in 2002 the
    Commission found that consumers perceived an integrated
    47
    offering of an information service, in the present order the
    Commission cited ample record evidence supporting its
    current view that consumers perceive a standalone offering of
    transmission. See supra at 25–27. It thus satisfied the APA’s
    requirement that an agency provide a “reasoned
    explanation . . . for disregarding facts and circumstances that
    underlay . . . the prior policy.” Fox Television, 
    556 U.S. at
    515–16. Nothing more is required.
    Presenting an argument quite similar to US Telecom’s,
    the partial dissent asserts that the Commission needed to do
    more than justify its current factual findings because, in this
    case,    “the      agency explicitly invoke[d]            changed
    circumstances” as a basis for reclassifying broadband.
    Concurring & Dissenting Op. at 10. At least when an agency
    relies on a change in circumstances, the partial dissent
    reasons, “Fox requires us to examine whether there is really
    anything new.” Id. at 4. But we need not decide whether
    there “is really anything new” because, as the partial dissent
    acknowledges, id., the Commission concluded that changed
    factual circumstances were not critical to its classification
    decision:       “[E]ven assuming, arguendo, that the facts
    regarding how [broadband service] is offered had not
    changed, in now applying the Act’s definitions to these facts,
    we find that the provision of [broadband service] is best
    understood as a telecommunications service, as discussed
    [herein] . . . and disavow our prior interpretations to the extent
    they held otherwise.” 2015 Open Internet Order, 30 FCC
    Rcd. at 5761 ¶ 360 n.993.
    US Telecom next argues that the Commission “could not
    rationally abandon its prior policy without account[ing] for
    reliance interests that its prior policy engendered.” US
    Telecom Pet’rs’ Br. 51 (alteration in original) (internal
    quotation marks omitted). The Commission, however, did not
    48
    fail to “account” for reliance interests. Fox Television, 
    556 U.S. at 515
    . Quite to the contrary, it expressly considered the
    claims of reliance and found that “the regulatory status of
    broadband Internet access service appears to have, at most, an
    indirect effect (along with many other factors) on
    investment.” 2015 Open Internet Order, 30 FCC Rcd. at 5760
    ¶ 360. The Commission explained that “the key drivers of
    investment are demand and competition,” not the form of
    regulation. 
    Id.
     at 5792 ¶ 412. Additionally, the Commission
    noted that its past regulatory treatment of broadband likely
    had a particularly small effect on investment because the
    regulatory status of broadband service was settled for only a
    short period of time. 
    Id.
     at 5760–61 ¶ 360. As the
    Commission pointed out, just five years after Brand X upheld
    the Commission’s classification of broadband as an
    information service, the Commission asked in a notice of
    inquiry whether it should reclassify broadband as a
    telecommunications service. 
    Id.
     at 5760 ¶ 360.
    The partial dissent finds the Commission’s explanation
    insufficient and concludes that it failed “to make a serious
    assessment of [broadband providers’] reliance.” Concurring
    & Dissenting Op. at 8. With regard to the Commission’s
    conclusion that the regulatory status of broadband had only an
    indirect effect on investment, the partial dissent believes that
    this explanation is an “irrelevance” because “[t]he proposition
    that ‘many other factors’ affect investment is a truism” and
    thus the explanation “tells us little about how much” the prior
    classification “accounts for the current robust broadband
    infrastructure.” Id. at 5. But the Commission did more than
    simply state that the regulatory classification of broadband
    was one of many relevant factors. It went on to explain why
    other factors, namely, increased demand for broadband and
    increased competition to provide it, were more significant
    drivers of broadband investment. 2015 Open Internet Order,
    49
    30 FCC Rcd. at 5760 ¶ 360 & n.986; id. at 5792 ¶ 412. We
    also disagree with the partial dissent’s assertion that the
    Commission “misread[] the history of the classification of
    broadband” when it found that the unsettled regulatory
    treatment of broadband likely diminished the extent of
    investors’ reliance on the prior classification. Concurring &
    Dissenting Op. at 7. As explained above, supra at 13–16, the
    Commission classified broadband for the first time in 1998,
    when it determined that the phone lines used in DSL service
    qualified as a telecommunications service. See Advanced
    Services Order, 13 FCC Rcd. at 24,014 ¶ 3, 24,029–30 ¶¶ 35–
    36. Then, in 2002 the Commission classified cable broadband
    service as an information service, see Cable Broadband Order,
    17 FCC Rcd. at 4823 ¶¶ 39–40, a classification that was
    challenged and not definitively settled until 2005 when the
    Supreme Court decided Brand X. Only five years later, the
    Commission sought public comment on whether it should
    reverse     course     and    classify    broadband     as    a
    telecommunications service. See In re Framework for
    Broadband Internet Service, 25 FCC Rcd. at 7867 ¶ 2. Given
    this shifting regulatory treatment, it was not unreasonable for
    the Commission to conclude that broadband’s particular
    classification was less important to investors than increased
    demand. Contrary to our colleague, “[w]e see no reason to
    second guess these factual determinations, since the court
    properly defers to policy determinations invoking the
    [agency’s] expertise in evaluating complex market
    conditions.” Gas Transmission Northwest Corp. v. FERC,
    
    504 F.3d 1318
    , 1322 (D.C. Cir. 2007) (internal quotation
    marks and alteration omitted).
    3.
    Finally, we consider US Telecom’s argument that the
    Commission could not reclassify broadband without first
    determining that broadband providers were common carriers
    50
    under this court’s NARUC test. See National Ass’n of
    Regulatory Utility Commissioners v. FCC, 
    533 F.2d 601
    (D.C. Cir. 1976); National Ass’n of Regulatory Utility
    Commissioners v. FCC, 
    525 F.2d 630
     (D.C. Cir. 1976).
    Under that test, “a carrier has to be regulated as a common
    carrier if it will make capacity available to the public
    indifferently or if the public interest requires common carrier
    operation.” Virgin Islands Telephone Corp. v. FCC, 
    198 F.3d 921
    , 924 (D.C. Cir. 1999) (internal quotation marks omitted).
    As the Commission points out, however, this argument
    ignores that the Communications Act “provides that ‘[a]
    telecommunications carrier shall be treated as a common
    carrier . . . to the extent that it is engaged in providing
    telecommunications services,’” Resp’ts’ Br. 79 (alteration and
    omission in original) (quoting 
    47 U.S.C. § 153
    (51)), and that
    “[t]he Act thus authorizes—indeed, requires—broadband
    providers to be treated as common carriers once they are
    found to offer telecommunications service,” 
    id.
                The
    Communications Act in turn defines a telecommunications
    service as “the offering of telecommunications for a fee
    directly to the public,” 
    47 U.S.C. § 153
    (53), and the
    Commission found that broadband providers satisfy this
    statutory test:       “[h]aving affirmatively determined that
    broadband          Internet    access       service   involves
    ‘telecommunications,’ we also find . . . that broadband
    Internet access service providers offer broadband Internet
    access service ‘directly to the public.’” 2015 Open Internet
    Order, 30 FCC Rcd. at 5763 ¶ 363. Other than challenging
    the Commission’s interpretation of the term “offering”—an
    argument which we have already rejected, see supra section
    II.B.1—US Telecom never questions the Commission’s
    application of the statute’s test for common carriage.
    Moreover, US Telecom cites no case, nor are we aware of
    one, holding that when the Commission invokes the statutory
    test for common carriage, it must also apply the NARUC test.
    51
    III.
    Having thus rejected petitioners’ arguments against
    reclassification, we turn to US Telecom’s challenges to the
    Commission’s regulation of interconnection arrangements—
    arrangements that broadband providers make with other
    networks to exchange traffic in order to ensure that their end
    users can access edge provider content anywhere on the
    internet. Broadband providers have such arrangements with
    backbone networks, as well as with certain edge providers,
    such as Netflix, that connect directly to broadband provider
    networks. In the Order, the Commission found that regulation
    of interconnection arrangements was necessary to ensure
    broadband providers do not “use terms of interconnection to
    disadvantage edge providers” or “prevent[] consumers from
    reaching the services and applications of their choosing.”
    2015 Open Internet Order, 30 FCC Rcd. at 5694 ¶ 205.
    Several commenters, the Commission pointed out, had
    emphasized “the potential for anticompetitive behavior on the
    part of broadband Internet access service providers that serve
    as gatekeepers to the edge providers . . . seeking to deliver
    Internet traffic to the broadband providers’ end users.” Id. at
    5691 ¶ 200.
    As authority for regulating interconnection arrangements,
    the Commission relied on Title II. “Broadband Internet
    access service,” it explained, “involves the exchange of traffic
    between a . . . broadband provider and connecting networks,”
    since “[t]he representation to retail customers that they will be
    able to reach ‘all or substantially all Internet endpoints’
    necessarily includes the promise to make the interconnection
    arrangements necessary to allow that access.” Id. at 5693–94
    ¶ 204. Because the “same data is flowing between the end
    user and edge consumer,” the end user necessarily
    experiences any discriminatory treatment of the edge
    provider, the Commission reasoned, making interconnection
    52
    “simply derivative of” the service offered to end users. Id. at
    5748–49 ¶ 339.
    As a result, the Commission concluded that it could
    regulate interconnection arrangements under Title II as a
    component of broadband service. Id. at 5686 ¶ 195. It
    refrained, however, from applying the General Conduct Rule
    or any of the bright-line rules to interconnection arrangements
    because, given that it “lack[ed] [a] background in practices
    addressing Internet traffic exchange,” it would be “premature
    to adopt prescriptive rules to address any problems that have
    arisen or may arise.” Id. at 5692–93 ¶ 202. Rather, it
    explained that interconnection disputes would be evaluated on
    a case-by-case basis under sections 201, 202, and 208 of the
    Communications Act. See id. at 5686–87 ¶ 195. US Telecom
    presents two challenges to the Commission’s decision to
    regulate interconnection arrangements under Title II, one
    procedural and one substantive. We reject both.
    Echoing its arguments with respect to reclassification, US
    Telecom first claims that the NPRM provided inadequate
    notice that the Commission would regulate interconnection
    arrangements under Title II. As we noted above, an NPRM
    satisfies APA notice obligations when it “expressly ask[s] for
    comments on a particular issue or otherwise ma[kes] clear
    that the agency [is] contemplating a particular change.” CSX
    Transportation, Inc., 584 F.3d at 1081. The NPRM did just
    that. It expressly asked whether the Commission should
    apply its new rules—rules which it had signaled might depend
    upon Title II reclassification, NPRM, 29 FCC Rcd. at 5612
    ¶ 148—to interconnection arrangements.           The NPRM
    explained that the 2010 Open Internet Order had applied only
    “to a broadband provider’s use of its own network . . . but
    [had] not appl[ied] . . . to the exchange of traffic between
    networks.” NPRM, 29 FCC Rcd. at 5582 ¶ 59. Although the
    53
    Commission “tentatively conclude[d] that [it] should maintain
    this approach, . . . [the NPRM sought] comment on whether
    [the Commission] should change [its] conclusion.” Id.
    US Telecom insists that the NPRM was nonetheless
    inadequate because it nowhere suggested that the Commission
    might justify regulating interconnection arrangements under
    Title II on the basis that they are a component of the offering
    of telecommunications to end users. Under the APA, an
    NPRM provides adequate notice as long as it reveals the
    “substance of the proposed rule or a description of the
    subjects and issues involved.” 
    5 U.S.C. § 553
    (b)(3). An
    NPRM does so if it “provide[s] sufficient factual detail and
    rationale for the rule to permit interested parties to comment
    meaningfully.” Honeywell International, Inc., 
    372 F.3d at 445
     (internal quotation marks omitted). Again, the NPRM
    did just that. It asked whether the Commission should expand
    its reach beyond “a broadband provider’s use of its own
    network” in order to “ensure that a broadband provider would
    not be able to evade our open Internet rules by engaging in
    traffic exchange practices.” NPRM, 29 FCC Rcd. at 5582
    ¶ 59. By focusing on the threat that broadband providers
    might block edge provider access to end users at an earlier
    point in the transmission pathway, the NPRM allowed
    interested parties to comment meaningfully on the possibility
    that the Commission would consider interconnection
    arrangements to be part of the offering of telecommunications
    to end users. Indeed, interested parties interpreted the NPRM
    as presenting just that possibility. To take one example,
    COMPTEL explained in its comments that “as feared by the
    Commission in its [NPRM], a [broadband] provider can
    simply evade the Commission’s 2010 rules by moving its
    demand for an access fee upstream to the entry point to the
    [broadband provider’s network].” Letter from Markham C.
    Erickson, Counsel to COMPTEL, to Marlene H. Dortch,
    54
    FCC, GN Dkt. Nos. 14-28 & 10-127, at 10 (Feb. 19, 2015).
    Because “[t]he interconnection point is simply a literal
    extension of the [broadband provider’s network],”
    COMPTEL explained, “applying the same open Internet rules
    to the point of interconnection is a logical extension of the
    2010 Open Internet Order and clearly in line with the
    Commission’s . . . proposal [in the NPRM].” 
    Id.
    US Telecom next argues that our decision in Verizon
    prevents the Commission from regulating interconnection
    arrangements under Title II without first classifying the
    arrangements as an offering of telecommunications to edge
    providers and backbone networks. As US Telecom points
    out, Verizon recognized that broadband, and thus
    interconnection arrangements, provides a service not only to
    end users but also to edge providers and backbone networks,
    namely, the ability to reach the broadband provider’s users.
    Verizon, 740 F.3d at 653. According to US Telecom, Verizon
    therefore requires the Commission to classify this service to
    edge     providers    and    backbone     networks    as    a
    telecommunications       service   before     it    regulates
    interconnection arrangements under Title II.
    US Telecom misreads Verizon. Although Verizon does
    recognize that broadband providers’ delivery of broadband to
    end users also provides a service to edge providers, id., it does
    not hold that the Commission must classify broadband as a
    telecommunications service in both directions before it can
    regulate the interconnection arrangements under Title II. The
    problem in Verizon was not that the Commission had
    misclassified the service between carriers and edge providers
    but that the Commission had failed to classify broadband
    service as a Title II service at all. The Commission overcame
    this problem in the Order by reclassifying broadband
    55
    service—and the interconnection arrangements necessary to
    provide it—as a telecommunications service.
    IV.
    We now turn to the Commission’s treatment of mobile
    broadband service, i.e., high-speed internet access for mobile
    devices such as smartphones and tablets. As explained above,
    the Commission permissibly found that mobile broadband—
    like all broadband—is a telecommunications service subject
    to common carrier regulation under Title II of the
    Communications Act. We address here a second set of
    provisions that pertain to the treatment of mobile broadband
    as common carriage.
    Those provisions, found in Title III of the
    Communications Act, segregate “mobile services” into two,
    mutually exclusive categories: “commercial mobile services”
    and “private mobile services.” 
    47 U.S.C. § 332
    (c). Providers
    of commercial mobile services—mobile services that are,
    among other things, available “to the public” or “a substantial
    portion of the public”—are subject to common carrier
    regulation. 
    Id.
     § 332(c)(1), (d)(1). Providers of private
    mobile services, by contrast, “shall not . . . be treated as []
    common carrier[s].” Id. § 332(c)(2).
    In 2007, the Commission initially classified mobile
    broadband as a private mobile service. At the time, the
    Commission considered mobile broadband a “nascent”
    service. 2007 Wireless Order, 22 FCC Rcd. at 5922 ¶ 59. In
    the 2015 Order we now review, the Commission found that,
    “[i]n sharp contrast to 2007,” the “mobile broadband
    marketplace has evolved such that hundreds of millions of
    consumers now use mobile broadband to access the Internet.”
    2015 Open Internet Order, 30 FCC Rcd. at 5785 ¶ 398. The
    Commission thus concluded that “today’s mobile broadband
    56
    Internet access service, with hundreds of millions of
    subscribers,” is not a “private” mobile service “that offer[s]
    users access to a discrete and limited set of endpoints.” Id. at
    5788–89 ¶ 404.       Rather, “[g]iven the universal access
    provided today and in the foreseeable future by and to mobile
    broadband and its present and anticipated future penetration
    rates in the United States,” the Commission decided to
    “classify[] mobile broadband Internet access as a commercial
    mobile service” subject to common carrier regulation. Id. at
    5786 ¶ 399; see generally id. at 5778–88 ¶¶ 388–403.
    Petitioners CTIA and AT&T (“mobile petitioners”)
    challenge the Order’s reclassification of mobile broadband as
    a commercial mobile service.          In their view, mobile
    broadband is, and must be treated as, a private mobile service,
    and therefore cannot be subject to common carrier regulation.
    We reject mobile petitioners’ arguments and find that the
    Commission’s reclassification of mobile broadband as a
    commercial mobile service is reasonable and supported by the
    record.
    A.
    In assessing whether the Commission permissibly
    reclassified mobile broadband as a commercial rather than a
    private mobile service, we begin with an overview of the
    governing statutory and regulatory framework and of the
    Commission’s application of that framework to mobile
    broadband. The statute defines “commercial mobile service”
    as “any mobile service . . . that is provided for profit and
    makes interconnected service available (A) to the public or
    (B) to such classes of eligible users as to be effectively
    available to a substantial portion of the public, as specified by
    regulation by the Commission.” 
    47 U.S.C. § 332
    (d)(1). The
    statute then defines “private mobile service” strictly in the
    negative, i.e., as “any mobile service . . . that is not a
    57
    commercial mobile service or the functional equivalent of a
    commercial mobile service, as specified by regulation by the
    Commission.” 
    Id.
     § 332(d)(3).
    Because private mobile service is a residual category
    defined in relation to commercial mobile service, the
    definition of commercial mobile service is the operative one
    for our purposes. There is no dispute that mobile broadband
    meets three of the four parts of the statutory definition of
    commercial mobile service. Mobile broadband is a “mobile
    service”; it “is provided for profit”; and it is available “to the
    public” or “a substantial portion of the public.”               Id.
    § 332(d)(1). In those respects, mobile broadband bears the
    hallmarks of a commercial—and hence not a private—mobile
    service. The sole remaining question is whether mobile
    broadband also “makes interconnected service available.” Id.
    The statute defines “interconnected service” as “service
    that is interconnected with the public switched network (as
    such terms are defined by regulation by the Commission).”
    Id. § 332(d)(2). Until the Order, the Commission in turn
    defined the “public switched network” as a set of telephone
    (cellular and landline) networks, with users’ ten-digit
    telephone numbers making up the interconnected endpoints of
    the network. Specifically, “public switched network” meant
    “[a]ny common carrier switched network . . . that use[s] the
    North American Numbering Plan in connection with the
    provision of switched services.” 
    47 C.F.R. § 20.3
     (prior
    version effective through June 11, 2015). The “North
    American Numbering Plan” (NANP) is the ten-digit
    telephone numbering plan used in the United States. See In re
    Implementation       of    Sections 3(n) & 332 of the
    Communications Act (“1994 Order”), 9 FCC Rcd. 1411, 1437
    ¶ 60 n.116 (1994).
    58
    In 1994, when the Commission initially established that
    definition of “public switched network,” cellular telephone
    (i.e., mobile voice) service was the major mobile service;
    mobile broadband did not yet exist. Noting that the “purpose
    of the public switched network is to allow the public to send
    or receive messages to or from anywhere in the nation,” the
    Commission observed that the NANP fulfilled that purpose by
    providing users with “ubiquitous access” to all other users.
    
    Id.
     at 1436–37 ¶¶ 59–60; see 2015 Open Internet Order, 30
    FCC Rcd. at 5779 ¶ 391. Because mobile voice users could
    interconnect with the public switched network as then defined
    (the network of ten-digit telephone numbers), mobile voice
    was classified as a “commercial”—as opposed to “private”—
    “mobile service.” 1994 Order, 9 FCC Rcd. at 1454–55 ¶ 102.
    It therefore was subject to common carrier treatment.
    In 2007, the Commission first classified the then-
    emerging platform of mobile broadband. The Commission
    determined that mobile broadband users could not
    interconnect with the public switched network—defined at the
    time as the telephone network—because mobile broadband
    uses IP addresses, not telephone numbers. See 2015 Open
    Internet Order, 30 FCC Rcd. at 5784 ¶ 397; 2007 Wireless
    Order, 22 FCC Rcd. at 5917–18 ¶ 45. Mobile broadband thus
    was not considered an “interconnected service” (or, therefore,
    a commercial mobile service), i.e., a “service that is
    interconnected with the public switched network” as that term
    was then “defined by . . . the Commission.” 
    47 U.S.C. § 332
    (d)(2). Presumably in light of mobile broadband’s
    “nascent” status at the time, 2007 Wireless Order, 22 FCC
    Rcd. at 5922 ¶ 59, the Commission gave no evident
    consideration to expanding its definition of the “public
    switched network” so as to encompass IP addresses in
    addition to telephone numbers.
    59
    In the 2015 Order, the Commission determined that it
    should expand its definition of the public switched network in
    that fashion to “reflect[] the current network landscape.” 30
    FCC Rcd. at 5779 ¶ 391; see 
    id.
     at 5786 ¶ 399. The
    Commission took note of “evidence of the extensive changes
    that have occurred in the mobile marketplace.” 
    Id.
     at 5785–
    86 ¶ 398. For instance, as of the end of 2014, nearly three-
    quarters “of the entire U.S. age 13+ population was
    communicating with smart phones,” and “by 2019,”
    according to one forecast, “North America will have nearly
    90% of its installed base[] converted to smart devices and
    connections.” 
    Id.
     at 5785 ¶ 398. In addition, the Commission
    noted that the “hundreds of millions of consumers” who
    already “use[d] mobile broadband” as of 2015 could “send or
    receive communications to or from anywhere in the nation,
    whether connected with other mobile broadband subscribers,
    fixed broadband subscribers, or the hundreds of millions of
    websites available to them over the Internet.” 
    Id.
     Those
    significant    developments,      the    Commission     found,
    “demonstrate[] the ubiquity and wide scale use of mobile
    broadband Internet access service today.” 
    Id.
     at 5786 ¶ 398.
    The upshot is that, just as mobile voice (i.e., cellular
    telephone) service in 1994 provided “ubiquitous access” for
    members of the public to communicate with one another
    “from anywhere in the nation,” mobile broadband by 2015
    had come to provide the same sort of ubiquitous access. 
    Id.
     at
    5779–80 ¶ 391, 5785–86 ¶¶ 398–99. And the ubiquitous
    access characterizing both mobile voice and mobile
    broadband stands in marked contrast to “the private mobile
    service[s] of 1994, such as a private taxi dispatch service,
    services that offered users access to a discrete and limited set
    of endpoints.” 
    Id.
     at 5789 ¶ 404; see 1994 Order, 9 FCC Rcd.
    at 1414 ¶ 4. In recognition of the similarity of mobile
    broadband to mobile voice as a universal medium of
    60
    communication for the general public—and the dissimilarity
    of mobile broadband to closed private networks such as those
    used by taxi companies or local police and fire departments—
    the Commission in 2015 sought to reclassify “today’s broadly
    available mobile broadband” service as a commercial mobile
    service like mobile voice, rather than as a private mobile
    service like those employed by closed police or fire
    department networks. 2015 Open Internet Order, 30 FCC
    Rcd. at 5786 ¶ 399; see 1994 Order, 9 FCC Rcd. at 1414 ¶ 4.
    Aligning mobile broadband with mobile voice based on their
    affording similarly ubiquitous access, moreover, was in
    keeping with Congress’s objective in establishing a defined
    category of “commercial mobile services” subject to common
    carrier treatment: to “creat[e] regulatory symmetry among
    similar mobile services.” 1994 Order, 9 FCC Rcd. at 1413
    ¶ 2; see 2015 Open Internet Order, 30 FCC Rcd. at 5786
    ¶ 399; H.R. Rep. No. 103-111 at 259 (May 25, 1993) (noting
    that amendments to section 332 were intended to ensure “that
    services that provide equivalent mobile services are regulated
    in the same manner”).
    In the interest of achieving that regulatory symmetry and
    bringing mobile broadband into alignment with mobile voice
    as a commercial mobile service, the Commission updated its
    definition of the “public switched network” to include both
    users reachable by ten-digit phone numbers and users
    reachable by IP addresses. See 2015 Open Internet Order, 30
    FCC Rcd. at 5779 ¶ 391. The newly expanded definition of
    “public switched network” thus covers “the network that
    includes any common carrier switched network . . . that use[s]
    the North American Numbering Plan, or public IP addresses,
    in connection with the provision of switched services.” 
    Id.
    (emphasis added) (alteration in original); 
    47 C.F.R. § 20.3
    ;
    see Bell Atlantic Telephone Cos. v. FCC, 
    206 F.3d 1
    , 4 (D.C.
    Cir. 2000) (“[T]he internet is a ‘distributed packet-switched
    61
    network.’”). And because the public switched network now
    includes IP addresses, the Commission found that mobile
    broadband qualifies as an “interconnected service,” i.e.,
    “service that is interconnected with the public switched
    network” as redefined. 
    47 U.S.C. § 332
    (d)(2); see 2015 Open
    Internet Order, 30 FCC Rcd. at 5779–80 ¶ 391, 5786 ¶ 399.
    According to the Commission, then, mobile broadband
    meets all parts of the statutory definition of a “commercial
    mobile service” subject to common carrier regulation: it is a
    “mobile service . . . that is provided for profit and makes
    interconnected service available . . . to the public or . . . a
    substantial portion of the public.” 
    47 U.S.C. § 332
    (d)(1). We
    find the Commission’s reclassification of mobile broadband
    as a commercial mobile service under that definition to be
    reasonable and supported by record evidence demonstrating
    the “rapidly growing and virtually universal use of mobile
    broadband service” today. 2015 Open Internet Order, 30 FCC
    Rcd. at 5786 ¶ 399. In support of its reclassification decision,
    the Commission relied on, and recounted in detail, evidence
    of the explosive growth of mobile broadband service and its
    near universal use by the public. See 
    id.
     at 5635–38 ¶¶ 88–92,
    5779 ¶ 391, 5785–86 ¶¶ 398–99. In the face of that evidence,
    we see no basis for concluding that the Commission was
    required in 2015 to continue classifying mobile broadband as
    a “private” mobile service.
    B.
    Mobile petitioners offer two principal arguments in
    support of their position that mobile broadband nonetheless
    must be treated as a private mobile service rather than a
    commercial mobile service. First, they argue that “public
    switched network” is a term of art confined to the public
    switched telephone network. Second, they contend that, even
    if the Commission can expand the definition of public
    62
    switched network to encompass users with IP addresses in
    addition to users with telephone numbers, mobile broadband
    still fails to qualify as an “interconnected service.”
    We reject both arguments. In mobile petitioners’ view,
    mobile broadband (or any non-telephone mobile service)—no
    matter how universal, widespread, and essential a medium of
    communication for the public it may become—must always
    be considered a “private mobile service” and can never be
    considered a “commercial mobile service.” Nothing in the
    statute compels attributing to Congress such a wooden,
    counterintuitive understanding of those categories. Rather,
    Congress expressly delegated to the Commission the authority
    to define—and hence necessarily to update and revise—those
    categories’ key definitional components, “public switched
    network” and “interconnected service.” 
    47 U.S.C. § 332
    (d);
    see 2015 Open Internet Order, 30 FCC Rcd. at 5783–84
    ¶ 396.
    “In this sort of case, there is no need to rely on the
    presumptive delegation to agencies of authority to define
    ambiguous or imprecise terms we apply under the Chevron
    doctrine, for the delegation of interpretative authority is
    express.” Women Involved in Farm Economics v. U.S.
    Department of Agriculture, 
    876 F.2d 994
    , 1000–01 (D.C. Cir.
    1989) (citation omitted); see Rush University Medical Center
    v. Burwell, 
    763 F.3d 754
    , 760 (7th Cir. 2014); 2015 Open
    Internet Order, 30 FCC Rcd. at 5783 ¶ 396 & n.1145. We
    find the Commission’s exercise of that express definitional
    authority to be a reasoned and reasonable interpretation of the
    statute.       We therefore sustain the Commission’s
    reclassification of mobile broadband as a commercial mobile
    service against mobile petitioners’ challenges. In light of that
    disposition, we need not address the Commission’s alternative
    finding that mobile broadband, even if not a commercial
    63
    mobile service, is still subject to common carrier treatment as
    the “functional equivalent” of a commercial mobile service.
    See 
    47 U.S.C. § 332
    (d)(3); 2015 Open Internet Order, 30 FCC
    Rcd. at 5788–90 ¶¶ 404–08.
    1.
    We first consider mobile petitioners’ challenge to the
    Commission’s updated definition of “public switched
    network.” That term, as set out above, forms an integral
    component of the statutory definition of “commercial mobile
    service.”      Any such service must qualify as an
    “interconnected service,” defined in the statute as “service
    that is interconnected with the public switched network.” 
    47 U.S.C. § 332
    (d)(1)–(2). And Congress expressly gave the
    Commission the authority to define the public switched
    network, 
    id.
     § 332(d)(2), which the Commission exercised by
    revising its definition in the Order. As we have explained, the
    Commission, relying on the growing universality of mobile
    broadband as a medium of communication for the public,
    expanded the definition of the public switched network so that
    it now uses IP addresses in addition to telephone numbers in
    connection with the provision of switched services.
    Mobile petitioners argue that Congress intended “public
    switched network” to mean—forever—“public switched
    telephone network,” and that the Commission thus lacks
    authority to expand the definition of the network to include
    endpoints other than telephone numbers.              We are
    unpersuaded. Mobile petitioners’ interpretation necessarily
    contemplates adding a critical word (“telephone”) that
    Congress left out of the statute, an unpromising avenue for an
    argument about the meaning of the words Congress used.
    See, e.g., Adirondack Medical Center v. Sebelius, 
    740 F.3d 692
    , 699–700 (D.C. Cir. 2014); Public Citizen, Inc. v. Rubber
    Manufacturers Ass’n, 
    533 F.3d 810
    , 816 (D.C. Cir. 2008). If
    64
    Congress meant for the phrase “public switched network” to
    carry the more restrictive meaning attributed to it by mobile
    petitioners, Congress could (and presumably would) have
    used the more limited—and more precise—term “public
    switched telephone network.” Indeed, Congress used that
    precise formulation in another, later-enacted statute. See 
    18 U.S.C. § 1039
    (h)(4). Here, though, Congress elected to use
    the more general term “public switched network,” which by
    its plain language can reach beyond telephone networks
    alone. See 2015 Open Internet Order, 30 FCC Rcd. at 5783
    ¶ 396.
    Not only did Congress decline to invoke the term “public
    switched telephone network,” but it also gave the
    Commission express authority to define the broader term it
    used instead. See 
    47 U.S.C. § 332
    (d)(2). Mobile petitioners
    conceive of “public switched network” as a term of art
    referring only to a network using telephone numbers. But if
    that were so, it is far from clear why Congress would have
    invited the Commission to define the term, rather than simply
    setting out its ostensibly fixed meaning in the statute. We
    instead agree with the Commission that, in granting the
    Commission general definitional authority, Congress
    “expected the notion [of the public switched network] to
    evolve and therefore charged the Commission with the
    continuing obligation to define it.” 2015 Open Internet Order,
    30 FCC Rcd. at 5783 ¶ 396.
    It is of no moment that Congress, in another statute, used
    the term “public switched network” in a context indicating an
    intention to refer to the telephone network. See 
    47 U.S.C. § 1422
    (b)(1)(B)(ii) (referring to “the public Internet or the
    public switched network”). That statute, unlike section
    332(d)(2), contains no grant of authority to the Commission to
    define the term. And it was enacted during the time when the
    65
    Commission’s prior, longstanding regulatory definition of
    “public switched network” was in effect. Because the
    Commission at the time had defined the “public switched
    network” by reference to the telephone network, it is
    unsurprising that Congress would have assumed the term to
    have that meaning. But that assumption by no means
    indicates that Congress meant to divest the Commission of the
    definitional authority it had expressly granted the
    Commission in section 332(d)(2). We do not understand
    Congress’s express grant of definitional authority to have
    come burdened with an unstated intention to compel the
    Commission to forever retain a definition confined to one
    specific type of “public switched network,” i.e., the telephone
    network.
    We therefore reject mobile petitioners’ counter-textual
    argument that the statutory phrase “public switched network”
    must be understood as if Congress had used the phrase
    “public switched telephone network.” Instead, the more
    general phrase “public switched network,” by its terms,
    reaches any network that is both “public” and “switched.”
    Mobile petitioners do not dispute that a network using both IP
    addresses and telephone numbers is “public” and “switched.”
    As the Commission explained, its expansion of the network to
    include the use of IP addresses involves a “switched” network
    in that it “reflects the emergence and growth of packet
    switched Internet Protocol-based networks,” and it also
    involves a “public” network in that “today’s broadband
    Internet access networks use their own unique addressing
    identifier, IP addresses, to give users a universally recognized
    format for sending and receiving messages across the country
    and worldwide.” 2015 Open Internet Order, 30 FCC Rcd. at
    5779–80 ¶ 391 (emphasis added). The Commission thus
    permissibly considered a network using telephone numbers
    and IP addresses to be a “public switched network.”
    66
    2.
    Mobile petitioners next challenge the Commission’s
    understanding of “interconnected service.” That term, too, is
    an integral part of the definition of commercial mobile
    service.    A commercial mobile service must “make[]
    interconnected service available . . . to the public or to . . . a
    substantial portion of the public.” 
    47 U.S.C. § 332
    (d)(1).
    And “interconnected service” is “service that is
    interconnected with the public switched network.” 
    Id.
    § 332(d)(2). As with the phrase “public switched network,”
    Congress gave the Commission express authority to define the
    term “interconnected service.” Id.
    The Commission has defined “interconnected service” as
    a service “that gives subscribers the capability to
    communicate to or receive communication from all other
    users on the public switched network.” 
    47 C.F.R. § 20.3
    (prior version effective through June 11, 2015); see 2015
    Open Internet Order, 30 FCC Rcd. at 5779 ¶ 390. (We note
    that, in the 2015 Order, the Commission excised the word
    “all” from that definition. But as we explain below, the
    Commission considered that adjustment a purely conforming
    one with no substantive effect; we use the prior language to
    confirm that mobile broadband would qualify as
    interconnected service regardless of the Commission’s
    adjustment.)
    The question under the Commission’s definition of
    “interconnected service,” then, is whether mobile broadband
    “gives subscribers the capability to communicate to or receive
    communication from all other users on the public switched
    network” as redefined to encompass devices using both IP
    addresses and telephone numbers. 
    47 C.F.R. § 20.3
     (prior
    version effective through June 11, 2015). The Commission
    reasonably found that mobile broadband gives users that
    67
    “capability.” See 2015 Open Internet Order, 30 FCC Rcd. at
    5779–80 ¶¶ 390–91, 5785–86 ¶ 398, 5787 ¶ 401.
    As an initial matter, there is no dispute about the
    “capability” of mobile broadband subscribers to
    “communicate to” other mobile broadband users. As the
    Commission explained in the Order—and as is undisputed—
    “mobile broadband . . . gives its users the capability to send
    and receive communications from all other users of the
    Internet.” 
    Id.
     at 5785 ¶ 398. The remaining issue for the
    Commission therefore concerned communications from
    mobile broadband users to telephone users: whether mobile
    broadband “gives subscribers the capability to communicate
    to” users via telephone numbers. 
    47 C.F.R. § 20.3
    . The
    Commission concluded that it does.
    Specifically, the Commission determined that mobile
    broadband gives a subscriber the capability to communicate
    with a telephone user through the use of Voice over Internet
    Protocol (VoIP) applications. See 2015 Open Internet Order,
    30 FCC Rcd. at 5786–87 ¶¶ 400–01. (Skype, FaceTime, and
    Google Voice and Hangouts are popular examples of VoIP
    applications.) VoIP technology enables a mobile broadband
    user to send a voice call from her IP address to the recipient’s
    telephone number. As a result, a mobile broadband user with
    a VoIP application on her tablet can call her friend’s home
    phone number even if the caller’s tablet lacks cellular voice
    access (and thus has no assigned telephone number). When
    she dials her friend’s telephone number, the VoIP service
    sends the call from her tablet’s IP address over the mobile
    broadband network to connect to the telephone network and,
    ultimately, to her friend’s home phone. As such, mobile
    broadband, through VoIP, “gives subscribers the capability to
    communicate to” telephone users. 
    47 C.F.R. § 20.3
    .
    68
    In 2007, when the Commission first considered the
    proper classification of then-nascent mobile broadband, the
    Commission had a different understanding about the
    relationship between mobile broadband and VoIP. At that
    time, the Commission considered VoIP applications to be a
    separate, non-integrated service, such that VoIP’s ability to
    connect internet and telephone users was not thought to
    render mobile broadband an interconnected service. See 2007
    Wireless Order, 22 FCC Rcd. at 5917–18 ¶ 45. But when the
    Commission revisited the issue nearly a decade later in the
    Order we now review, the Commission found that its
    “previous determination about the relationship between
    mobile broadband Internet access and VoIP applications in
    the context of section 332 no longer accurately reflects the
    current technological landscape.” 2015 Open Internet Order,
    30 FCC Rcd. at 5787 ¶ 401. In particular, it concluded that
    VoIP applications now function as an integrated aspect of
    mobile broadband, rather than as a functionally distinct,
    separate service. The Commission therefore found that
    mobile broadband “today, through the use of VoIP, . . . gives
    subscribers the capability to communicate with all NANP
    endpoints.” 
    Id.
    In reaching that conclusion, the Commission emphasized
    that “changes in the marketplace . . . highlight the
    convergence between mobile voice and data networks that has
    occurred since the Commission first addressed the
    classification of mobile broadband Internet access in 2007.”
    
    Id.
     The record before the Commission substantially supports
    that understanding, as well as the associated finding that the
    relationship between VoIP applications and mobile broadband
    today significantly differs from that of 2007. For instance, in
    2007, Apple’s iPhone—the only device at the time even
    “resembling a modern smart phone”—had just been released
    and was available through only one mobile carrier. Letter
    69
    from Harold Feld, et al., Public Knowledge to Marlene H.
    Dortch, FCC, at 10, GN Dkt. Nos. 14-28 & 10-127 (Dec. 19,
    2014) (“Public Knowledge 12/19 Letter”). Commenters drew
    the Commission’s attention to its recognition in 2007 that
    “mobile broadband available with a standard mobile phone of
    the time ‘enable[d] users to access a limited selection of
    websites’ and primarily offered extremely limited
    functionality such as email.” 
    Id.
     (citing 2007 Wireless Order,
    22 FCC Rcd. at 5906 ¶ 11 & n.43). Because of those
    limitations, “[i]ndependent ‘app stores’ that allow for
    seamless downloading and integration of standalone
    applications [e.g., VoIP applications] into the customer’s
    handset did not exist” in 2007. 
    Id.
    The Commission also noted that, today, mobile
    broadband is dramatically faster: the average network
    connection speed “exploded” in just three years, going from
    an average connection speed of 709 kilobytes per second
    (kbps) in 2010 to an average speed of 2,058 kbps for all
    devices and 9,942 kbps for smartphones by 2013. 2015 Open
    Internet Order, 30 FCC Rcd. at 5636 ¶ 89 & n.170. Partly as
    a result, access to the internet and applications on one’s
    mobile phone is no longer confined to a small number of
    functions. Rather, “there has been substantial growth” even
    since 2010—far more so since 2007—“in the digital app
    economy . . . and VoIP” in particular. 
    Id.
     at 5626 ¶ 76.
    In addition, the Commission cited a letter which
    explained that, because VoIP applications (such as FaceTime
    on Apple devices and Google Hangouts on Android devices)
    now come “bundled with the primary operating systems
    available in every smartphone,” they are no longer “rare and
    clearly functionally distinct” as they were in 2007. Letter
    from Michael Calabrese, Open Technology Institute, et al., to
    Marlene H. Dortch, FCC, at 6, GN Dkt. Nos. 14-28 & 10-127
    70
    (Dec. 11, 2014) (“OTI 12/11 Letter”); see 2015 Open Internet
    Order, 30 FCC Rcd. at 5787 ¶ 401 n.1168. Any distinction
    between calls made with a device’s “native” dialing capacity
    and those made through VoIP thus has become “increasingly
    inapt.” OTI 12/11 Letter at 5; see Public Knowledge 12/19
    Letter at 10.
    The Commission accordingly found that “[t]oday, mobile
    VoIP . . . is among the increasing number of ways in which
    users communicate indiscriminately between NANP and IP
    endpoints on the public switched network.” 2015 Open
    Internet Order, 30 FCC Rcd. at 5787 ¶ 401; see Resp’ts’ Br.
    99 (relying on that finding). In light of those developments,
    the Commission reasonably determined that mobile
    broadband today is interconnected with the newly defined
    public switched network. It “gives subscribers the capability
    to communicate to . . . other users on the public switched
    network,” whether the recipient has an IP address, telephone
    number, or both. 
    47 C.F.R. § 20.3
    ; see 2015 Open Internet
    Order, 30 FCC Rcd. at 5779–80 ¶ 391, 5785–87 ¶¶ 398–401.
    In contending otherwise, mobile petitioners argue that
    mobile broadband itself is not “interconnected with the public
    switched network,” 
    47 U.S.C. § 332
    (d)(2), because mobile
    broadband does not allow subscribers to interconnect with
    telephone users unless subscribers take the step of using a
    VoIP application. Nothing in the statute, however, compels
    the Commission to draw a talismanic (and elusive) distinction
    between (i) mobile broadband alone enabling a connection,
    and (ii) mobile broadband enabling a connection through use
    of an adjunct application such as VoIP. To the contrary, the
    statute grants the Commission express authority to define
    “interconnected service.” 
    47 U.S.C. § 332
    (d)(2). And the
    Commission permissibly exercised that authority to determine
    that—in light of the increased availability, use, and
    71
    technological and functional integration of VoIP
    applications—mobile broadband should now be considered
    interconnected with the telephone network. Indeed, even for
    communications from one mobile broadband user to another,
    mobile broadband generally works in conjunction with a
    native or third-party application of some sort (e.g., an email
    application such as Gmail or a messaging application such as
    WhatsApp) to facilitate transmission of users’ messages. The
    conjunction of mobile broadband and VoIP to enable IP-to-
    telephone communications is no different.
    That is especially apparent in light of the Commission’s
    regulatory definition of “interconnected service.”        The
    regulation calls for assessing whether mobile broadband
    “gives subscribers the capability to communicate to”
    telephone users. 
    47 C.F.R. § 20.3
     (emphasis added). Mobile
    petitioners do not challenge the Commission’s understanding
    that a “capability to communicate” suffices to establish an
    interconnected service, and we see no ground for rejecting the
    Commission’s conclusion that mobile broadband gives
    subscribers the “capability to communicate to” telephone
    users through VoIP. And although the regulation also
    references “receiv[ing] communications from” others in the
    network, 
    id.,
     mobile petitioners also do not challenge the
    Commission’s understanding that the capability either to
    “communicate to or receive communication from” is enough,
    
    id.
     (emphasis added). Consequently, the capability of mobile
    broadband users “to communicate to” telephone users via
    VoIP suffices to render the network—and, most importantly,
    its users—“interconnected.”
    Mobile petitioners note what they perceive to be a
    separate problem associated with communications running in
    the reverse direction (i.e., the capability of mobile broadband
    users to “receive communications from” telephone users).
    72
    That ostensible problem pertains, not to mobile broadband
    service, but instead to mobile voice service. In particular,
    mobile petitioners argue that, if the public switched network
    can be defined to use both IP addresses and telephone
    numbers, mobile voice service would no longer qualify as an
    “interconnected service” because telephone users cannot
    establish a connection to IP users. The result, mobile
    petitioners submit, is that the one network everyone agrees
    was intended to qualify as a commercial mobile service—
    mobile voice—would necessarily become a private mobile
    service. We are unconvinced.
    As a starting point, the Commission’s Order takes up the
    proper classification of mobile broadband, not mobile voice.
    The Commission thus did not conduct a formal assessment of
    whether mobile voice would qualify as an interconnected
    service under the revised definition of public switched
    network. But were the Commission to address that issue in a
    future proceeding, it presumably would note that, regardless
    of whether mobile voice users can “communicate to” mobile
    broadband users from their telephones, they can “receive
    communication from” mobile broadband users through VoIP
    for the reasons already explained. 
    47 C.F.R. § 20.3
    . That
    capability would suffice to render mobile voice an
    “interconnected service” under the Commission’s regulatory
    definition of that term. 
    Id.
    Moreover, insofar as the Commission may be asked in
    the future to formally address whether mobile voice qualifies
    as an interconnected service, the Commission could assess at
    that time whether there exists the “capability” of
    communications in the reverse direction, i.e., the capability of
    mobile voice users to “communicate to” IP users from their
    telephones.     
    Id.
       We note that the Commission had
    information before it in this proceeding indicating that a
    73
    mobile broadband (or other computer) user can employ a
    service enabling her to receive telephone calls to her IP
    address. See Public Knowledge 12/19 Letter at 11 n.50
    (describing a television commercial demonstrating Apple’s
    Continuity service, which enables an iPhone 6 user with
    mobile voice service to call an iPad user with mobile
    broadband service); Use Continuity to connect your iPhone,
    iPad, iPod touch, and Mac, https://support.apple.com/en-us
    /HT204681 (last visited June 14, 2016) (“With Continuity,
    you can make and receive cellular phone calls from your iPad,
    iPod touch, or Mac when your iPhone is on the same Wi-Fi
    network.”); see also Receive Google Voice calls with
    Hangouts,         https://support.google.com/hangouts/answer
    /6079064 (last visited June 14, 2016) (describing how the
    “Google Voice” and “Hangouts” services allow mobile
    broadband users to receive calls from telephone users); What
    is a Skype Number?, https://support.skype.com/en/faq/FA331
    /what-is-a-skype-number (last visited June 14, 2016)
    (describing how a “Skype Number” enables mobile
    broadband users to receive calls from telephone users).
    For those reasons, we reject mobile petitioners’ argument
    that the Commission’s classification of mobile broadband as
    an “interconnected service” is impermissible because of its
    supposed implications for the classification of mobile voice.
    Rather, the Commission permissibly found that mobile
    broadband now qualifies as interconnected because it gives
    subscribers the ability to communicate to all users of the
    newly defined public switched network. In the words of the
    Commission: “mobile broadband Internet access service
    today, through the use of VoIP, messaging, and similar
    applications, effectively gives subscribers the capability to
    communicate with all NANP endpoints as well as with all
    users of the Internet.” 2015 Open Internet Order, 30 FCC
    Rcd. at 5787 ¶ 401.
    74
    Finally, the finding that mobile broadband today “gives
    subscribers the capability to communicate with all NANP
    endpoints,” 
    id.
     (emphasis added), confirms the immateriality
    of the Commission’s removal of the word “all” from its
    regulatory definition of “interconnected service.”           As
    mentioned earlier, that regulation, until the Order, defined
    interconnected service as a service “that gives subscribers the
    capability to communicate to or receive communication from
    all other users on the public switched network.” 
    47 C.F.R. § 20.3
     (prior version effective through June 11, 2015)
    (emphasis added). In the updated definition, the Commission
    left that language unchanged except that it removed the word
    “all.” See 
    47 C.F.R. § 20.3
     (current version effective June 12,
    2015). Mobile petitioners attach great significance to the
    removal of “all,” assuming that the change enabled the
    Commission to find mobile broadband to be an
    “interconnected service” even though, according to mobile
    petitioners, broadband users have no capability to
    communicate with telephone users. By excising the word
    “all,” mobile petitioners assert, the Commission could find
    that mobile broadband is an interconnected service based on
    the ability of users to communicate only with some in the
    network (fellow broadband users) notwithstanding the lack of
    any capability to communicate with others in the network
    (telephone users). Absent the latter ability, mobile petitioners
    argue, mobile broadband cannot actually be considered
    “interconnected” with the telephone network.
    Mobile petitioners’ argument rests on a mistaken
    understanding of the Commission’s actions. The Commission
    did not rest its finding that mobile broadband is an
    “interconnected service” solely on an assumption that it
    would be enough for broadband subscribers to be able to
    communicate with some in the network (only fellow IP users),
    even if there were no capability at all to communicate with
    75
    others (telephone users). To the contrary, the Commission, as
    explained, found that mobile broadband—through VoIP—
    “gives subscribers the ability to communicate with all NANP
    endpoints as well as with all users of the Internet.” 2015
    Open Internet Order, 30 FCC Rcd. at 5787 ¶ 401 (emphasis
    added). Once we accept that finding, as we have, we need not
    consider petitioners’ argument challenging what the
    Commission characterizes as merely a “conforming” change
    with no independent substantive effect. See 
    id.
     at 5787–88
    ¶ 402 & n.1175. (Specifically, the Commission notes that the
    removal of “all” was meant to reiterate a carve-out that has
    always existed in the regulation: another part of the definition
    of “interconnected service” establishes that a service qualifies
    as “interconnected” even if it “restricts access in certain
    limited ways,” such as a service that blocks access to 900
    numbers. 
    Id.
     (quoting 
    47 C.F.R. § 20.3
    ); 
    id.
     at 5787 ¶ 402
    n.1172.)
    In the end, then, the removal of “all” is of no
    consequence to the Commission’s rationale for finding that
    mobile broadband constitutes an “interconnected service.”
    Mobile broadband, the Commission reasonably concluded,
    gives users the capability to communicate to all other users in
    the newly defined public switched network, whether users
    with an IP address, users with a telephone number, or users
    with both. See 
    id.
     at 5787 ¶ 401. Because mobile broadband
    thus can be considered an interconnected service, the
    Commission acted permissibly in reclassifying mobile
    broadband as a commercial mobile service subject to common
    carrier regulation, rather than a private mobile service
    immune from such regulation.
    3.
    Mobile petitioners also argue that the Commission has
    failed to “point to any change in the technology or
    76
    functionality of mobile broadband” sufficient to justify
    reclassifying mobile broadband as a commercial mobile
    service. US Telecom Pet’rs’ Br. 68. This argument fares no
    better in the mobile context than it did in the Title II
    reclassification context. Even if the Commission had not
    demonstrated changed factual circumstances—which, as
    described above, we think it has—mobile petitioners’
    argument would fail because the Commission need only
    provide a “reasoned explanation” for departing from its prior
    findings. See Fox Television, 
    556 U.S. at
    515–16 (“[I]t is not
    that further justification is demanded by the mere fact of
    policy change[,] but that a reasoned explanation is needed for
    disregarding facts and circumstances that underlay . . . the
    prior policy.”). It has done so here.
    4.
    Finally, we agree with the Commission that the need to
    avoid a statutory contradiction in the treatment of mobile
    broadband provides further support for its reclassification as a
    commercial mobile service. Each of the two statutory
    schemes covering mobile broadband requires classifying a
    service in a particular way before it can be subject to common
    carrier treatment. Under Title II, broadband must be
    classified as a “telecommunications service.” Under Title III,
    mobile broadband must be classified as a “commercial mobile
    service.” Because the two classifications do not automatically
    move in tandem, the Commission must make two distinct
    classification decisions. To avoid the contradictory result of
    classifying mobile broadband providers as common carriers
    under Title II while rendering them immune from common
    carrier treatment under Title III, the Commission, upon
    reclassifying broadband generally—including mobile—as a
    telecommunications service, reclassified mobile broadband as
    a commercial mobile service. See 2015 Open Internet Order
    at 5788 ¶ 403.
    77
    Avoiding that statutory contradiction not only assures
    consistent regulatory treatment of mobile broadband across
    Titles II and III, but it also assures consistent regulatory
    treatment of mobile broadband and fixed broadband, in
    furtherance of the Commission’s objective that “[b]roadband
    users should be able to expect that they will be entitled to the
    same Internet openness protections no matter what technology
    they use to access the Internet.” 2015 Open Internet Order,
    30 FCC Rcd. at 5638 ¶ 92. When consumers use a mobile
    device (such as a tablet or smartphone) to access the internet,
    they may establish a connection either through mobile
    broadband or through a Wi-Fi connection at home, in the
    office, or at an airport or coffee shop. Such Wi-Fi
    connections originate from a landline broadband connection,
    which is now a telecommunications service regulated as a
    common carrier under Title II. If a consumer loses her Wi-Fi
    connection for some reason while accessing the internet—
    including, for instance, if she walks out the front door of her
    house, and thus out of Wi-Fi range—her device could switch
    automatically from a Wi-Fi connection to a mobile broadband
    connection. If mobile broadband were classified as a private
    mobile service, her ongoing session would no longer be
    subject to common carrier treatment. In that sense, her
    mobile device could be subject to entirely different regulatory
    rules depending on how it happens to be connected to the
    internet at any particular moment—which could change from
    one minute to the next, potentially even without her
    awareness.
    The Commission’s decision to reclassify mobile
    broadband as a commercial mobile service prevents that
    counterintuitive outcome by assuring consistent regulatory
    treatment of fixed and mobile broadband. By contrast, if
    mobile broadband—despite the public’s “rapidly growing and
    virtually universal use” of the service today, 
    id.
     at 5786
    78
    ¶ 399—must still be classified as a “private” mobile service,
    broadband users may no longer experience “the same Internet
    openness protections no matter what technology they use to
    access the Internet.” 
    Id.
     at 5638 ¶ 92.
    C.
    Mobile petitioners also challenge the sufficiency of the
    Commission’s notice, particularly with respect to its
    redefinition of the public switched network as well as its
    removal of the word “all” from the definition of
    interconnected service. As noted above, the APA requires
    that an NPRM “include . . . either the terms or substance of
    the proposed rule or a description of the subjects and issues
    involved.” 
    5 U.S.C. § 553
    (b). But the APA also requires us
    to take “due account” of “the rule of prejudicial error.” 
    Id.
    § 706.
    A deficiency of notice is harmless if the challengers had
    actual notice of the final rule, Small Refiner Lead Phase-
    Down Task Force v. EPA, 
    705 F.2d 506
    , 549 (D.C. Cir.
    1983), or if they cannot show prejudice in the form of
    arguments they would have presented to the agency if given a
    chance, Owner-Operator Independent Drivers Ass’n v.
    Federal Motor Carrier Safety Administration, 
    494 F.3d 188
    ,
    202 (D.C. Cir. 2007). Both circumstances are present here,
    and each independently supports our conclusion that any lack
    of notice was ultimately harmless. As such, we need not
    decide whether the Commission gave adequate notice of its
    redefinition of the public switched network in the NPRM.
    As mobile petitioners acknowledge, Vonage raised the
    idea of redefining the public switched network in its
    comments, pointing out the Commission’s “authority to
    interpret the key terms in th[e] definition [of commercial
    mobile service], including ‘interconnected’ and ‘public
    79
    switched network.’” Vonage Holdings Corp. Comments at
    43, GN Dkt. Nos. 14-28 & 10-127 (July 18, 2014). Mobile
    petitioner CTIA responded to that point in its reply comments,
    disputing Vonage’s underlying assumption that mobile
    broadband users can connect with all telephone users, see
    CTIA Reply Comments at 45, GN Dkt. Nos. 14-28 & 10-127
    (Sept. 15, 2014), thereby recognizing that the definition of
    public switched network was in play.
    In addition, over the course of several months before
    finalization and release of the Order, mobile petitioners (and
    others) submitted multiple letters to the Commission
    concerning the potential for redefining the public switched
    network. See, e.g., Letter from Henry G. Hultquist, AT&T, to
    Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127

    We have previously charged petitioners challenging an
    agency rule with actual notice based on letters like those
    submitted by mobile petitioners. See Sierra Club v. Costle,
    
    657 F.2d 298
    , 355 (D.C. Cir. 1981). But we have even more
    evidence of actual notice here. Mobile petitioners note in
    their letters that, in meetings with the Commission, they
    discussed the substance of their arguments here, including
    80
    issues surrounding the redefinition of public switched
    network. See AT&T 2/13 Letter at 1 (noting a meeting with
    representatives from Commissioners O’Rielly’s and Pai’s
    offices on February 11, 2015); CTIA 1/14 Letter at 1 (noting a
    meeting with representatives from Commissioner Pai’s office
    on January 12, 2015); CTIA 12/22 Letter at 1 (noting a
    meeting with representatives from the Commission’s General
    Counsel’s office and representatives from the Wireless
    Telecommunications Bureau on December 18, 2014); CTIA
    10/17 Letter at 1 (noting a meeting with the Commission’s
    General Counsel and a representative from the Wireline
    Competition Bureau on October 15, 2014). Thus, even if the
    redefinition of public switched network was a “novel
    proposal” by Vonage during the comment period, it is clear
    from mobile petitioners’ own letters that they had actual
    notice that the Commission was considering adoption of that
    proposal. See National Mining Ass’n v. Mine Safety & Health
    Administration, 
    116 F.3d 520
    , 531–32 (D.C. Cir. 1997).
    In addition, in those letters, letters from others supporting
    mobile petitioners’ views, and responsive letters from groups
    like New America’s Open Technology Institute and Public
    Knowledge, mobile petitioners engaged in a detailed,
    substantive back-and-forth about the precise issues they
    challenge here. Reclassification of mobile broadband and
    redefinition of the public switched network were the focal
    points of that discussion, in which petitioners exchanged
    arguments about technology and policy with the groups
    supporting a broader definition of the public switched
    network. See Letters from CTIA and AT&T, supra; Letter
    from Michael Calabrese, Open Technology Institute, to
    Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127 (Jan.
    27, 2015); Letter from Harold Feld, Public Knowledge, to
    Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127 (Jan.
    15, 2015); Letter from William H. Johnson, Verizon, to
    81
    Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127
    (Dec. 24, 2014); Public Knowledge 12/19 Letter; Letter from
    Michael E. Glover, Verizon, to Marlene H. Dortch, FCC, GN
    Dkt. Nos. 14-28 & 10-127 (Oct. 29, 2014); OTI 12/11 Letter;
    Letter from William H. Johnson, Verizon, to Marlene H.
    Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127 (Oct. 17, 2014).
    In those exchanges, mobile petitioners raised and fiercely
    debated all of the same arguments they now raise before us,
    thus demonstrating not only the presence of actual notice, but
    also the absence of new arguments they might present to the
    Commission on remand.          Indeed, when asked at oral
    argument, mobile petitioners could not list any new argument
    on the issue of the redefinition of public switched network.
    See Oral Arg. Tr. 74–79, 84–87.
    Mobile petitioners also allege that the Commission gave
    inadequate notice of the removal of “all” from the definition
    of interconnected service. Any such failure, however, was
    also harmless.      As noted above, not only does the
    Commission claim that the removal of “all” was
    inconsequential to the regulation, but that adjustment also has
    no bearing on our decision to uphold the Commission’s
    reclassification decision.        We would uphold the
    Commission’s decision regardless of whether the Commission
    validly removed “all” from the definition of “interconnected
    service.” Mobile petitioners thus cannot show prejudice from
    any lack of notice. See Steel Manufacturers Ass’n v. EPA, 
    27 F.3d 642
    , 649 (D.C. Cir. 1994) (explaining that inability to
    comment on one rationale for rule was harmless when agency
    had “adequate and independent grounds” for rule).
    Mobile petitioners, for those reasons, fail to show the
    prejudice required by the APA to succeed on their arguments
    of insufficient notice. We therefore reject their challenges.
    82
    V.
    Having upheld the Commission’s reclassification of
    broadband services, both fixed and mobile, we consider next
    Full Service Network’s challenges to the Commission’s
    decision to forbear from applying portions of the
    Communications Act to those services. Section 10 of the
    Communications Act provides that the Commission “shall
    forbear from applying any regulation or any provision” of the
    Communications Act to a telecommunications service or
    carrier if three criteria are satisfied: (1) “enforcement of such
    regulation or provision is not necessary to ensure that” the
    carrier’s practices “are just and reasonable and are not
    unjustly or unreasonably discriminatory,” 
    47 U.S.C. § 160
    (a)(1); (2) “enforcement of such regulation or provision
    is not necessary for the protection of consumers,” 
    id.
    § 160(a)(2); and (3) “forbearance from applying such
    provision or regulation is consistent with the public interest,”
    id. § 160(a)(3). Under the third criterion, “the Commission
    shall consider whether forbearance . . . will promote
    competitive market conditions, including the extent to which
    such forbearance will enhance competition among providers
    of telecommunications services.” Id. § 160(b). Thus, section
    10 imposes a mandatory obligation upon the Commission to
    forbear when it finds these conditions are met.
    Section 10(c) gives any carrier the right to “submit a
    petition to the Commission requesting” forbearance. Id.
    § 160(c). In regulations issued pursuant to section 10(c), the
    Commission requires “petitions for forbearance” to include a
    “[d]escription of relief sought,” make a prima facie case that
    the statutory criteria for forbearance are satisfied, identify any
    related matters, and provide any necessary evidence. 
    47 C.F.R. § 1.54
    .
    83
    In the Order, the Commission decided to forbear from
    numerous provisions of the Communications Act. 2015 Open
    Internet Order, 30 FCC Rcd. at 5616 ¶ 51. Full Service
    Network raises both procedural and substantive challenges to
    the Commission’s forbearance decision. None succeeds.
    A.
    Full Service Network first argues that the Commission
    should have followed its regulatory requirements governing
    forbearance petitions even though it forbore of its own accord.
    In the Order, the Commission rejected this contention, stating
    that “[b]ecause the Commission is forbearing on its own
    motion, it is not governed by its procedural rules insofar as
    they apply, by their terms, to section 10(c) petitions for
    forbearance.” 
    Id.
     at 5806 ¶ 438.
    “[W]e review an agency’s interpretation of its own
    regulations with ‘substantial deference.’” In re Sealed Case,
    
    237 F.3d 657
    , 667 (D.C. Cir. 2001) (quoting Thomas
    Jefferson University v. Shalala, 
    512 U.S. 504
    , 512 (1994)).
    The agency’s interpretation “will prevail unless it is ‘plainly
    erroneous or inconsistent’ with the plain terms of the disputed
    regulation.” Everett v. United States, 
    158 F.3d 1364
    , 1367
    (D.C. Cir. 1998) (quoting Auer v. Robbins, 
    519 U.S. 452
    , 461
    (1997)).
    The Commission’s interpretation of its regulations easily
    satisfies this standard. By their own terms, the regulations
    apply to “petitions for forbearance,” and nowhere say
    anything about what happens when, as here, the Commission
    decides to forbear without receiving a petition. See 
    47 C.F.R. § 1.54
    . To the extent this silence renders the regulations
    ambiguous in the circumstance before us, the Commission’s
    interpretation is hardly “plainly erroneous.” Everett, 
    158 F.3d at 1367
     (internal quotation marks omitted).
    84
    Full Service Network also contends that the NPRM
    violated the APA’s notice requirement because it nowhere
    identified the rules from which the Commission later decided
    to forbear. The NPRM, however, listed the provisions from
    which the Commission likely would not forbear, which by
    necessary implication indicated that the Commission would
    consider forbearing from all others. The NPRM did so by
    citing a 2010 notice of inquiry, in which the Commission had
    contemplated that, if it were to classify the Internet
    connectivity component of broadband Internet access
    service, it would forbear from applying all but a
    handful of core statutory provisions—sections 201,
    202, 208, and 254—to the service. In addition, the
    Commission identified sections 222 and 255 as
    provisions that could be excluded from forbearance,
    noting that they have attracted longstanding and
    broad support in the broadband context.
    NPRM, 29 FCC Rcd. at 5616 ¶ 154 (footnotes and internal
    quotation marks omitted). The NPRM sought “further and
    updated comment” on that course of action. 
    Id.
     Thus, Full
    Service Network “should have anticipated that” the
    Commission would consider forbearing from all remaining
    Title II provisions. Covad Communications Co., 
    450 F.3d at 548
    . Indeed, Full Service Network anticipated that the
    Commission would do just that. In its comments, Full Service
    Network argued that the Commission should not forbear from
    the provisions at issue here, thus demonstrating that it had no
    trouble     “comment[ing]        meaningfully,”     Honeywell
    International, Inc., 
    372 F.3d at 445
    . See Letter from Earl W.
    Comstock, Counsel for Full Service Network and
    TruConnect, to Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28
    & 10-127 (Feb. 20, 2015); Letter from Earl W. Comstock,
    Counsel for Full Service Network and TruConnect, to
    85
    Marlene H. Dortch, FCC, GN Dkt. Nos. 14-28 & 10-127, at 1
    (Feb. 3, 2015).
    B.
    Full Service Network contends that the Commission
    acted arbitrarily and capriciously in forbearing from the
    mandatory network connection and facilities unbundling
    requirements contained in sections 251 and 252. As relevant
    here, section 251 requires telecommunications carriers “to
    interconnect directly or indirectly” with other carriers and
    prohibits them from “impos[ing] unreasonable or
    discriminatory conditions or limitations on[] the resale
    of . . . telecommunications services.” 
    47 U.S.C. § 251
    (a)(1),
    (b)(1). “Incumbent local exchange carrier[s],” meaning
    carriers who “provided telephone exchange service” in a
    particular area as of the effective date of the
    Telecommunications Act, must provide nondiscriminatory
    access to their existing networks and unbundled access to
    network elements in order to allow service-level competition
    through resale. 
    Id.
     § 251(c), (h)(1). Section 252 sets
    standards for contracts that implement section 251
    obligations.
    Full Service Network first argues that section 10(a)(3)’s
    public interest determination “must be made for each
    regulation, provision and market . . . using the definition and
    context of that provision in the [Communications] Act.” Full
    Service Network Pet’rs’ Br. 14–15 (emphasis omitted).
    Because section 251 “applies to ‘local exchange carriers,’”
    Full Service Network contends, “the geographic market, as
    the name implies and the definition in the [Communications]
    Act confirms, is local and not national.” Id. at 15 (emphasis
    omitted) (quoting 
    47 U.S.C. § 251
    ).
    86
    Our decision in EarthLink, Inc. v. FCC, 
    462 F.3d 1
    ,
    forecloses this argument. There, EarthLink made a similar
    argument—that the inclusion of the phrase “geographic
    markets” in section 10 meant that the Commission could not
    “forbear on a nationwide basis” from separate unbundling
    requirements in section 271 “without considering more
    localized regions individually.” 
    Id. at 8
    . Rejecting this
    argument, we focused on the language of section 10, and held
    that “[o]n its face, the statute imposes no particular mode of
    market analysis or level of geographic rigor.” 
    Id.
     Rather,
    “the language simply contemplates that the FCC might
    sometimes forbear in a subset of a carrier’s markets; it is
    silent about how to determine when such partial relief is
    appropriate.” 
    Id.
     For the same reason, Full Service Network
    cannot rope section 251’s requirements into the
    Commission’s section 10 analysis.
    Full Service Network’s argument is also inconsistent with
    our decision in Verizon Telephone Cos. v. FCC, 
    570 F.3d 294
    (D.C. Cir. 2009). There, Verizon sought forbearance from
    section 251 in some of its telephone-service markets. 
    Id. at 299
    . The Commission denied Verizon’s petition, finding
    insufficient evidence of facilities-based competition to render
    the provision’s application unnecessary to protect the interests
    of consumers under section 10(a)(2) and to satisfy section
    10(a)(3)’s public-interest requirement. 
    Id.
     Challenging that
    decision, Verizon argued that the Commission’s forbearance
    decision was incompatible with the text of section 251
    because section 251 required the Commission to find that lack
    of access would “‘impair the ability of the
    telecommunications          carrier   seeking     access      to
    provide . . . service[],’” which the Commission had not done.
    
    Id. at 300
     (omission and alteration in original) (quoting 
    47 U.S.C. § 251
    ). We rejected this argument, explaining that
    “[t]he dispute before this court . . . concerns whether the
    87
    statutory text of § 10—not § 251—contradicts the FCC’s
    interpretation.” Id. We found reasonable the Commission’s
    conclusion that its section 10 analysis did not need to
    incorporate any statutory requirement arising from section
    251. Id. at 300–01. We do so again here.
    Full Service Network next challenges the Commission’s
    finding that “the availability of other protections adequately
    addresses commenters’ concerns about forbearance from the
    interconnection provisions under the section 251/252
    framework.” 2015 Open Internet Order, 30 FCC Rcd. at
    5849–50 ¶ 513 (footnote omitted). Specifically, Full Service
    Network attacks the Commission’s determination that section
    201 gives it sufficient authority to ensure that broadband
    networks connect to one another for the mutual exchange of
    traffic. Section 201 requires “every common carrier engaged
    in interstate or foreign communication by wire or radio to
    furnish such communication service upon reasonable request
    therefor” and, upon an order of the Commission, “to establish
    physical connections with other carriers, to establish through
    routes and charges applicable thereto and the divisions of
    such charges, and to establish and provide facilities and
    regulations for operating such through routes.” 
    47 U.S.C. § 201
    (a).     “All charges, practices, classifications, and
    regulations for and in connection with such communication
    service, shall be just and reasonable . . . .” 
    Id.
     § 201(b).
    Section 251 includes a savings provision that “[n]othing in
    this section shall be construed to limit or otherwise affect the
    Commission’s authority under section 201.” Id. § 251(i).
    Full Service Network first contends that the
    Commission’s authority under section 201 does not extend to
    physical co-location, under which local exchange carriers
    must allow third-party providers to physically locate cables on
    their property in furtherance of network connections. In
    88
    support, Full Service Network relies on our decision in Bell
    Atlantic Telephone Cos. v. FCC, 
    24 F.3d 1441
     (D.C. Cir.
    1994), in which we refused to uphold under section 201 a
    Commission rule requiring physical co-location. The rule, we
    reasoned, would unnecessarily raise Takings Clause issues
    because the Commission could use virtual co-location, where
    local exchange carriers maintain equipment that third-party
    providers can use, to implement section 201’s “physical
    connection” requirement without raising constitutional issues.
    
    Id. at 1446
    . So while Full Service Network is correct that Bell
    Atlantic imposes one limit on the Commission’s reach under
    section 201, that case also demonstrates that the Commission
    retains authority to regulate network connections under that
    section.
    Next, Full Service Network argues that section 152(b),
    which “prevent[s] the Commission from taking intrastate
    action solely because it further[s] an interstate goal,” AT&T
    Corp. v. Iowa Utilities Board, 
    525 U.S. 366
    , 381 (1999),
    prohibits the Commission from “us[ing] its interstate
    authority under [section] 201 to regulate broadband Internet
    access service that is an intrastate ‘telephone exchange
    service’ under the [Communications] Act,” Full Service
    Network Pet’rs’ Br. 17 (emphasis omitted) (quoting 
    47 U.S.C. § 153
    (54)).      According to Full Service Network, the
    Commission erred by refusing to determine whether
    broadband service qualifies as a “telephone exchange service”
    because that definition would prevent the Commission from
    classifying the internet as jurisdictionally interstate.
    In the Order, the Commission “reaffirm[ed] [its]
    longstanding conclusion” that broadband service falls within
    its jurisdiction as an interstate service. 2015 Open Internet
    Order, 30 FCC Rcd. at 5803 ¶ 431; see Cable Broadband
    Order, 17 FCC Rcd. at 4832 ¶ 59; In re GTE Telephone
    89
    Operating Cos. GTOC Tariff No. 1, GTOC Transmittal No.
    1148, 13 FCC Rcd. 22,466, 22,474–83 ¶¶ 16–32 (1998).
    “The Internet’s inherently global and open architecture,” the
    Commission reasoned, “mak[es] end-to-end jurisdictional
    analysis extremely difficult—if not impossible—when the
    services at issue involve the Internet.” 2015 Open Internet
    Order, 30 FCC Rcd. at 5803 ¶ 431 (internal quotation marks
    omitted). The Commission also determined that because it
    had found the section 10 criteria met as to section 251, it had
    no reason to “resolve whether broadband Internet access
    service could constitute ‘telephone exchange service’” under
    section 251. 
    Id.
     at 5851 ¶ 513 n.1575.
    We approved the Commission’s jurisdictional approach
    in Core Communications, Inc. v. FCC, 
    592 F.3d 139
    , 144
    (D.C. Cir. 2010). Although the petitioners in that case never
    challenged the general framework of the Commission’s “end-
    to-end analysis, . . . under which the classification of a
    communication as local or interstate turns on whether its
    origin and destination are in the same state,” 
    id. at 142
    , we
    recognized that
    [d]ial-up internet traffic is special because it involves
    interstate communications that are delivered through
    local calls; it thus simultaneously implicates the
    regimes of both § 201 and of §§ 251–252. Neither
    regime is a subset of the other. They intersect, and
    dial-up internet traffic falls within that intersection.
    Given this overlap, § 251(i)’s specific saving of the
    Commission’s authority under § 201 against any
    negative implications from § 251 renders the
    Commission’s reading of the provisions at least
    reasonable.
    90
    Id.; see also National Ass’n of Regulatory Utility
    Commissioners v. FCC, 
    746 F.2d 1492
    , 1501 (D.C. Cir. 1984)
    (“[W]e have concluded that the FCC has broad power to
    regulate physically intrastate facilities where they are used for
    interstate communication.”).             To be sure, Core
    Communications concerned dial-up internet access, but
    because broadband involves a similar mix of local facilities
    and interstate information networks, we see no meaningful
    distinction between the interpretation approved in Core
    Communications and the one the Commission offered here.
    Nor do we see any reason to obligate the Commission to
    determine the legal status of each underlying “hypothetical
    regulatory obligation[]” that could result from any particular
    Communications Act provision prior to undertaking the
    section 10 forbearance analysis. AT & T Inc. v. FCC, 
    452 F.3d 830
    , 836–37 (D.C. Cir. 2006).
    Full Service Network’s final argument is not especially
    clear. It appears to claim that the Commission provided
    inadequate support for its forbearance decision. Pointing out
    that in prior proceedings the Commission had found that
    mandatory unbundling in the telephone context would
    promote competition and emphasizing that Congress passed
    section 251 to foster competition, Full Service Network
    argues that “[section 10] surely requires more to support
    forbearance than an assertion by the FCC that ‘other
    authorities’ are adequate and the public interest will be better
    served by enhancing the agency’s discretion.” Full Service
    Network Pet’rs’ Br. 20.
    In evaluating Full Service Network’s argument that the
    Commission failed to provide adequate justification for its
    forbearance decision, we are guided by “the traditional
    ‘arbitrary    and      capricious’   standard,”    Cellular
    Telecommunications & Internet Ass’n v. FCC, 
    330 F.3d 502
    ,
    91
    507–08 (D.C. Cir. 2003), under which “the agency must
    examine the relevant data and articulate a satisfactory
    explanation for its action including a rational connection
    between the facts found and the choice made,” State Farm,
    
    463 U.S. at 43
     (internal quotation marks omitted). We have
    applied this standard to section 10 forbearance decisions and
    have “consistently deferred to [such decisions], except in
    cases where the Commission deviated without explanation
    from its past decisions or did not discuss section 10’s criteria
    at all.” Verizon v. FCC, 
    770 F.3d 961
    , 969 (D.C. Cir. 2014)
    (internal citations omitted).
    In the Order, the Commission identified two bases for
    forbearing from sections 251 and 252. First, it considered
    evidence from commenters who argued that “last-mile
    unbundling requirements . . . led to depressed investment in
    the European broadband marketplace.” 2015 Open Internet
    Order, 30 FCC Rcd. at 5796 ¶ 417. Those commenters
    identified several studies suggesting that mandatory
    unbundling had reduced investment in broadband
    infrastructure in Europe relative to the United States. See

    Letter from Christopher S. Yoo to Marlene H. Dortch, FCC,
    GN Dkt. Nos. 14-28, 10-127, 09-191 (June 10, 2014). The
    Commission reasoned that its decision to forbear from section
    251’s unbundling requirement, in combination with regulation
    under other provisions of Title II, would avoid similar
    problems and encourage further deployment because the
    scheme “establishes the regulatory predictability needed by
    92
    all sectors of the Internet industry to facilitate prudent
    business planning, without imposing undue burdens that
    might interfere with entrepreneurial opportunities.” 2015
    Open Internet Order, 30 FCC Rcd. at 5796 ¶ 417.
    The Commission also identified “numerous concerns
    about the burdens—or, at a minimum, regulatory
    uncertainty—that would be fostered by a sudden, substantial
    expansion of the actual or potential regulatory requirements
    and obligations relative to the status quo from the near-term
    past,” in which many broadband providers were not subject to
    any aspect of Title II. 
    Id.
     at 5839 ¶ 495. In reaching this
    conclusion, the Commission drew from its experience with
    the mobile voice industry, which “thrived under a market-
    based Title II regime” that included significant forbearance,
    “demonstrating that robust investment is not inconsistent with
    a light-touch Title II regime.” 
    Id.
     at 5799–800 ¶ 423.
    Full Service Network argues that the Commission’s
    “prior       predictions     of      ‘vibrant      intermodal
    competition’ . . . ‘cannot be reconciled with marketplace
    realities.’” Full Service Network Pet’rs’ Reply Br. 10
    (quoting 2015 Open Internet Order, 30 FCC Rcd. at 5743
    ¶ 330). As we noted above, however, “[a]n agency’s
    predictive judgments about areas that are within the agency’s
    field of discretion and expertise are entitled to particularly
    deferential review, as long as they are reasonable.”
    EarthLink, 
    462 F.3d at 12
     (internal quotation marks omitted).
    In this case, the Commission’s predictive judgments about the
    effect mandatory unbundling would have on broadband
    deployment were perfectly reasonable and supported by
    record evidence. Multiple studies provided evidence that
    mandatory unbundling harmed investment in Europe. Such
    evidence, combined with the Commission’s experience in
    using a “light touch” regulatory program for mobile voice,
    93
    demonstrates “a rational connection between the facts found
    and the choice made” to forbear from applying sections 251
    and 252. State Farm, 
    463 U.S. at 43
     (internal quotation
    marks omitted). The APA demands nothing more.
    The partial dissent agrees with much of this, but
    nonetheless believes that the Commission acted arbitrarily
    and capriciously by “attempt[ing] to have it both ways” when
    it found a lack of competition in its reclassification decision,
    but simultaneously found adequate competition to justify
    forbearance. Concurring & Dissenting Op. at 67. The partial
    dissent also believes that the Commission’s competition
    analysis was contrary to its own precedent. 
    Id. at 66
    .
    Notably, however, and despite the partial dissent’s assertion,
    see 
    id.
     at 60–61, Full Service Network has never claimed that
    the Commission misapplied any of the section 10(a) factors,
    failed to analyze competitive effect as required by section
    10(b), or acted contrary to its forbearance precedent. Indeed,
    when pressed at oral argument, Full Service Network
    disclaimed any intent to make these arguments. Oral Arg. Tr.
    139–40. Full Service Network’s argument regarding the
    Commission’s competition analysis was confined to its
    contention that section 251’s focus on local competition
    required the Commission to perform a local market analysis
    as part of its forbearance inquiry. As the partial dissent
    acknowledges, EarthLink “fully supports the Commission” on
    that score. Concurring & Dissenting Op. at 68. According to
    the partial dissent, however, by citing section 10(b) in its
    brief, Full Service Network presented a broader challenge to
    the Commission’s competition analysis. 
    Id.
     at 60–61. But
    Full Service Network cited section 10(b) only once, and only
    in the context of its argument that the Commission “must
    evaluate each provision [under section 10] using the definition
    and context of that provision in the Act,” which, “[i]n the
    context of the local ‘connection link’ to the Internet that
    94
    phone      and     cable    company   broadband      service
    provides, . . . must be made on a local market-by-market
    basis.” Full Service Network Pet’rs’ Br. 15 (emphasis
    omitted). We have addressed that argument above, and Full
    Service Network makes no other section 10(b) argument.
    Because Full Service Network never presents in its briefs the
    arguments made by the partial dissent, those arguments lie
    outside the scope of our review.
    VI.
    We turn next to petitioners’ challenges to the particular
    rules adopted by the Commission. As noted earlier, the
    Commission promulgated five rules in the Order: rules
    banning (i) blocking, (ii) throttling, and (iii) paid
    prioritization, 2015 Open Internet Order, 30 FCC Rcd. at
    5647 ¶ 110; (iv) a General Conduct Rule, 
    id.
     at 5660 ¶ 136;
    and (v) an enhanced transparency rule, 
    id.
     at 5669–82 ¶¶ 154–
    85. Petitioners Alamo and Berninger (together, Alamo)
    challenge the anti-paid-prioritization rule as beyond the
    Commission’s authority. US Telecom challenges the General
    Conduct Rule as unconstitutionally vague. We reject both
    challenges.
    A.
    In its challenge to the anti-paid-prioritization rule,
    petitioner Alamo contends that, even with reclassification of
    broadband as a telecommunications service, the Commission
    lacks authority to promulgate such a rule under section
    201(b) of Title II and section 303(b) of Title III. The
    Commission, however, grounded the rules in “multiple,
    complementary sources of legal authority”—not only Titles II
    and III, but also section 706 of the Telecommunications Act
    of 1996 (now codified at 
    47 U.S.C. § 1302
    ). 
    Id.
     at 5720–21
    ¶¶ 273–74. As to section 706, this court concluded in Verizon
    95
    that it grants the Commission independent rulemaking
    authority. 740 F.3d at 635–42. Alamo nonetheless argues
    that the Commission lacks authority to promulgate rules under
    section 706. It rests that argument on a claim that this court’s
    contrary conclusion in Verizon was dicta.
    Alamo misreads Verizon. Our decision in that case
    considered three rules from the 2010 Open Internet Order: an
    anti-blocking rule, an anti-discrimination rule, and a
    transparency rule. See id. at 633. We determined that section
    706 vests the Commission “with affirmative authority to enact
    measures encouraging the deployment of broadband
    infrastructure” and that the Commission had “reasonably
    interpreted section 706 to empower it to promulgate rules
    governing broadband providers’ treatment of Internet traffic.”
    Id. at 628. In doing so, we also found that the Commission’s
    justification for those rules—“that they will preserve and
    facilitate the ‘virtuous circle’ of innovation that has driven the
    explosive growth of the Internet”—was reasonable and
    supported by substantial evidence. Id. We ultimately struck
    down the anti-blocking and anti-discrimination rules on the
    ground that they amounted to common carrier regulation
    without any accompanying determination that broadband
    providers should be regulated as common carriers. See id. at
    655–58. But we upheld the Commission’s transparency rule
    as a permissible and reasonable exercise of its section 706
    authority, one that did not improperly impose common carrier
    obligations on broadband providers. See id. at 659. Because
    our findings with regard to the Commission’s 706 authority
    were necessary to our decision to uphold the transparency
    rule, those findings cannot be dismissed as dicta. Seminole
    Tribe of Florida v. Florida, 
    517 U.S. 44
    , 67 (1996) (“When
    an opinion issues for the Court, it is not only the result but
    also those portions of the opinion necessary to that result by
    which we are bound.”). We note, moreover, that the separate
    96
    opinion concurring in part and dissenting in part agreed with
    the court’s conclusion as to the existence of rulemaking
    authority under section 706 and made no suggestion that the
    conclusion was mere dicta. See Verizon, 740 F.3d at 659–68
    (Silberman, J., concurring in part and dissenting in part).
    Alamo does not contend that the anti-paid-prioritization
    rule falls outside the scope of the Commission’s rulemaking
    authority under section 706 or is otherwise an improper
    exercise of that authority (if, as we held in Verizon and
    reiterate here, that authority exists in the first place). Alamo
    argues only that Verizon was wrong on the antecedent
    question of the Commission’s authority to promulgate rules
    under section 706 at all. Unfortunately for Alamo, Verizon
    established precedent on the existence of the Commission’s
    rulemaking authority under section 706 and thus controls our
    decision here. Consequently, we reject Alamo’s challenges to
    the Commission’s section 706 authority and to the anti-paid-
    prioritization rule.
    Our colleague picks up where Alamo leaves off, arguing
    that, even if Verizon’s conclusions about the existence of the
    Commission’s section 706 authority were not mere dicta,
    Verizon’s conclusions about the scope of that authority
    (including the permissibility of the Commission’s reliance on
    the “virtuous cycle” of innovation) were dicta. Concurring &
    Dissenting Op. at 52. Both sets of conclusions, however,
    were necessary to our upholding the transparency rule. See
    Verizon, 740 F.3d at 639–40, 644–49. Consequently, as we
    held in Verizon and reaffirm today, the Commission’s section
    706 authority extends to rules “governing broadband
    providers’ treatment of internet traffic”—including the anti-
    paid-prioritization rule—in reliance on the virtuous cycle
    theory. Verizon, 740 F.3d at 628; see 2015 Open Internet
    Order, 30 FCC Rcd. at 5625–34 ¶¶ 76–85; id. at 5623–24
    97
    ¶¶ 281–82. Even if there were any lingering uncertainty
    about the import of our decision in Verizon, we fully adopt
    here our findings and analysis in Verizon concerning the
    existence and permissible scope of the Commission’s section
    706 authority, including our conclusion that the
    Commission’s virtuous cycle theory provides reasonable
    grounds for the exercise of that authority.
    That brings us to our colleague’s suggestion that the
    Order embodies a “central paradox[]” in that the Commission
    relied on the Telecommunications Act to “increase
    regulation” even though the Act was “intended to ‘reduce
    regulation.’” Concurring & Dissenting Op. at 53. We are
    unmoved. The Act, by its terms, aimed to “encourage the
    rapid deployment of new telecommunications technologies.”
    Telecommunications Act of 1996, Pub. L. 104–104, 110 Stat
    56. If, as we reiterate here (and as the partial dissent agrees),
    section 706 grants the Commission rulemaking authority, it is
    unsurprising that the grant of rulemaking authority might
    occasion the promulgation of additional regulation. And if, as
    is true here (and was true in Verizon), the new regulation is
    geared to promoting the effective deployment of new
    telecommunications technologies such as broadband, the
    regulation is entirely consistent with the Act’s objectives.
    B.
    The Due Process Clause “requires the invalidation of
    laws [or regulations] that are impermissibly vague.” FCC v.
    Fox Television Stations, Inc., 
    132 S. Ct. 2307
    , 2317 (2012).
    US Telecom argues that the General Conduct Rule falls
    within that category. We disagree.
    The General Conduct Rule forbids broadband providers
    from engaging in conduct that “unreasonably interfere[s] with
    or unreasonably disadvantage[s] (i) end users’ ability to
    98
    select, access, and use broadband Internet access service or
    the lawful Internet content, applications, services, or devices
    of their choice, or (ii) edge providers’ ability to make lawful
    content, applications, services, or devices available to end
    users.” 2015 Open Internet Order, 30 FCC Rcd. at 5660
    ¶ 136. The Commission adopted the General Conduct Rule
    based on a determination that the three bright-line rules—
    barring blocking, throttling, and paid prioritization—were, on
    their own, insufficient “to protect the open nature of the
    Internet.” 
    Id.
     at 5659–60 ¶¶ 135–36. Because “there may
    exist other current or future practices that cause the type of
    harms [the] rules are intended to address,” the Commission
    thought it “necessary” to establish a more general, no-
    unreasonable interference/disadvantage standard. 
    Id.
     The
    standard is designed to be flexible so as to address unforeseen
    practices and prevent circumvention of the bright-line rules.
    The Commission will evaluate conduct under the General
    Conduct Rule on a case-by-case basis, taking into account a
    “non-exhaustive” list of seven factors. 
    Id.
     at 5661 ¶ 138.
    Before examining the merits of the vagueness challenge,
    we first address US Telecom’s argument that the NPRM
    provided inadequate notice that the Commission would issue
    a General Conduct Rule of this kind.            Although the
    Commission did not ultimately adopt the “commercially
    reasonable” standard proposed in the NPRM, the Commission
    specifically sought “comment on whether [it] should adopt a
    different rule to govern broadband providers’ practices to
    protect and promote Internet openness.” NPRM, 29 FCC
    Rcd. at 5604 ¶ 121. The NPRM further asked: “How can the
    Commission ensure that the rule it adopts sufficiently protects
    against harms to the open Internet, including broadband
    providers’ incentives to disadvantage edge providers or
    classes of edge providers in ways that would harm Internet
    openness? Should the Commission adopt a rule that prohibits
    99
    unreasonable discrimination and, if so, what legal authority
    and theories should we rely upon to do so?” 
    Id.
     In light of
    those questions, US Telecom was on notice that the
    Commission might adopt a different standard to effectuate its
    goal of protecting internet openness.
    US Telecom contends that the NPRM was nonetheless
    inadequate because general notice of the possible adoption of
    a new standard, without notice about the rule’s content, is
    insufficient. But the NPRM described in significant detail the
    factors that would animate a new standard. See, e.g., 
    id.
     at
    5605–06 ¶¶ 124–126; 
    id.
     at 5607 ¶¶ 129–31; 
    id.
     at 5608
    ¶ 134. The factors that are to guide application of the General
    Conduct Rule significantly resemble those identified in the
    NPRM. See 2015 Open Internet Order, 30 FCC Rcd. at
    5661–64 ¶¶ 139–45. The Rule also adopted the “case-by-
    case,” “totality of the circumstances” approach proposed in
    the NPRM. 29 FCC Rcd. at 5604 ¶ 122. By making clear
    that the Commission was considering establishment of a
    general standard and providing indication of its content, the
    NPRM offered adequate notice under the APA.
    Moving to the substance of US Telecom’s vagueness
    argument, we note initially that it comes to us as a facial
    challenge. Traditionally, a petitioner could succeed on such a
    claim “only if the enactment [wa]s impermissibly vague in all
    of its applications.” Village of Hoffman Estates v. Flipside,
    Hoffman Estates, Inc., 
    455 U.S. 489
    , 495 (1982). That high
    bar was grounded in the understanding that a “plaintiff who
    engages in some conduct that is clearly proscribed cannot
    complain of the vagueness of the law as applied to the
    conduct of others.” Holder v. Humanitarian Law Project, 
    561 U.S. 1
    , 18–19 (2010) (internal quotation marks omitted).
    More recently, however, in Johnson v. United States, 
    135 S. Ct. 2551
     (2015), the Supreme Court suggested some
    100
    skepticism about that longstanding framework. Noting that
    past “holdings squarely contradict the theory that a vague
    provision is constitutional merely because there is some
    conduct that clearly falls within the provision’s grasp,” the
    Court described the “supposed requirement of vagueness in
    all applications” as a “tautology.” 
    Id. at 2561
    . We need not
    decide the full implications of Johnson, because we conclude
    that the General Conduct Rule satisfies due process
    requirements even if we do not apply Hoffman’s elevated bar
    for facial challenges.
    Vagueness doctrine addresses two concerns: “first, that
    regulated parties should know what is required of them so
    they may act accordingly; second, precision and guidance are
    necessary so that those enforcing the law do not act in an
    arbitrary or discriminatory way.” Fox Television, 
    132 S. Ct. at 2317
    . Petitioners argue that the General Conduct Rule is
    unconstitutionally vague because it fails to provide regulated
    entities adequate notice of what is prohibited. We are
    unpersuaded. Unlike the circumstances at issue in Fox
    Television, 
    id.
     at 2317–18, the Commission here did not seek
    retroactively to enforce a new policy against conduct
    predating the policy’s adoption. The General Conduct Rule
    applies purely prospectively. We find that the Rule gives
    sufficient notice to affected entities of the prohibited conduct
    going forward.
    The degree of vagueness tolerable in a given statutory
    provision varies based on “the nature of the enactment.”
    Hoffman Estates, 
    455 U.S. at 498
    . Thus, “the Constitution is
    most demanding of a criminal statute that limits First
    Amendment rights.” DiCola v. FDA, 
    77 F.3d 504
    , 508 (D.C.
    Cir. 1996). The General Conduct Rule does not implicate that
    form of review because it regulates business conduct and
    imposes civil penalties. In such circumstances, “regulations
    101
    will be found to satisfy due process so long as they are
    sufficiently specific that a reasonably prudent person, familiar
    with the conditions the regulations are meant to address and
    the objectives the regulations are meant to achieve, would
    have fair warning of what the regulations require.” Freeman
    United Coal Mining Co. v. Federal Mine Safety & Health
    Review Commission, 
    108 F.3d 358
    , 362 (D.C. Cir. 1997).
    That standard is met here. The Commission has
    articulated “the objectives the [General Conduct Rule is]
    meant to achieve,” id.: to serve as a complement to the
    bright-line rules and advance the central goal of protecting
    consumers’ ability to access internet content of their
    choosing. See 2015 Open Internet Order, 30 FCC Rcd. at
    5659–60 ¶¶ 135–37. The Commission set forth seven factors
    that will guide the determination of what constitutes
    unreasonable interference with, or disadvantaging of, end-user
    or edge-provider access: end-user control; competitive
    effects; consumer protection; effect on innovation,
    investment, or broadband deployment; free expression;
    application agnosticism; and standard practices. See 
    id.
     at
    5661–64 ¶¶ 139–45. The Commission’s articulation of the
    Rule’s objectives and specification of the factors that will
    inform its application “mark out the rough area of prohibited
    conduct,” which suffices to satisfy due process in this context.
    DiCola, 
    77 F.3d at 509
     (internal quotation marks omitted).
    Moreover, the Commission did not merely set forth the
    factors; it also included a description of how each factor will
    be interpreted and applied. For instance, when analyzing the
    competitive effects of a practice, the Commission instructs
    that it will “review the extent of an entity’s vertical
    integration as well as its relationships with affiliated entities.”
    2015 Open Internet Order, 30 FCC Rcd. at 5662 ¶ 140. The
    Commission defines a practice as application-agnostic if it
    102
    “does not differentiate in treatment of traffic, or if it
    differentiates in treatment of traffic without reference to the
    content, application, or device.” 
    Id.
     at 5663 ¶ 144 n.344.
    Many of the paragraphs in that section of the Order also
    specifically identify the kind of conduct that would violate the
    Rule. The Commission explains, for example, that “unfair or
    deceptive billing practices, as well as practices that fail to
    protect the confidentiality of end users’ proprietary
    information, will be unlawful.” 
    Id.
     at 5662 ¶ 141. It goes on
    to emphasize that the “rule is intended to include protection
    against fraudulent practices such as ‘cramming’ and
    ‘slamming.’”      
    Id.
        And “[a]pplication-specific network
    practices,” including “those applied to traffic that has a
    particular source or destination, that is generated by a
    particular application . . . , [or] that uses a particular
    application- or transport- layer protocol,” would trigger
    concern as well. 
    Id.
     at 5663 ¶ 144 n.344.
    Given that “we can never expect mathematical certainty
    from our language,” those sorts of descriptions suffice to
    provide fair warning as to the type of conduct prohibited by
    the General Conduct Rule. Grayned v. City of Rockford, 
    408 U.S. 104
    , 110 (1972). To be sure, as a multifactor standard
    applied on a case-by-case basis, a certain degree of
    uncertainty inheres in the structure of the General Conduct
    Rule. But a regulation is not impermissibly vague because it
    is “marked by flexibility and reasonable breadth, rather than
    meticulous specificity.”     
    Id.
     (internal quotation marks
    omitted). Fair notice in these circumstances demands “no
    more than a reasonable degree of certainty.” Throckmorton v.
    National Transportation Safety Board, 
    963 F.2d 441
    , 444
    (D.C. Cir. 1992) (internal quotation marks omitted). We are
    mindful, moreover, that “by requiring regulations to be too
    specific courts would be opening up large loopholes allowing
    conduct which should be regulated to escape regulation.”
    103
    Freeman, 
    108 F.3d at 362
     (alterations and internal quotation
    marks omitted). That concern is particularly acute here,
    because of the speed with which broadband technology
    continues to evolve. The dynamic market conditions and
    rapid pace of technological development give rise to
    pronounced concerns about ready circumvention of
    particularized regulatory restrictions. The flexible approach
    adopted by the General Conduct Rule aims to address that
    concern in a field in which “specific regulations cannot begin
    to cover all of the infinite variety of conditions.” 
    Id.
    (alteration and internal quotation marks omitted).
    Any ambiguity in the General Conduct Rule is therefore a
    far cry from the kind of vagueness this court considered
    problematic in Timpinaro v. SEC, 
    2 F.3d 453
     (D.C. Cir.
    1993), on which US Telecom heavily relies. In that case, we
    found a multifactor SEC rule defining a professional trading
    account to be unconstitutionally vague because “a trader
    would be hard pressed to know when he is in danger of
    triggering an adverse reaction.” 
    Id. at 460
    . We emphasized
    that “five of the seven factors . . . are subject to seemingly
    open-ended interpretation,” and that the uncertainty is “all the
    greater when these mysteries are considered in combination,
    according to some undisclosed system of relative weights.”
    
    Id.
     Unlike in Timpinaro, in which the factors were left
    unexplained, in this case, as noted, the Commission included
    a detailed paragraph clarifying and elaborating on each of the
    factors. And because the provision at issue in Timpinaro was
    a technical definition of a professional trading account, the
    context of the regulation shed little additional light on its
    meaning. In contrast, the knowledge that the General
    Conduct Rule was expressly adopted to complement the
    bright-line rules helps delineate the contours of the proscribed
    conduct here.
    104
    Finally, the advisory-opinion procedure accompanying
    the General Conduct Rule cures it of any potential lingering
    constitutional deficiency. The Commission announced in the
    Order that it would allow companies to obtain an advisory
    opinion concerning any “proposed conduct that may implicate
    the rules,” in order to “enable companies to seek guidance on
    the propriety of certain open Internet practices before
    implementing them.” 2015 Open Internet Order, 30 FCC
    Rcd. at 5706 ¶¶ 229–30. The opinions will be issued by the
    Enforcement Bureau and “will be publicly available.” 
    Id.

    5706–07 ¶¶ 229, 231. As a result, although the Commission
    did not reach a definitive resolution during the rulemaking
    process as to the permissibility under the General Conduct
    Rule of practices such as zero-rating and usage caps, see 
    id.
     at
    5666–67 ¶ 151, companies that seek to pursue those sorts of
    practices may petition for an advisory opinion and thereby
    avoid an inadvertent infraction. The opportunity to obtain
    prospective guidance thus provides regulated entities with
    “relief from [remaining] uncertainty.” DiCola, 
    77 F.3d at 509
    ; see also Hoffman, 
    455 U.S. at 498
    .
    Petitioners argue that the advisory-opinion process is
    insufficient because opinions cannot be obtained for existing
    conduct, conduct subject to a pending inquiry, or conduct that
    is a “mere possibilit[y].” 2015 Open Internet Order, 30 FCC
    Rcd. at 5707 ¶ 232. But the fact that advisory opinions
    cannot be used for present conduct or conduct pending
    inquiry is integral to the procedure’s purpose—to encourage
    providers to “be proactive about compliance” and obtain
    guidance on proposed actions before implementing them. 
    Id.
    at 5706 ¶ 229. Petitioners also point out that the guidance
    provided in advisory opinions is not binding. See 
    id.
     at 5708
    ¶¶ 235. The Bureau’s ability to adjust its views after issuing
    an advisory opinion, however, does not negate the
    procedure’s usefulness for companies seeking to avoid
    105
    inadvertent violations of the Rule. Nonbinding opinions thus
    are characteristic of advisory processes, including the
    Department of Justice Antitrust Division’s business review
    letter procedure, which served as the model for the
    Commission’s process. See 
    id.
     Expecting the Bureau to issue
    final, irrevocable decisions on the permissibility of proposed
    conduct before seeing the actual effects of that conduct could
    produce anomalous results.
    Our colleague also identifies certain perceived
    deficiencies in the advisory-opinion process.         Notably,
    however, the partial dissent makes no argument that the
    General Conduct Rule is unconstitutionally vague. Rather, in
    arguing that the Commission’s reclassification of broadband
    is arbitrary and capricious, the partial dissent criticizes the
    advisory-opinion process on the grounds that the Bureau
    could choose to refrain from offering answers and that the
    process will be slow. See Concurring & Dissenting Op. at
    22–23. Insofar as those criticisms may seem germane to
    petitioners’ vagueness challenge, we find them unpersuasive.
    Even if the Bureau’s discretion about whether to provide an
    answer could be problematic in the absence of any further
    guidance in the Rule as to the kinds of conduct it prohibits,
    here, as explained, the Rule does provide such guidance. The
    advisory-opinion procedure simply acts as an additional
    resource available to companies in instances of particular
    uncertainty. Moreover, the partial dissent’s suppositions
    about the slowness of the process stem solely from the
    absence of firm deadlines by which the Bureau must issue an
    opinion. There is no indication at this point, however, that the
    Bureau will fail to offer timely guidance.
    In the end, the advisory-opinion procedure can be
    expected to provide valuable (even if imperfect) guidance to
    providers seeking to comply with the General Conduct Rule.
    106
    The procedure thereby alleviates any remaining concerns
    about the Rule’s allegedly unconstitutional vagueness. For
    the reasons described, we uphold the Rule.
    VII.
    We finally turn to Alamo and Berninger’s First
    Amendment challenge to the open internet rules. Having
    upheld the FCC’s reclassification of broadband service as
    common carriage, we conclude that the First Amendment
    poses no bar to the rules.
    A.
    Before moving to the merits of the challenge, we must
    address intervenor Cogent’s argument that Alamo and
    Berninger lack standing to bring this claim. Because the rules
    directly affect Alamo’s business, we conclude that Alamo has
    standing.
    In order to establish standing, a plaintiff must
    demonstrate an “injury in fact” that is “fairly traceable” to the
    defendant’s action and that can be “redressed by a favorable
    decision.” Lujan v. Defenders of Wildlife, 
    504 U.S. 555
    , 560–
    61 (1992) (alterations and internal quotation marks omitted).
    The dispute here is primarily about the first prong, injury in
    fact. An injury in fact requires “invasion of a legally
    protected interest which is (a) concrete and particularized, and
    (b) actual or imminent, not conjectural or hypothetical.” 
    Id.
    (citations and internal quotation marks omitted).
    Alamo uses fixed wireless technology to provide internet
    service to customers outside San Antonio, Texas. See Alamo
    Br., Portman Decl. ¶ 2. The company claims it “is injured by
    the Order because it is a provider of broadband Internet access
    service that the FCC seeks to regulate.” Id. ¶ 5 (italics
    omitted). As a broadband provider, Alamo is itself “an object
    107
    of the action . . . at issue.” Lujan, 
    504 U.S. at 561
    . When a
    person or company that is the direct object of an action
    petitions for review, “there is ordinarily little question that the
    action . . . has caused [it] injury, and that a judgment
    preventing . . . the action will redress it.” 
    Id.
     at 561–62.
    Here, however, Alamo seeks pre-enforcement review of the
    rules, which raises the question of whether it has
    demonstrated that the rules inflict a sufficiently concrete and
    actual injury. We conclude that Alamo has made the requisite
    showing.
    Pre-enforcement review, particularly in the First
    Amendment context, does not require plaintiffs to allege that
    they “will in fact” violate the regulation in order to
    demonstrate an injury. Susan B. Anthony List v. Driehaus,
    
    134 S. Ct. 2334
    , 2345 (2014). Standing “to challenge laws
    burdening expressive rights requires only a credible statement
    by the plaintiff of intent to commit violative acts and a
    conventional background expectation that the government
    will enforce the law.” Act Now to Stop War & End Racism
    Coalition v. District of Columbia, 
    589 F.3d 433
    , 435 (D.C.
    Cir. 2009) (internal quotation marks omitted). Because “an
    agency rule, unlike a statute, is typically reviewable without
    waiting for enforcement,” that principle applies with
    particular force here. Chamber of Commerce v. FEC, 
    69 F.3d 600
    , 604 (D.C. Cir. 1995).
    Alamo explains that the “Open Internet conduct rules
    eliminate Alamo’s discretion to manage the Internet traffic on
    its network.” Portman Decl. ¶ 5. That statement indicates
    that, were it not for the rules, Alamo would explore
    alternative methods of managing internet traffic—namely
    blocking, throttling, or paid prioritization. In the context of
    this challenge, the company’s “affidavit can only be
    understood to mean that” if the rules were removed, it would
    108
    seek to exercise its discretion and explore business practices
    prohibited by the rules. Ord v. District of Columbia, 
    587 F.3d 1136
    , 1143 (D.C. Cir. 2009). Alamo has thus adequately
    manifested its “intention to engage in a course of conduct
    arguably affected with a constitutional interest, but proscribed
    by [regulation].” Driehaus, 
    134 S. Ct. at 2342
     (internal
    quotation marks omitted). Its inability to follow through on
    that intention constitutes an injury in fact for purposes of pre-
    enforcement review of the rules.
    That conclusion is fortified by the “strong presumption of
    judicial review under the Administrative Procedure Act” and
    the understanding that “the courts’ willingness to permit pre-
    enforcement review is at its peak when claims are rooted in
    the First Amendment.”           New York Republican State
    Committee v. SEC, 
    799 F.3d 1126
    , 1135 (D.C. Cir. 2015)
    (internal quotation marks omitted). In order “to avoid the
    chilling effects that come from unnecessarily expansive
    proscriptions on speech,” “courts have shown special
    solicitude” to such claims. 
    Id.
     at 1135–36.
    Because Alamo’s standing enables us to consider the
    First Amendment arguments with respect to all three bright-
    line rules, we have no need to consider Berninger’s standing.
    See Rumsfeld v. Forum for Academic & Institutional Rights,
    Inc., 
    547 U.S. 47
    , 52 n.2 (2006).
    B.
    Alamo argues that the open internet rules violate the First
    Amendment by forcing broadband providers to transmit
    speech with which they might disagree. We are unpersuaded.
    We have concluded that the Commission’s reclassification of
    broadband service as common carriage is a permissible
    exercise of its Title II authority, and Alamo does not
    challenge that determination. Common carriers have long
    109
    been subject to nondiscrimination and equal access
    obligations akin to those imposed by the rules without raising
    any First Amendment question. Those obligations affect a
    common carrier’s neutral transmission of others’ speech, not
    a carrier’s communication of its own message.
    Because the constitutionality of each of the rules
    ultimately rests on the same analysis, we consider the rules
    together. The rules generally bar broadband providers from
    denying or downgrading end-user access to content and from
    favoring certain content by speeding access to it. In effect,
    they require broadband providers to offer a standardized
    service that transmits data on a nondiscriminatory basis. Such
    a constraint falls squarely within the bounds of traditional
    common carriage regulation.
    The “basic characteristic” of common carriage is the
    “requirement [to] hold[] oneself out to serve the public
    indiscriminately.”    Verizon, 740 F.3d at 651 (internal
    quotation marks omitted).         That requirement prevents
    common carriers from “mak[ing] individualized decisions, in
    particular cases, whether and on what terms to deal.” FCC v.
    Midwest Video Corp., 
    440 U.S. 689
    , 701 (1979) (internal
    quotation marks omitted). In the communications context,
    common carriers “make[] a public offering to provide
    communications facilities whereby all members of the public
    who choose to employ such facilities may communicate or
    transmit intelligence of their own design and choosing.” 
    Id.
    (alteration and internal quotation marks omitted). That is
    precisely what the rules obligate broadband providers to do.
    Equal access obligations of that kind have long been
    imposed on telephone companies, railroads, and postal
    services, without raising any First Amendment issue. See
    Denver Area Educational Telecommunications Consortium,
    110
    Inc. v. FCC, 
    518 U.S. 727
    , 739 (1996) (plurality opinion)
    (noting that the “speech interests” in leased channels are
    “relatively weak because [the companies] act less like editors,
    such as newspapers or television broadcasters, than like
    common carriers, such as telephone companies”); FCC v.
    League of Women Voters of California, 
    468 U.S. 364
    , 378
    (1984) (“Unlike common carriers, broadcasters are entitled
    under the First Amendment to exercise the widest journalistic
    freedom consistent with their public duties.” (alteration and
    internal quotation marks omitted)); Columbia Broadcasting
    System, Inc. v. Democratic National Committee, 
    412 U.S. 94
    ,
    106 (1973) (noting that the Senate decided in passing the
    Communications Act “to eliminate the common carrier
    obligation” for broadcasters because “it seemed unwise to put
    the broadcaster under the hampering control of being a
    common carrier and compelled to accept anything and
    everything that was offered him so long as the price was paid”
    (quoting 67 Cong. Rec. 12,502 (1926))). The Supreme Court
    has explained that the First Amendment comes “into play”
    only where “particular conduct possesses sufficient
    communicative elements,” Texas v. Johnson, 
    491 U.S. 397
    ,
    404 (1989), that is, when an “intent to convey a particularized
    message [is] present, and in the surrounding circumstances
    the likelihood [is] great that the message would be understood
    by those who viewed it,” Spence v. Washington, 
    418 U.S. 405
    , 410–11 (1974). The absence of any First Amendment
    concern in the context of common carriers rests on the
    understanding that such entities, insofar as they are subject to
    equal access mandates, merely facilitate the transmission of
    the speech of others rather than engage in speech in their own
    right.
    As the Commission found, that understanding fully
    applies to broadband providers.    In the Order, the
    Commission concluded that broadband providers “exercise
    111
    little control over the content which users access on the
    Internet” and “allow Internet end users to access all or
    substantially all content on the Internet, without alteration,
    blocking, or editorial intervention,” thus “display[ing] no such
    intent to convey a message in their provision of broadband
    Internet access services.” 2015 Open Internet Order, 30 FCC
    Rcd. at 5869 ¶ 549. In turn, the Commission found, end users
    “expect that they can obtain access to all content available on
    the Internet, without the editorial intervention of their
    broadband provider.” 
    Id.
     Because “the accessed speech is
    not edited or controlled by the broadband provider but is
    directed by the end user,” 
    id.
     at 5869–70 ¶ 549, the
    Commission concluded that broadband providers act as “mere
    conduits for the messages of others, not as agents exercising
    editorial discretion subject to First Amendment protections,”
    
    id.
     at 5870 ¶ 549. Petitioners provide us with no reason to
    question those findings.
    Because the rules impose on broadband providers the
    kind of nondiscrimination and equal access obligations that
    courts have never considered to raise a First Amendment
    concern—i.e., the rules require broadband providers to allow
    “all members of the public who choose to employ such
    facilities [to] communicate or transmit intelligence of their
    own design and choosing,” Midwest Video, 
    440 U.S. at 701
    (internal quotation marks omitted)—they are permissible. Of
    course, insofar as a broadband provider might offer its own
    content—such as a news or weather site—separate from its
    internet access service, the provider would receive the same
    protection under the First Amendment as other producers of
    internet content. But the challenged rules apply only to the
    provision of internet access as common carriage, as to which
    equal access and nondiscrimination mandates present no First
    Amendment problem.
    112
    Petitioners and their amici offer various grounds for
    distinguishing broadband service from other kinds of common
    carriage, none of which we find persuasive. For instance, the
    rules do not automatically raise First Amendment concerns on
    the ground that the material transmitted through broadband
    happens to be speech instead of physical goods. Telegraph
    and telephone networks similarly involve the transmission of
    speech. Yet the communicative intent of the individual
    speakers who use such transmission networks does not
    transform the networks themselves into speakers. See 
    id.
     at
    700–01.
    Likewise, the fact that internet speech has the capacity to
    reach a broader audience does not meaningfully differentiate
    broadband from telephone networks for purposes of the First
    Amendment claim presented here. Regardless of the scale of
    potential dissemination, both kinds of providers serve as
    neutral platforms for speech transmission. And while the
    extent of First Amendment protection can vary based on the
    content of the communications—speech on “matters of public
    concern,” such as political speech, lies at the core of the First
    Amendment, Snyder v. Phelps, 
    562 U.S. 443
    , 451 (2011)
    (internal quotation marks omitted)—both telephones and the
    internet can serve as a medium of transmission for all manner
    of speech, including speech addressing both public and
    private concerns. The constitutionality of common carriage
    regulation of a particular transmission medium thus does not
    vary based on the potential audience size.
    To be sure, in certain situations, entities that serve as
    conduits for speech produced by others receive First
    Amendment protection. In those circumstances, however, the
    entities are not engaged in indiscriminate, neutral
    transmission of any and all users’ speech, as is characteristic
    of common carriage. For instance, both newspapers and
    113
    “cable television companies use a portion of their available
    space to reprint (or retransmit) the communications of others,
    while at the same time providing some original content.” City
    of Los Angeles v. Preferred Communications, Inc., 
    476 U.S. 488
    , 494 (1986) (internal quotation marks omitted). Through
    both types of actions—creating “original programming” and
    choosing “which stations or programs to include in [their]
    repertoire”—newspapers and cable companies “seek[] to
    communicate messages on a wide variety of topics and in a
    wide variety of formats.” 
    Id.
    In selecting which speech to transmit, newspapers and
    cable companies engage in editorial discretion. Newspapers
    have a finite amount of space on their pages and cannot
    “proceed to infinite expansion of . . . column space.” Miami
    Herald Publishing Co. v. Tornillo, 
    418 U.S. 241
    , 257 (1974).
    Accordingly, they pick which articles and editorials to print,
    both with respect to original content and material produced by
    others. Those decisions “constitute the exercise of editorial
    control and judgment.” 
    Id. at 258
    . Similarly, cable operators
    necessarily make decisions about which programming to
    make available to subscribers on a system’s channel space.
    As with newspapers, the “editorial discretion” a cable
    operator exercises in choosing “which stations or programs to
    include in its repertoire” means that operators “engage in and
    transmit speech.” Turner Broadcasting System, Inc. v. FCC,
    
    512 U.S. 622
    , 636 (1994) (internal quotation marks omitted).
    The Supreme Court therefore applied intermediate First
    Amendment scrutiny to (but ultimately upheld) must-carry
    rules constraining the discretion of a cable company
    concerning which programming to carry on its channel menu.
    See 
    id.
     at 661–62.
    In contrast to newspapers and cable companies, the
    exercise of editorial discretion is entirely absent with respect
    114
    to broadband providers subject to the Order. Unlike with the
    printed page and cable technology, broadband providers face
    no such constraints limiting the range of potential content
    they can make available to subscribers. Broadband providers
    thus are not required to make, nor have they traditionally
    made, editorial decisions about which speech to transmit. See
    2015 Open Internet Order, 30 FCC Rcd. at 5753 ¶ 347, 5756
    ¶ 352, 5869–70 ¶ 549. In that regard, the role of broadband
    providers is analogous to that of telephone companies: they
    act as neutral, indiscriminate platforms for transmission of
    speech of any and all users.
    Of course, broadband providers, like telephone
    companies, can face capacity constraints from time to time.
    Not every telephone call will be able to get through
    instantaneously at every moment, just as service to websites
    might be slowed at times because of significant network
    demand. But those kinds of temporary capacity constraints do
    not resemble the structural limitations confronting newspapers
    and cable companies. The latter naturally occasion the
    exercise of editorial discretion; the former do not.
    If a broadband provider nonetheless were to choose to
    exercise editorial discretion—for instance, by picking a
    limited set of websites to carry and offering that service as a
    curated internet experience—it might then qualify as a First
    Amendment speaker. But the Order itself excludes such
    providers from the rules. The Order defines broadband
    internet access service as a “mass-market retail service”—i.e.,
    a service that is “marketed and sold on a standardized
    basis”—that “provides the capability to transmit data to and
    receive data from all or substantially all Internet endpoints.”
    2015 Open Internet Order, 30 FCC Rcd. at 5745–46 ¶ 336 &
    n.879. That definition, by its terms, includes only those
    broadband providers that hold themselves out as neutral,
    115
    indiscriminate conduits. Providers that may opt to exercise
    editorial discretion—for instance, by offering access only to a
    limited segment of websites specifically catered to certain
    content—would not offer a standardized service that can
    reach “substantially all” endpoints. The rules therefore would
    not apply to such providers, as the FCC has affirmed. See
    FCC Br. 81, 146 n.53.
    With standard broadband internet access, by contrast,
    there is no editorial limitation on users’ access to lawful
    internet content. As a result, when a subscriber uses her
    broadband service to access internet content of her own
    choosing, she does not understand the accessed content to
    reflect her broadband provider’s editorial judgment or
    viewpoint. If it were otherwise—if the accessed content were
    somehow imputed to the broadband provider—the provider
    would have First Amendment interests more centrally at
    stake. See Forum for Academic & Institutional Rights, 
    547 U.S. at
    63–65; PruneYard Shopping Center v. Robins, 
    447 U.S. 74
    , 86–88 (1980).        But nothing about affording
    indiscriminate access to internet content suggests that the
    broadband provider agrees with the content an end user
    happens to access. Because a broadband provider does not—
    and is not understood by users to—“speak” when providing
    neutral access to internet content as common carriage, the
    First Amendment poses no bar to the open internet rules.
    VIII.
    For the foregoing reasons, we deny the petitions for
    review.
    So ordered.
    WILLIAMS, Senior Circuit Judge, concurring in part and
    dissenting in part: I agree with much of the majority opinion
    but am constrained to dissent. In my view the Commission’s
    Order must be vacated for three reasons:
    I. The Commission’s justification of its switch in
    classification of broadband from a Title I information service
    to a Title II telecommunications service fails for want of
    reasoned decisionmaking. (a) Its assessment of broadband
    providers’ reliance on the now-abandoned classification
    disregards the record, in violation of its obligation under
    F.C.C. v. Fox Television Stations, Inc., 
    556 U.S. 502
    , 515
    (2009). Furthermore, the Commission relied on explanations
    contrary to the record before it and failed to consider issues
    critical to its conclusion. Motor Vehicles Mfrs. Ass’n v. State
    Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983). (b) To the
    extent that the Commission relied on changed factual
    circumstances, its assertions of change are weak at best and
    linked to the Commission’s change of policy by only the
    barest of threads. (c) To the extent that the Commission
    justified the switch on the basis of new policy perceptions, its
    explanation of the policy is watery thin and self-contradictory.
    II. The Commission has erected its regulatory scheme on
    two statutory sections that would be brought into play by
    reclassification (if reclassification were supported by reasoned
    decisionmaking), but the two statutes do not justify the rules
    the Commission has adopted.
    Application of Title II gives the Commission authority to
    apply § 201(b) of the Communications Act, 
    47 U.S.C. § 201
    (b). The Commission invokes a new interpretation of
    § 201 to sustain its ban on paid prioritization. But it has failed
    to offer a reasonable basis for that interpretation. Absent such
    a basis, the ban is not in accordance with law. 
    5 U.S.C. § 706
    (2)(A) & (C).
    2
    Application of Title II also removes an obstacle to most
    of the Commission’s reliance on § 706 of the
    Telecommunications Act of 1996, 
    47 U.S.C. § 1302
    , namely
    any rules that have the effect of treating the subject firms as
    common carriers. See Verizon Communications Inc. v.
    Federal Communications Commission, 
    740 F.3d 623
    , 650
    (2014). But the limits of § 706 itself render it inadequate to
    justify the ban on paid prioritization and kindred rules.
    I discuss § 201(b) and § 706 in subparts A and B of part
    II.
    III.    The Commission’s decision to forbear from
    enforcing a wide array of Title II’s provisions is based on
    premises inconsistent with its reclassification of broadband.
    Its explicit refusal to take a stand on whether broadband
    providers (either as a group or in particular instances) may
    have market power manifests not only its doubt as to whether
    it could sustain any such finding but also its pursuit of a “Now
    you see it, now you don’t” strategy. The Commission invokes
    something very like market power to justify its broad
    imposition of regulatory burdens, but then finesses the issue
    of market power in justifying forbearance.
    Many of these issues are closely interlocked, making it
    hard to pursue a clear expository path. Most particularly, the
    best place for examining the Commission’s explanation of the
    jewel in its crown—its ban on paid prioritization—is in
    discussion of its new interpretation of 
    47 U.S.C. § 201
    . But
    that explanation is important for understanding the
    Commission’s failure to meet its obligations under Fox
    Television, above all the obligation to explain why such a ban
    promotes the “virtuous cycle,” which (as the majority
    observes) is the primary justification for reclassification under
    Title II. Thus a discussion critical to part I of this opinion is
    3
    deferred to part II.   I ask the reader’s indulgence for any
    resulting confusion.
    * * *
    I should preface the discussion by acknowledging that the
    Commission is under a handicap in regulating internet access
    under the Communications Act of 1934 as amended by the
    Telecommunications Act of 1996. The first was designed for
    regulating the AT&T monopoly, the second for guiding the
    telecommunications industry from that monopoly into a
    competitive future. The 1996 Act begins by describing itself
    as:
    An Act [t]o promote competition and reduce regulation in
    order to secure lower prices and higher quality services
    for American telecommunications consumers and
    encourage     the    rapid    deployment      of    new
    telecommunications technologies.
    Telecommunications Act of 1996, Pub. L. No. 104-104, 
    110 Stat. 56
    . Two central paradoxes of the Commission’s position
    are (1) its use of an Act intended to “reduce regulation” to
    instead increase regulation, and (2) its coupling adoption of a
    dramatically new policy whose rationality seems heavily
    dependent on the existing state of competition in the
    broadband industry, under an Act intended to “promote
    competition,” with a resolute refusal even to address the state
    of competition. In the Commission’s words, “Thus, these
    rules do not address, and are not designed to deal with, the
    acquisition or maintenance of market power or its abuse, real
    or potential.” Order ¶ 11 n.12.
    4
    I
    I agree with the majority that the Commission’s
    reclassification of broadband internet as a telecommunications
    service may not run afoul of any statutory dictate in the
    Telecommunications Act. But in changing its interpretation,
    the Commission failed to meet the modest requirements of
    Fox Television.
    Fox states that an agency switching policy must as
    always “show that there are good reasons for the new policy.”
    
    556 U.S. at 515
    . But in special circumstances more is
    required. An “agency need not always provide a more
    detailed justification than what would suffice for a new policy
    created on a blank slate. [But s]ometimes it must—when, for
    example, its new policy rests upon factual findings that
    contradict those which underlay its prior policy; or when its
    prior policy has engendered serious reliance interests that
    must be taken into account.” 
    Id.
    Here the Commission justifies its decision on two bases:
    changed facts and a new policy judgment. To the extent it
    rests on new facts, Fox requires us to examine whether there
    is really anything new. Fox also, of course, requires us to
    consider reliance interests, regardless of what the Commission
    has said about them. Thus novel facts and reliance interests
    are plainly at issue. The Commission also argues that its
    policy change would be reasonable even if the facts had not
    changed. Order ¶ 360 n.993 (“[W]e clarify that, even
    assuming, arguendo, that the facts regarding how [broadband]
    is offered had not changed, in now applying the Act’s
    definitions to these facts, we find that the provision of
    [broadband] is best understood as a telecommunications
    service, as discussed [elsewhere] . . . and disavow our prior
    interpretations to the extent they held otherwise.”). In sum
    then, at a minimum, we must inquire whether the Commission
    5
    gave reasonable attention to petitioners’ claims of reliance
    interests, how much the asserted factual change amounts to,
    and finally whether the Commission has met the minimal
    burden of showing “that there are good reasons for the new
    policy.” I address them in that order.
    (a) Reliance. The Order deals with reliance interests
    summarily, noting, “As a factual matter, the regulatory status
    of broadband internet access service appears to have, at most,
    an indirect effect (along with many other factors) on
    investment.” Order ¶ 360. The Commission’s support for the
    conclusion is weak and its pronouncement superficial.
    To the extent that the Commission’s judgment relies on
    the presence of “many other factors,” it relies on an
    irrelevance. The proposition that “many other factors” affect
    investment is a truism. In a complex economy there will be
    few phenomena that are entirely driven by a single variable.
    Investment in broadband obviously reflects such matters as
    market saturation, the cost of capital, obsolescence,
    technological innovation, and a host of macroeconomic
    variables. Put more generally, the presence of causal factors
    X and Y doesn’t show the irrelevance of factor Z. The
    significance of these factors tells us little about how much the
    relatively permissive regime that has hitherto applied accounts
    for the current robust broadband infrastructure. At least in
    general terms, the Commission elsewhere seems to answer
    that the old regime accounts for much. In an introductory
    paragraph it commends “the ‘light-touch’ regulatory
    framework that has facilitated the tremendous investment and
    innovation on the Internet.” Order ¶ 5.
    For its factual support, the Commission essentially lists
    several anecdotes about what happened to stock prices and
    what corporate executives said about investment in response
    to Commission proposals for regulatory change. For example,
    6
    the Order notes that, after the Commission proposed tougher
    rules, the stocks of telecommunications companies
    outperformed the broader market. Order ¶ 360. This might
    be interesting if the Commission had performed a
    sophisticated analysis trying to hold other factors constant. In
    the absence of such an analysis, the evidence shows only that
    the threat of regulation was not so onerous as to precipitate
    radical stock market losses. The Order also has a quotation
    from the Time Warner Cable COO saying, in response to an
    FCC announcement of possible Title II classification
    (accompanied by some vague Commission assurances), “So
    . . . yes, we will continue to invest.” Id. n.986 (emphasis
    added by the Commission). Citation of this remark would be
    an apt response to a strawman argument that there would have
    been no investment in broadband if the new rules had always
    applied, but not to the argument that a significant portion of
    the current investment was made in reliance on the old
    regime. Further, it is reasonable to expect that corporate
    executives—with their incentives to enhance the firm’s
    appearance as an attractive investment opportunity and thus to
    keep its cost of capital down—would take the most favorable
    view of a new policy consistent with their obligations to
    investors not to paint too rosy a picture.
    A more important (and logically prior) question is why
    this evidence matters at all. I take Fox’s position on reliance
    interests to be addressed to both fairness and efficiency. If a
    regulatory switch will significantly undercut the productivity
    and value of past investments, made in reasonable reliance on
    the old regime, rudimentary fairness suggests that the agency
    should take that into account in evaluating a possible switch.
    And a pattern of capricious change would undermine any
    agency purpose of encouraging future investment on the basis
    of new rules. But the effect of past policy on past investment
    is quite different from future levels of investment. For
    example, the Environmental Protection Agency’s new
    7
    regulations on coal-fired power plants very well might spur
    investment in energy by making legacy coal-fired plants less
    feasible to operate, thus encouraging investment in renewable
    energy to replace them. But that tells us little about whether
    the prior regulations on coal-fired plants and their alternatives,
    adjusted in light of reasonably foreseeable change, had a
    material impact on prior energy investments.
    The Commission also argues that “the regulatory history
    regarding the classification of broadband Internet access
    service would not provide a reasonable basis for assuming that
    the service would receive sustained treatment as an
    information service in any event.” Order ¶ 360. In short, the
    Commission says that reliance was not reasonable. The
    statement misreads the history of the classification of
    broadband. In March 2002, the Commission classified cable
    broadband as an information service, see In the Matter of
    Inquiry Concerning High-Speed Access to the Internet over
    Cable and Other Facilities (the “Cable Modem Declaratory
    Ruling”), 17 F.C.C. Rcd. 4798 (2002); soon after that Order
    was affirmed by the Supreme Court in National Cable &
    Telecommunications Ass’n v. Brand X Internet Service, 
    545 U.S. 967
     (2005), the Commission reclassified the transmission
    component of DSL service as an information service as well.
    See Appropriate Framework for Broadband Access to the
    Internet Over Wireline Facilities et al. (the “Wireline
    Broadband Classification Order”), 20 F.C.C. Rcd. 14853
    (2005). The Commission continued to hold that view until
    2010, when in the 2010 Notice, Notice of Inquiry, Framework
    for Broadband Internet Service, 25 F.C.C. Rcd. 7866 (2010),
    it sought comment on reclassification (though rejecting it in
    the ultimate 2010 Order). I’m puzzled at the Commission’s
    implicit claim, Order ¶ 360, that judicial uncertainly—dating
    back to the 9th Circuit’s 2000 decision in AT&T Corp. v. City
    of Portland, 
    216 F.3d 871
     (9th Cir. 2000), reading the statute
    to compel classification as a telecommunications service—
    8
    made it unreasonable for firms investing in provision of
    internet access to think that the Commission would persist in
    its longheld commitment. The Commission offered fierce
    resistance to the 9th Circuit decision, resistance that
    culminated in its success in Brand X. It seems odd, in this
    context, to discount firms’ reliance on the Commission’s own
    assiduously declared views.
    According to data that Commission itself uses, Order ¶ 2,
    broadband providers invested $343 billion1 during the five
    years after Brand X, from 2006 through 2010. This amounts
    to about $3,000 on average for every American household.
    U.S.            Census              Bureau,             Quickfacts,
    https://www.census.gov/quickfacts/table/PST045215/00.2 For
    the Commission to ignore these sums as investment in
    reliance on its rules is to say it will give reliance interests zero
    weight.
    No one supposes that firms’ past investment in reliance
    on a set of rules should give them immunity to regulatory
    change. But Fox requires an agency at least to make a serious
    assessment of such reliance. The Commission has failed to do
    so.

    This uses the average number of households between 2010
    and 2014 (116 million), which gives an average of $2,951 per
    household. Between 2006 and 2010, there were fewer households,
    so the average is likely above $3,000 per household.
    9
    (b) Changed facts. The Commission identifies two
    changes, neither of which seems very radical or logically
    linked to the new regime. First, it argues that consumers now
    use broadband “to access third party content, applications and
    services.” Order ¶¶ 330, 346-47. But that is nothing new. In
    the Order from well over a decade ago that Brand X affirmed,
    the Commission said that consumers “may obtain many
    functions from companies with whom the cable operator has
    not even a contractual relationship” instead of from their cable
    internet service provider. Declaratory Ruling and Notice of
    Proposed Rulemaking, 17 F.C.C. Rcd. 4798 ¶¶ 25, 38 & n.153
    (2002) (“Declaratory Ruling”).
    Second, the Order points to the emphasis that providers
    put on the “speed and reliability of transmission separately
    from and over” other features. Order ¶¶ 330, 351. Again,
    there is nothing new about these statements from broadband
    providers, who have been advertising speed for decades. See
    Dissenting Statement of Commissioner Ajit Pai to Order (“Pai
    Dissent”) at 357-58; Dissenting Statement of Commissioner
    Michael O’Rielly to Order at 391. As Justice Scalia put it in
    an undisputed segment of his Brand X dissent, broadband
    providers (like pizzerias) “advertise[] quick delivery” as an
    “advantage[] over competitors.” 
    545 U.S. at
    1007 n.1 (Scalia,
    J., dissenting).
    At no point does the Commission seriously try to quantify
    these alleged changes in the role or speed of internet service
    providers. Even if there were changes in degree in these
    aspects of the internet, the Commission doesn’t explain why
    an increase in consumer access to third-party content, or an
    increase in competition to offer high-speed service, would
    make application of Title II more appropriate as a policy
    matter now than it was at the time of the Declaratory Ruling
    at issue in Brand X.
    10
    I confess I do not understand the majority’s view that the
    section of Fox on changed circumstances, quoted above, is not
    triggered so long as the agency’s current view of the
    circumstances is sustainable. Maj. Op. 47. Whatever the
    soundness of such a view, it seems inapplicable where, as
    here, the agency explicitly invokes changed circumstances:
    “Changed factual circumstances cause us to revise our earlier
    classification of broadband Internet access service.” Order
    ¶ 330.
    (c) New reasoning. Perhaps recognizing the frailty of its
    claims of changed facts, the Commission tries to cover its
    bases by switching to the alternative approach set forth in Fox,
    a straightforward disavowal of its prior interpretation of the
    1996 Act and related policy views. See, e.g., Order ¶ 360
    n.993.
    The Commission justifies its reclassification almost
    entirely in terms of arguments that provision of such services
    as DNS and caching, when provided by a broadband provider,
    do not turn the overall service into an “information service.”
    Rather, those functions in its view fit within § 153(24)’s
    exception for telecommunications systems management.
    Order ¶ 365-81. Thus, the Commission set for itself a highly
    technical task of classification, concluding that broadband
    internet access could fit within the literal terms of the
    pertinent statutory sections. And it accomplished the task.
    That it could do so is hardly surprising in view of the broad
    leeway provided by Brand X, which gave it authority to
    reverse the policy judgment it had made in the decision there
    under review, the Declaratory Ruling.
    But in doing so the Commission performed Hamlet
    without the Prince—a finding of market power or at least a
    consideration of competitive conditions. The Declaratory
    Ruling sustained in Brand X invoked serious economic
    11
    propositions as the basis for its conclusion. For example, the
    Brand X majority noted that in reaching its initial
    classification decision the Commission had concluded that
    “broadband services should exist in a minimal regulatory
    environment that promotes investment and innovation in a
    competitive market.” Id. ¶ 5, quoted by Brand X, 
    545 U.S. at 1001
     (internal quotation marks omitted). But the Commission
    has now discovered, for reasons still obscure, that a “minimal
    regulatory environment,” far from promoting investment and
    innovation, retards them, so that the Commission must replace
    that environment with a regime that is far from “minimal.”
    And when parties claimed that the Declaratory Ruling
    was inconsistent with the Commission’s decision to subject
    facilities-based enhanced services providers to an obligation
    to offer their wires on a common-carrier basis to competing
    enhanced-services providers, In re Amendment of Sections
    64.702 of the Commission’s Rules and Regulations (Third
    Computer Inquiry), 104 F.C.C. 2d 958, 964 ¶ 4 (1986), the
    Brand X Court responded by looking to the policy reasons that
    the Commission itself had invoked, reasons grounded in
    concern over monopoly. The Court said:
    In the Computer II rules, the Commission subjected
    facilities-based providers to common-carrier duties not
    because of the nature of the “offering” made by those
    carriers, but rather because of the concern that local
    telephone companies would abuse the monopoly power
    they possessed by virtue of the “bottleneck” local
    telephone facilities they owned. . . . The differential
    treatment of facilities-based carriers was therefore a
    function not of the definitions of “enhanced service” and
    “basic service,” but instead of a choice by the
    Commission to regulate more stringently, in its
    discretion, certain entities that provided enhanced service.
    12
    
    545 U.S. at 996
    .         Thus the Court recognized the
    Commission’s practice of regarding risks of “abuse [of]
    monopoly power” as pivotal in Computer II. While the 1996
    Act by no means conditions classification under Title II on a
    finding of market power, Brand X shows that the Court
    recognized the relevance of market power to the
    Commission’s classification decisions. See Declaratory
    Ruling ¶ 47 (resting the classification decision in part on the
    desire to avoid “undermin[ing] the goal of the 1996 Act to
    open all telecommunications markets to competition”).
    Of course the Court’s citation of these instances of
    Commission reliance on the economic and social values
    associated with competition are just examples brought to our
    attention by Brand X. In addressing activities on the
    periphery of highly monopolized telephone service, the
    Commission has for nearly four decades made the presence or
    prospect of competition the touchstone for refusal to apply
    Title II. The Computer II decision, for example, says of the
    Computer I decision, “A major issue was whether
    communications common carriers should be permitted to
    market data processing services, and if so, what safeguards
    should be imposed to insure that the carriers would not engage
    in anti-competitive or discriminatory practices.” In re
    Amendment of Section 64.702 of the Commission’s Rules and
    Regulations (Second Computer Inquiry), 77 F.C.C. 2d 384,
    389-90 ¶ 15 (1980) (“Computer II”). In the Computer II
    decision, it is hard to go more than a page or so without
    encountering discussion of competition.          The decision
    concludes that, “In view of all of the foregoing evidence of an
    effective competitive situation, we see no need to assert
    regulatory authority over data processing services.” Id. at
    433, ¶ 127. The competitiveness of the market was in large
    part what the inquiry was about.             See Jonathan E.
    Nuechterlein & Philip J. Weiser, Digital Crossroads 190-91
    13
    (2d ed. 2013) (explaining link of Computer II’s unbundling
    rules to FCC’s concern over monopoly).
    Yet in the present Order the Commission contradicted its
    prior strategy and explicitly declined to offer any market
    power analysis: “[T]hese rules do not address, and are not
    designed to deal with, the acquisition or maintenance of
    market power or its abuse, real or potential.” Order ¶ 11 n.12.
    In fact, as we’ll see, many of the Commission’s policy
    arguments assert what sound like claims of market power, but
    without going through any of the fact-gathering or analysis
    needed to sustain such claims.
    The Order made no finding on market power; in order to
    do so it would have to answer a number of basic questions.
    Most notably, as shown in Figure 1 below, there are a fairly
    large number of competitors in most markets, with 74% of
    American households having access to at least two fixed
    providers giving speeds greater than 10 Mbps and 88% with at
    least two fixed providers giving access to service at 3 Mbps.
    In re Inquiry Concerning the Deployment of Advanced
    Telecommunications Capability to All Americans in a
    Reasonable & Timely Fashion, & Possible Steps to Accelerate
    Such Deployment Pursuant to Section 706 of the
    Telecommunications Act of 1996, as Amended by the
    Broadband Data Improvement Act, 30 F.C.C. Rcd. 1375 ¶ 83
    (2015) (“2015 Broadband Report”). Furthermore, 93% of
    Americans have access to three or more mobile broadband
    providers—access which at least at the margin must operate in
    competition with suppliers of fixed broadband. In re
    Implementation of Section 6002(b) of the Omnibus Budget
    Reconciliation Act of 1993: Annual Report and Analysis of
    Competitive Market Conditions with Respect to Mobile
    Wireless, Seventeenth Report, 29 F.C.C. Rcd. 15311 ¶ 51,
    Chart III.A.2 (2014).
    14
    Figure 1: American Households’ Access to
    Fixed Broadband Providers
    Source: 2015 Broadband Report, Chart 2.
    The Commission emphasizes how few people have
    access to 25 Mbps, but that criterion is not grounded in any
    economic analysis. For example, Netflix—a service that
    demands high speeds—recommends only 5 Mbps for its high-
    definition quality service and 3 Mbps for its standard
    definition quality.    Netflix, Internet Connection Speed
    Recommendations, https://help.netflix.com/en/node/306. A
    likely explanation for why there has not been more rollout of
    higher speeds is that many people are reluctant to pay the
    extra price for it. Indeed, the 2015 Broadband Report
    indicates that fewer than 30% of customers for whom 25
    Mbps broadband is available actually order it.          2015
    Broadband Report ¶ 41 (including Table 3 and Chart 1).
    15
    That many markets feature few providers offering service
    at 25 Mbps or above is hardly surprising. In a competitive
    world of rapidly improving technology, it’s unreasonable to
    expect that all firms will simultaneously launch the
    breakthrough services everywhere, especially in a context in
    which more than 70% of the potential customers decline to
    use the latest, priciest service.
    The Commission established the 25 Mbps standard in its
    2015 Broadband Report ¶ 45.              Its explanations seem
    superficial at best. For example, it relies on the marketing
    materials of broadband providers touting the availability and
    benefits of speeds at or greater than 25 Mbps. Id. ¶ 28.
    Perhaps the authors of the Order have never had the
    experience of a salesperson trying to sell something more
    expensive than the buyer inquired about—and, not
    coincidentally, more lucrative for the salesperson. The
    Commission also justifies the standard by arguing that 10
    Mbps would be insufficient to “participate in an online class,
    download files, and stream a movie at the same time” and to
    “[v]iew 2 [high-definition] videos.” Id. ¶ 39. This is like
    setting a standard for cars that requires space for seven
    passengers. The data seem to suggest that many American
    families are unwilling to pay the extra to be sure that all
    members can have continuous, simultaneous, separate access
    to high-speed connectivity (perhaps some of them read?
    engage in conversation?). The fact that the Commission
    strains so much to justify its arbitrary criterion shows how out
    of line with reality such a criterion is. The weakness of the
    Commission’s reasoning suggests that its main purpose in
    setting the “standard” may simply be to make it appear that
    millions of Americans are at the mercy of only one supplier,
    or at best two, for critically needed access to the modern
    world. All without bothering to conduct an economic
    analysis!
    16
    Of course, if the Commission had assessed market power,
    it would have needed to define the relevant market, to
    understand the extent to which providers of different speeds
    and different services compete with each other. When
    defining markets for purposes of assessing competition, the
    Department of Justice and Federal Trade Commission use the
    “small but significant and non-transitory increase in price”
    (“SSNIP”) test. The test tries to determine whether a market
    actor can benefit from a hypothetical increase in price,
    indicating market power. U.S. Department of Justice and the
    Federal Trade Commission, Horizontal Merger Guidelines 9
    (2010) (“Horizontal Merger Guidelines”).            But the
    Commission did not conduct such a test, and we cannot say
    how it would come out.
    Because broadband competition is geographically
    specific, simple market share data at a national level are of
    limited value. But firms that provide service to large numbers
    of consumers, albeit not everywhere, seem likely to rank as
    potential competitors quite broadly. With these limits in
    mind, we can look at U.S. subscriber numbers for each of the
    firms in the market, Leichtman Research, About 645,000 Add
    Broadband       in    the    Third     Quarter      of   2015,
    http://www.leichtmanresearch.com/press/111715release.html,
    and construct a Herfindahl–Hirschman Index, which in fact is
    1,445 points. This level is in the Department of Justice’s
    Range for “Unconcentrated Markets”—that is, markets where
    no firm has market power. Horizontal Merger Guidelines at
    18-19. I report below the data used to construct the index. In
    fact, this number is biased upward (and thus biased toward
    finding market power), since the data for several smaller
    companies are grouped as if for only one, making it seem as if
    there is more concentration than there in fact is.
    Similarly, the Commission scoffs at what it regards as
    low turnover in customers’ use of mobile service providers,
    17
    but the rate of turnover actually looks quite substantial. The
    Commission points to average monthly churn rates of 1.56%
    in mobile broadband across four leading providers. Order
    ¶ 98 n.211. Assuming that a single person does not switch
    more than once in a year, that rate of churn means that
    18.72% of customers switch providers each year, suggesting
    quite robust competition. Interestingly, the Commission is
    especially hard on declines in churn rate, id., which in the
    absence of increased concentration or some new obstacle to
    switching might well suggest increased consumer satisfaction.
    To bolster its switching data claims, the Commission
    points to documents in which parties to the rulemaking make
    conclusory assertions purportedly showing that 27 percent of
    mobile broadband consumers do not switch though
    “dissatisfied” with their current carriers. Order ¶ 98. Without
    a plausible measure of “dissatisfaction” (none is offered), the
    number is meaningless.

    Even though never making any finding on market power,
    the Commission seems almost always to speak of fixed and
    mobile broadband separately. Of course to a degree the
    statute requires this. But if the Commission were the least bit
    serious about the market dysfunction that might provide
    support for its actions, it would consider competition between
    the two. The frequent articles in the conventional press about
    fixed broadband customers’ “cutting the cord” in favor of
    complete reliance on mobile suggests it would be an
    interesting inquiry.
    None of the above is intended to suggest that the
    Commission could not have made a sustainable finding that
    every firm in every relevant market has market power. My
    aim is simply to make two points: (1) that such a degree of
    market power cannot be assumed, as the Commission itself
    seems to acknowledge in its disclaimer of interest in market
    power, Order ¶ 11 n.12; and (2) that the Commission’s
    reliance on consumers’ “high switching costs,” id. ¶ 81
    (discussed below in part II), which is an implicit assertion that
    the providers have market power, poses an empirical question
    that is susceptible of resolution and is in tension with the
    Commission’s assertion that it is not addressing “market
    power or its abuse, real or potential.”
    In a move evidently aimed at circumventing the whole
    market power issue (despite Title II’s origin as a program for
    monopoly regulation), the Commission rests on its “virtuous
    cycle” theory, to wit the fact that “innovations at the edges of
    the network enhance consumer demand, leading to expanded
    investments in broadband infrastructure that, in turn, spark
    new innovations at the edge.” Order ¶ 7. The Commission
    clearly expects the policy adopted here to cause increases in
    broadband investment.
    20
    I see no problem with the general idea. Indeed, it seems
    to me it captures an important truth about any sector of the
    economy. Though the subsectors may compete over rents, the
    prosperity of each subsector depends on the prosperity of the
    others—at least it does so unless some wholly disruptive
    technology replaces one of the subsectors. American wheat
    producers, American railroads, steamship lines, and wheat
    consumers around the globe participate in a virtuous cycle;
    medical device inventors, hospitals, doctors, and patients
    participate in a virtuous cycle. Innovation, to be sure, is
    especially robust in the information technology and
    application sectors, but a mutual relationship between
    subsectors pervades the economy.
    There is an economic classification issue that the
    Commission does not really tackle: whether broadband
    internet access is like transportation or is a platform in a two-
    sided market, i.e., a business aiming to “facilitate interactions
    between members of . . . two distinct customer groups,” David
    S. Evans & Richard Schmalensee, The Industrial
    Organization of Markets with Two-Sided Platforms, 3
    COMPETITION POLICY INTERNATIONAL 151, 152 (2007), which
    in this case would be edge providers and users. (Two-sided
    markets are barely discussed at all, with the only mentions of
    any sort in the Order at ¶¶ 151 n.363, 338 & n.890, 339
    n.897.) Although the Commission seems at one point to
    characterize broadband internet access as a two-sided market,
    see id. ¶ 338, it nowhere develops any particular
    consequences from that classification or taps into the vast
    scholarly treatment of the subject. The answer to the question
    may well shed light on the reasonableness of the regulations,
    but in view of the Commission’s non-reliance on the
    distinction we need not go there.
    I do not understand the Commission to claim that its new
    rules will have a direct positive effect on investment in
    21
    broadband. The positive effect is expected from the way in
    which, in the Commission’s eyes, the new rules encourage
    demand for and supply of content, which it believes will
    indirectly spur demand for and investment in broadband
    access.
    The direct effect, of which the Commission doesn’t really
    speak, seems unequivocally negative, as petitioner United
    States Telecom Association (“USTA”) argues. USTA Pet’rs’
    Br. 4 (“Individually and collectively, these rules will
    undermine future investment by large and small broadband
    providers, to the detriment of consumers.”); see also id. 54.
    Besides imposing the usual costs of regulatory compliance,
    the Order increases uncertainty in policy, which both reason
    and the most recent rigorous econometric evidence suggest
    reduce investment. Scott R. Baker, Nicholas Bloom & Steven
    J. Davis, Measuring Economic Policy Uncertainty, 131
    QUARTERLY JOURNAL OF ECONOMICS (forthcoming 2016).
    (Though the paper is focused on economy-wide policy
    uncertainty and effects, it is hard to see why the linkage
    shown would not apply in an industry-specific setting.) In
    fact, the Order itself acknowledges that vague rules threaten to
    “stymie” innovation, Order ¶ 138, but then proceeds to adopt
    vague rules.
    Here, a major source of uncertainty is the Internet
    Conduct Standard, which forbids broadband providers to
    “unreasonably interfere with or unreasonably disadvantage”
    consumer access to internet content. 
    47 C.F.R. § 8.11
    . All of
    these       terms—“unreasonably,”         “interfere,”     and
    “disadvantage”—are vague ones that increase uncertainty for
    regulated parties. Indeed, the FCC itself is uncertain what the
    policy means, as indicated by the FCC Chairman’s admission
    that even he “do[esn’t] really know” what conduct is
    proscribed. February 26, 2015 Press Conference, available at
    http://goo.gl/oiPX2M (165:30-166:54).        The Commission
    22
    does announce a “nonexhaustive list” of seven factors to be
    used in assessing providers’ practices, including “end-user
    control,” “consumer protection,” “effect on innovation,” and
    “free expression.” Order ¶¶ 138-45. But these factors
    themselves are vague and unhelpful at resolving the
    uncertainty.
    The Commission made an effort to palliate the negative
    effect of its “standards” by establishing a procedure for
    obtaining advisory opinions. Order ¶¶ 229-39. It delegated
    authority to issue such opinions to its Enforcement Bureau,
    perhaps thereby telegraphing its general mindset on how
    broadly it intends its prohibitions to be read. But the Bureau
    has complete discretion on whether to provide an answer at
    all. Order ¶ 231. Further, any advice given will not provide a
    basis for longterm commitments of resources: the Bureau is
    free to change its mind at will, and as the opinions will be
    issued only at the staff level, the Commission reserves its
    freedom to act contrary to the staff’s conclusions at any time.
    Order ¶ 235. I do not understand this to mean that the
    Commission will seek penalties against parties acting in
    reliance on an opinion while it is still in effect, but parties in
    receipt of a favorable opinion are on notice that they may be
    forced to shut down a program the minute the Bureau reverses
    itself or the Commission countermands the Bureau.
    Besides affording rather fragile assurance, the advisory
    process promises to be slow. “[S]taff will have the discretion
    to ask parties requesting opinions, as well as other parties that
    may have information relevant to the request or that may be
    impacted by the proposed conduct, for additional
    information.” Id. ¶ 233. Given these possible information
    requests from various parties, including adverse ones, it is
    unsurprising that the Commission is unwilling to give any
    timeliness commitment, explicitly “declin[ing] to establish
    23
    any firm deadlines to rule on [requests for advisory opinions]
    or issue response letters.” Id. ¶ 234.
    The palliative effect of these procedures may be
    considerable for the very large service providers. They are
    surely accustomed to having their lawyers suit up, research all
    the angles, participate in proceedings after notice has been
    given to all potentially adversely affected parties, and receive,
    after an indefinite stretch, a green light or a red one. For the
    smaller fry, the internet service provider firms whose growth
    is likely to depend on innovative business models (precisely
    the sort that seem likely to run afoul of the Commission’s
    broad prescriptions; see part II.B), the slow and costly
    advisory procedure will provide only a mild antidote to those
    prescriptions’ negative effect. This of course fits the general
    pattern of regulation’s being more burdensome for small firms
    than for large, as larger firms can spread regulation’s fixed
    costs over more units of output. See Nicole V. Crain & W.
    Mark Crain, The Impact of Regulatory Costs on Small Firms 7
    (2010). And in evaluating the impact on investment in
    broadband, which the Commission assures us the Order will
    stimulate, quality is surely relevant as well as quantity.
    Further, given the breadth and vagueness of the standards,
    many of the acts for which firms are driven to seek advice will
    likely be rather picayune. As head of the Civil Aeronautics
    Board in its what proved to be its waning days, Alfred Kahn
    got a call in the middle of the night from an airline trying to
    find out whether its application to transport sheep from
    Virginia to England had been approved. “The matter was
    urgent, because the sheep were in heat!” Susan E. Dudley,
    Alfred Kahn, 1917-2010, Remembering the Father of Airline
    Deregulation, 34 REGULATION 8, 10 (2011). The internet we
    know wasn’t built by firms requesting bureaucratic approval
    for every move.
    24
    Furthermore, 
    47 U.S.C. § 207
    , which applies to
    broadband providers once they are subject to Title II,
    increases uncertainty yet more. Section 207 allows “[a]ny
    person claiming to be damaged by any common carrier . . .
    [to] either make complaint to the Commission . . . , or . . .
    bring suit for the recovery of the damages for which such
    common carrier may be liable under the provisions of this
    chapter.” In other words, reclassification exposes broadband
    providers to the direct claims of supposedly injured parties,
    further increasing uncertainty and risk. In short, the Order’s
    probable direct effect on investment in broadband seems
    unambiguously negative.
    As to the hoped-for indirect effect, the idea that it will be
    positive depends on the supposition that these new rules (the
    specific and the general) will cure some material problem,
    will avert some threat that either is now burdening the internet
    or could reasonably be expected to do so absent the
    Commission’s intervention. Why, precisely, the observer
    wants to know, has the Commission repudiated the policy
    judgment it made in 2002, that “broadband services should
    exist in a minimal regulatory environment that promotes
    investment and innovation in a competitive market”?
    Declaratory Ruling ¶ 5. The answer evidently turns on the
    Commission’s conclusion that broadband providers have
    indulged (or will indulge) in behavior that threatens the
    internet’s “virtuous cycle.” Indeed, the majority points to the
    need to reclassify broadband so that the Commission could
    promulgate the rules as the Commission’s “‘good reason’ for
    [its] change in position,” Maj. Op. 43, and indeed its only
    reason. But the record contains multiple reasons for thinking
    that the Commission’s new rules will retard rather than
    enhance the “virtuous cycle,” and the Commission’s failure to
    answer those objections renders its decision arbitrary and
    capricious. I now turn to those arguments, first in the context
    25
    of 
    47 U.S.C. §§ 201
    , 202 (part II.A) and then in the context of
    § 706 of the 1996 Act (part II.B).
    II
    Having reclassified broadband service under Title II, the
    Commission has relied on two specific provisions to sustain
    its actions: § 201(b) of the Communications Act, 
    47 U.S.C. § 201
    (b), and § 706 of the Telecommunications Act of 1996,
    
    47 U.S.C. § 1302
    . The petitioners contend that neither
    provides adequate support for the Commission’s actions.
    Furthermore, as just mentioned, the Commission’s arguments
    here bear directly on the reasonableness of the reclassification
    decision itself.
    A
    Petitioners Alamo Broadband Inc. and Daniel Berninger
    (“Alamo-Berninger”) argue that even if Title II could properly
    be applied to broadband service, that Title gives the
    Commission no authority to prohibit reasonable rate
    distinctions. Alamo-Berninger Br. 17-19. Berninger is a
    would-be edge provider working on new technology that he
    believes could provide much enhanced telephone service—but
    only if he could be assured that “latency, jitter, and packet loss
    in the transmission of a communication will [not] threaten
    voice quality and destroy the value proposition of a high-
    definition service.” Declaration of Daniel Berninger, October
    13, 2015, at 2. He is ready to pay for the assurance of high-
    quality service, and asserts that the Commission’s ban on paid
    prioritization    will   obstruct      successful     commercial
    development of his innovation. Berninger appears to be
    exactly the sort of small, innovative edge provider that the
    Commission claims its Order is designed to assist. In the
    26
    words of Shel Silverstein’s children’s song, “Some kind of
    help is the kind of help we all can do without.”
    For our purposes, of course, the question is whether, as
    the Alamo-Berninger brief argues, the section of the statute
    invoked by the Commission under Title II, namely § 201(b),
    authorizes the ban, or, more precisely, whether the
    Commission has offered any reasonable interpretation of
    § 201(b) that would encompass the ban.
    A number of points by way of background: First, nothing
    in the Order suggests that the paid prioritization ban allows
    any exception for rate distinctions based on differing costs of
    transmission, time-sensitivity of the material transmitted, or
    congestion levels at the time of transmission, all variables
    historically understood to justify distinctions in rates. Alfred
    E. Kahn, The Economics of Regulation (1988), at 63 (different
    costs), 63-64 (different elasticities of demand, as would be
    reflected in time sensitivity), 88-94 (congestion). The Alamo-
    Berninger brief cites the FCC chairman’s observation in
    Congress, “There is nothing in Title II that prohibits paid
    prioritization,” Hearing before the Subcommittee on
    Communications and Technology of the United States House
    of Representatives Committee on Energy and Commerce, and
    Technology of the United States House Commission,” Video
    at      44:56     (May       20,     2014),      available    at
    http://go.usa.gov/3aUmY, but that need not detain us. More
    important, general principles of public utility rate regulation
    have always allowed reasonable rate distinctions, with many
    factors determining reasonableness. Kahn, The Economics of
    Regulation, at 63 (noting that, “from the very beginning,
    regulated companies have been permitted to discriminate in
    the economic sense, charging different rates for various
    services”). But the ban adopted by the Commission prohibits
    rate differentials for priority handling regardless of factors
    that would render them reasonable under the above
    27
    understandings.      Although the Order provides for the
    possibility of waiver, it cautions, “An applicant seeking
    waiver relief under this rule faces a high bar. We anticipate
    granting such relief only in exceptional cases.” Order ¶ 132.
    Second, in a case discussing the terms “unjust” and
    “unreasonable” as used in § 201(b) and in its fraternal twin
    § 202(a), we said that those words “open[] a rather large area
    for the free play of agency discretion.” Orloff v. FCC, 
    352 F.3d 415
    , 420 (D.C. Cir. 2003); see also Global Crossing
    Telecomms., Inc. v. Metrophones Telecomms., Inc., 
    550 U.S. 45
     (2007) (recognizing the Commission’s broad authority to
    define “unreasonable practice[s]” under § 201(b)).         But
    “large” is not infinite.
    Third, in the order under review in Orloff the
    Commission focused on § 202 but mentioned § 201. We
    summarized it as holding that “if a practice is just and
    reasonable under § 202, it must also be just and reasonable
    under § 201.” Orloff, 
    352 F.3d at
    418 (citing Orloff v.
    Vodafone AirTouch Licenses LLC d/b/a Verizon Wireless, 17
    F.C.C. Rcd. 8987, 8999 (2002) (“Defendants . . . offer[] the
    same defenses to the section 201(b) claim as they do to the
    section 202(a) claim. We reject Orloff’s section 201(b) claim.
    As noted, section 201(b) declares unlawful only ‘unjust or
    unreasonable’ common-carrier practices. For the reasons
    discussed [regarding section 202(a)], we find Defendants’
    concessions practices to be reasonable.”)).
    Fourth, the Commission (at least for the moment) allows
    ISPs to provide consumers differing levels of service at
    differing prices. As it says in its brief, “The Order does not
    regulate rates—for example, broadband providers can (and
    some do) reasonably charge consumers more for faster service
    or more data.” Commission Br. 133. The statement is true
    (for now) vis-à-vis rates to consumers. But the ban on paid
    28
    prioritization obviously regulates rates—the rates paid by
    edge providers; it insists that the incremental rate for assured
    or enhanced quality of service must be zero. Although I
    cannot claim that the parties’ exposition of the technology is
    clear to me, it seems evident that the factors affecting quality
    of delivery to a consumer include not only whatever service
    characteristics go into promised (and delivered) speed at the
    consumer end but also circumstances along the route. “Paid
    peering” (discussed below) would be unintelligible if it were
    otherwise.
    With these background points in mind, I turn to the
    Commission’s treatments of “unjust” and “unreasonable”
    under §§ 201 and 202. Its principal discussions of the concept
    have occurred in the context of § 202(a), which bars “any
    unjust or unreasonable discrimination in charges,
    practices. . . ,” etc. Section § 201(b), relied on by the
    Commission here, is very similar but does not include the
    word “discrimination.” § 201(b) (“All charges, practices,
    classifications, and regulations for and in connection with
    such communication service, shall be just and reasonable, and
    any such charge, practice, classification, or regulation that is
    unjust or unreasonable is declared to be unlawful . . . .”) The
    Order’s language explaining its view of § 201(b) doesn’t
    mention this difference, so evidently the Commission’s
    interpretation doesn’t rely on it.
    The Commission’s decisions under § 202 have plainly
    recognized the permissibility of reasonable rate differences.
    In In re Dev. of Operational, Tech. & Spectrum Requirements
    for Meeting Fed., State & Local Pub. Safety Agency Commc'n
    Requirements Through the Year 2010, 15 F.C.C. Rcd. 16720
    (2000), for example, the Commission issued an order
    declaring that premium charges for prioritized emergency
    mobile services were not unjust and unreasonable. In full
    accord with the usual understanding of rate regulation, the
    29
    Commission said, “Section 202 . . . does not prevent carriers
    from treating users differently; it bars only unjust or
    unreasonable discrimination.      Carriers may differentiate
    among users so long as there is a valid reason for doing so.”
    Id. at 16730-31(emphasis in original)). It reasoned that, “in
    emergency situations, non-[emergency] customers simply are
    not ‘similarly situated’ with [emergency] personnel” because
    “the ability of [the latter] to communicate without delays
    during emergencies is essential.” Id. at 16731. Even when
    the Commission engages in full-scale rate regulation (which it
    purports to eschew in the Order), it explicitly recognizes that
    reasonable price differentials are appropriate where the
    services in question are unlike. See, e.g., In re AT&T
    Communications Revisions to Tariff F.C.C. No. 12, 6 F.C.C.
    Rcd. 7039 ¶ 8 (1991).
    Tellingly, in its prioritized emergency mobile services
    decision the Commission did not see fit to discuss § 201 at all.
    The principle underlying the Commission’s understanding of
    § 202 was a broad one—that allowance of differential rates
    based on “valid reasons” advances the public interest.
    Whatever explains the lack of any reference to § 201, the
    Commission’s recognition that differential rates were not
    inherently unjust or unreasonable under § 202 requires, as a
    minimum of coherent reasoning, that it offer some explanation
    why the same words in § 201 should preclude such
    differentials. See Orloff v. Vodafone AirTouch Licenses LLC
    d/b/a Verizon Wireless, 17 F.C.C. Rcd. 8987, 8999 (finding
    reasonableness and justness under § 202 to be sufficient for
    finding the same under § 201). Of course this is no more than
    a recognition of the principle, prevailing throughout the era of
    federal regulation of natural monopolies, that it is just and
    reasonable that customers receiving extra speed or reliability
    should pay extra for it. A classic and pervasive example is the
    differential in natural gas transmission between firm and
    interruptible service. See, e.g., Fort Pierce Utilities Auth. of
    30
    City of Fort Pierce v. FERC, 
    730 F.2d 778
    , 785-86 (D.C. Cir.
    1984).
    I note that the ban here is simply on differences in rates,
    an issue normally addressed under statutory language barring
    discrimination.      So it is at least anomalous that the
    Commission here relies on § 201(b), which says nothing about
    discrimination, rather than § 202(a), which does. The only
    reason I can discern is that the Commission’s interpretation of
    § 202 was more clearly established, and obviously didn’t ban
    reasonable discriminations. Accordingly, the Commission
    jumped over to § 201(b), about which it had said relatively
    little.
    In the passage where the Order claims support from
    § 201(b), the Commission appears to acknowledge that it has
    never interpreted that section to support a sweeping ban on
    quality-of-service premiums, but, speaking of its anti-
    discrimination decisions (evidently under both §§ 201(b) and
    202(a)), it says that “none of those precedents involved
    practices that the Commission has twice found threaten to
    create barriers to broadband development that should be
    removed under section 706.” Order ¶ 292. This is an odd
    form of statutory interpretation. Finessing any effort to fit the
    agency action within the statutory language, it only claims
    that the banned practice threatens broadband deployment.
    Maybe the theory works, but it can do so only by a sturdy
    showing of how the banned conduct posed a “threat.” As
    we’ll see, the Commission has made no such showing, let
    alone a sturdy one.
    Indeed, I can find no indication—and the Commission
    presents none—that any of the agencies regulating natural
    monopolies, such as the Interstate Commerce Commission,
    Federal Energy Regulatory Commission, or Federal
    Communications Commission—has ever attempted to use its
    31
    mandate to assure that rates are “just and reasonable”3 to
    invalidate a rate distinction that was not unreasonably
    discriminatory. To uproot over a century of interpretation—
    and with so little explanation—is truly extraordinary.
    In its interpretation of § 201 the Commission rests its
    claim of a “threat” to the “virtuous cycle” theory mentioned
    above: “innovations at the edges of the network enhance
    consumer demand, leading to expanded investments in
    broadband infrastructure that, in turn, spark new innovations
    at the edge,” Order ¶ 7, and the cycle repeats on and on.
    The key question is what underlies the Commission’s
    idea that a ban on paid prioritization will lead to more content,
    giving the cycle extra spin (or, equivalently, reducing the drag
    caused by paid prioritization). Order ¶ 7. In what way will an
    across-the-board ban on paid prioritization increase edge
    provider content (and thus consumer demand)? Or, putting it
    in terms of a “threat,” how does paid prioritization threaten
    the flourishing of the edge provider community (and thus
    consumer demand, and thus broadband deployment)?
    3
    See, e.g., Interstate Commerce Act of 1887, 
    24 Stat. 379
    , § 1
    (“All charges made for any service rendered or to be rendered in the
    transportation of passengers or property as aforesaid, or in
    connection therewith, or for the receiving, delivering, storage, or
    handling of such property, shall be reasonable and just; and every
    unjust and unreasonable charge for such service is prohibited and
    declared to be unlawful.”); Federal Power Act, 16 U.S.C. § 824d
    (“All rates and charges made, demanded, or received by any public
    utility for or in connection with the transmission or sale of electric
    energy subject to the jurisdiction of the Commission, and all rules
    and regulations affecting or pertaining to such rates or charges shall
    be just and reasonable, and any such rate or charge that is not just
    and reasonable is hereby declared to be unlawful.”)
    32
    In fact, as we’ll see, the Commission’s hypothesis that
    paid prioritization has deleterious effects seems not to rest on
    any evidence or analysis. Further, the Order fails to address
    critiques and alternatives.
    I look first to the support offered by the Commission for
    its claim. The Order asserts that “[t]he Commission’s
    conclusion [that allowance of paid prioritization would
    disadvantage certain types of edge providers] is supported by
    a well-established body of economic literature, including
    Commission staff working papers.” Order ¶ 126. This claim
    is, to put it simply, false. The Commission points to four
    economics articles, none of which supports the conclusion that
    all distinctions in rates, even when based on differentials in
    service, will reduce the aggregate welfare afforded by a set of
    economic transactions.4 Indeed, the Commission plainly
    didn’t look at the articles. None of them even addresses price
    distinctions calibrated to variations in quality of service;
    rather they are devoted to the sort of price differences
    addressed by the Robinson-Patman Act, 
    15 U.S.C. § 13
    ,
    targeting sellers who sell the same good of the same quality at
    different prices. Three say that in some circumstances rules
    against price differentials can be beneficial (to repeat, the
    articles speak of rules against differentials not related to

    quality of service), not that they are beneficial.5 The fourth
    paper, still within the sphere of non-quality-related price
    distinctions, is still worse for the Commission, concluding that
    “a flat ban” on price discrimination (even assuming no
    differential in cost and quality, unlike the Commission rule)
    “could have adverse welfare consequences,” and that “the
    analysis does not reveal whether there is any implementable
    form of regulation that would be welfare-improving.” Katz,
    The Welfare Effects, at 165.
    It is probably no coincidence that the author of three of
    these articles, Michael Katz, a former chief economist at the
    Commission, filed a declaration in this proceeding opposing
    the type of regulation adopted in the Order as overly broad,
    especially given that the behavior banned was at most
    responsible for only hypothetical harms. Protecting and

    alternatives he offers shortly.
    The Order also points to two old Commission reports that
    it claims support its argument. Order ¶ 126 n.297. They do
    not. One, Jay M. Atkinson & Christopher C. Barnekov, A
    Competitively Neutral Approach to Network Interconnection,
    OPP Working Paper Series, No. 34, at 15 (2000), deals with
    network interconnection pricing and advocates a “bill and

    Katz, Price Discrimination, at 1454 (“uniform pricing is
    more efficient than price discrimination when the number of
    uninformed consumers is small”); Katz, Output and Welfare, at 37
    (“there may be scope for improving market performance through
    regulation” of price discrimination); Yoshida, Third Degree Price
    Discrimination, at 244 (“[i]n general, we cannot expect” the
    condition required for regulation to improve welfare to be true).
    34
    keep” system (“under which carriers split equally those costs
    that are solely incremental to interconnection, and recover all
    remaining costs from their own customers,” according to the
    report, 
    id.
     at ii). Unlike the articles cited, it does address
    variations in quality of service, but only to argue that the
    ability of one provider to lower its quality doesn’t undermine
    the case for “bill and keep” because the quality-lowering
    provider will bear “the main impact itself.” Id. at 20. This is
    an interesting proposition, but, assuming its truth, it doesn’t
    connect in any obvious way to a flat ban on paid
    prioritization; if the Commission knows a way to make that
    connection, it hasn’t revealed it.
    The second, Gerald W. Brock, Telephone Pricing to
    Promote Universal Service and Economic Freedom, OPP
    Working Paper Series, No. 18 (1986), is an interesting
    consideration of the possible welfare losses that may follow
    from pricing that collects a high proportion of fixed costs
    from usage fees. As with the Atkinson & Barnekov paper, its
    connection to paid prioritization is unclear, and the
    Commission’s opinion writers have made no effort even to
    identify a connection, much less explain it. In discussing a
    possible anti-discrimination rule, the paper posits one under
    which a firm may adopt “any combination of two-part tariffs,
    volume discounts, and so forth but is required to offer the
    same set of prices to all customers.” Id. at 44. Although it
    isn’t clear that the paper gives an endorsement to such a rule,
    such an endorsement would not support the Commission’s
    ban on quality-of-service based differentials.
    I apologize for taking the reader through this parade of
    irrelevancies. But it is on these that the Commission has
    staked its claim to analytical support for the idea that paid
    prioritization poses a serious risk to broadband deployment.
    35
    The Commission does point to episodes supposedly
    supporting its view that paid prioritization constitutes a
    significant threat. Order ¶ 69, 79 n.123. It is, however,
    merely pointing to a handful of episodes among the large
    number of transactions conducted by many broadband
    providers. Furthermore, neither in this Order nor in the 2010
    Broadband Order, 25 F.C.C. Rcd. at 17915-26, ¶¶ 20-37, cited
    by this Order as support, Order ¶ 79 n.123, does the
    Commission sift through the evidence to show that any
    episode impaired the ability of the internet to maximize
    consumer satisfaction and the flourishing of edge providers in
    the aggregate, as opposed to harm to a particular edge
    provider. Nor does it show whether, if there was harm, a far
    narrower rule would not have handled the problem. (For
    example, if a broadband provider throttled an edge provider’s
    content at the same time as the broadband provider provided
    similar content, then—assuming no justification—grounds for
    action against such behavior could be discerned. Compare
    § 616(a)(3) of the Communications Act, 
    47 U.S.C. § 536
    (a)(3).) In his dissent to the Order, Commissioner Pai,
    using terms perhaps feistier than would suit a court,
    summarized it as follows:
    The evidence of these continuing threats? There is
    none; it’s all anecdote, hypothesis, and hysteria. A small
    ISP in North Carolina allegedly blocked VoIP calls a
    decade ago. Comcast capped BitTorrent traffic to ease
    upload congestion eight years ago. Apple introduced
    FaceTime over Wi-Fi first, cellular networks later.
    Examples this picayune and stale aren’t enough to tell a
    coherent story about net neutrality. The bogeyman never
    had it so easy.
    Pai Dissent at 333. And Judge Silberman’s observations
    about the episodes marshalled to support the precursor order
    vacated in Verizon seem as applicable today as then:
    36
    That the Commission was able to locate only four
    potential examples of such conduct is, frankly,
    astonishing. In such a large industry where, as Verizon
    notes, billions of connections are formed between users
    and edge providers each year, one would think there
    should be ample examples of just about any type of
    conduct.
    Verizon, 740 F.3d at 664-65 (Judge Silberman, dissenting
    from the decision’s dicta).
    The short of it is that the Commission has nowhere
    explained why price distinctions based on quality of service
    would tend to impede the flourishing of the internet, or,
    conversely, why the status quo ante would not provide a
    maximum opportunity for the flourishing of edge providers as
    a group—or small innovative edge providers as a subgroup.
    It gets worse. Having set forth the notion that paid
    prioritization poses a threat to broadband deployment—so
    much so as to justify jettisoning its historic interpretation of
    §§ 201(b), 202(a), and resting that notion on conclusory
    assertions of parties and irrelevant scholarly material—the
    Commission then fails to respond to criticisms and
    alternatives proposed in the record, in clear violation of the
    demands of State Farm, 
    463 U.S. at 43, 51
    .
    I start with comments in the record explaining the
    problems that the ban on paid prioritization could cause in the
    broadband market. The comments suggest that by effectively
    banning pricing structures that could benefit some people
    substantially, but impose minimal (and seemingly quite
    justifiable) costs on others, the ban on paid prioritization
    could replace the virtuous cycle with a vicious cycle, in which
    regulatory overreach reduces the number and quality of
    services available, reducing demand for broadband, and in
    37
    turn reducing the content and services available owing to the
    reduced number of users. Investment would suffer as the
    number of users declines (or fails to grow as it otherwise
    would have).
    For example, the joint comment by the International
    Center for Law & Economics and TechFreedom paints a
    picture in which innovation and investment could be
    substantially harmed by the ban on paid prioritization:
    With most current [internet service] pricing models,
    consumers have little incentive or ability (beyond the
    binary choice between consuming or not consuming)
    to prioritize their use of data based on their
    preferences. In other words, the marginal cost to
    consumers of consuming high-value, low-bit data (like
    VoIP [transmitting voice over the internet], for
    example) is the same as the cost of consuming low-
    value, high-bit data (like backup services, for
    example), assuming neither use exceeds the user’s
    allotted throughput. And in both cases, with all-you-
    can-eat pricing, consumers face a marginal cost of $0
    (at least until they reach a cap). The result is that
    consumers will tend to over-consume lower-value data
    and under-consume higher-value data, and,
    correspondingly, content developers will over-invest
    in the former and under-invest in the latter. The
    ultimate result—the predictable consequence of
    mandated neutrality rules—is a net reduction in the
    overall value of content both available and consumed,
    and network under-investment.
    Comments of International Center for Law & Economics and
    TechFreedom at 17 (July 17, 2014).
    38
    In other words, paid prioritization would encourage ISP
    innovations such as providing special speed for voice
    transmission (for which timeliness and freedom from latency
    and jitter—delays or variations in delay in delivery of
    packets—are very important), at little or no cost to services
    where timeliness (especially timeliness measured in
    milliseconds) is relatively unimportant. Similarly, pricing for
    extra speed would incentivize edge providers to innovate in
    technologies that enable their material to travel faster (or
    reduce latency or jitter) even in the absence of improved ISP
    technology. To be sure, usage caps (which are permissible for
    now under the Order) provide some incentive for edge
    providers to invest in innovations enabling faster transit
    without extra Mbps and thus enable their customers to enjoy
    more service at less risk of exceeding the caps. But the usage
    caps are a blunt instrument, as their burden is felt by all
    consumers, whereas the sort of pricing increment forbidden by
    the Commission would be focused (de facto) on the edge
    providers for whom speed and other quality-of-service
    features are especially important. Thus paid prioritization
    would yield finely tuned incentives for innovation exactly
    where it is needed to relieve network congestion. These
    innovations could improve the experience for users, driving
    demand and therefore investment. The Order nowhere
    responds to this contention.
    At oral argument it was suggested that with paid
    prioritization the speed of the high rollers comes at the
    expense of others. This is true and not true. Consider ways
    that the United States government applies paid prioritization
    in two monopolies that it runs, Amtrak and the U.S. Postal
    Service. Both offer especially fast service at a premium. If
    the resources devoted to providing extra speed for the
    premium passengers and mail were spread evenly among all
    passengers and mail, the now slower moving passengers and
    mail could travel a bit faster. But the revenues available
    39
    would be diminished for want of the premium charges, and in
    any event it is hard to see how coach passengers or senders of
    ordinary mail are injured by the availability of speedier,
    costlier service.
    Of course one can imagine priority pricing that could
    harm consumers.        The record contains a declaration
    recognizing the possibility and opposing the Commission’s
    solution. It is by the author of three of the very economics
    papers that the Commission says support its position, Michael
    Katz, who was a chief economist of the Commission under
    President Clinton.      Pointing to the risk of distorting
    competition and harming customers through banning pricing
    strategies and “full use of network management techniques,”
    Katz urged disallowing conduct “only in response to specific
    instances of identified harm, rather than imposing sweeping
    prohibitions that throw out the good with the bad.” Katz
    Declaration at 2-3.
    Perhaps the Commission has answers to this. But despite
    going out of its way to rely on papers by Katz that were
    irrelevant, the Commission never deigned to reflect on the
    concerns he expressed about harm to innovation and
    consumer welfare.
    Furthermore, in its single-minded focus on innovation at
    the “edge” (and only some kinds of innovation at that), the
    Commission ignored arguments that the process of providing
    broadband service is itself one where innovation, not only in
    technology but in pricing strategies and business models, can
    contribute to maximization of the internet’s value to all users.
    A comment of Professor Justin Hurwitz makes the point:
    Current research suggests that traditional, best-effort,
    non-prioritized routing may yield substantially
    inefficient use of the network resource. It may well
    40
    turn out to be the case that efficient routing of data like
    streaming video requires router-based prioritization. It
    may even turn out that efficient routing of streaming
    video data is necessarily harmful to other data—it may
    not be possible to implement a single network
    architecture that efficiently handles data with
    differentiated characteristics. If this is the case, then it
    may certainly be “commercially reasonable” that
    streaming video providers pay a premium for the
    efficient handling of their data, in order to compensate
    for the negative externalities that those uses impose
    upon other users and uses.
    Comments of Justin (Gus) Hurwitz at 17 (July 18, 2014).
    (Professor Hurwitz may have been mistakenly operating on
    the belief that the Commission would allow for
    “commercially reasonable” practices.          The Commission
    ultimately rejected a ban on “commercially unreasonable”
    practices, Order ¶ 150, but created no defense of commercial
    reasonableness for any of its bans. The Commission did
    create an exception for “reasonable network management” for
    rules other than the ban on paid prioritization. Order ¶ 217.)
    Generalizing the point made by Professor Hurwitz:
    Unless there is capacity for all packets to go at the same speed
    and for that speed to be optimal for the packets for which
    speed is most important, there must be either (1) prioritization
    or (2) identical speed for all traffic. If all go at the same
    speed, then service is below optimal for the packets for which
    speed is important. If there is unpaid prioritization, and it is
    made available to the senders of packets for which
    prioritization is important, then (1) those senders get a free
    ride on costs charged in part to other packet senders and (2)
    those senders have less incentive to improve their packets’
    technological capacity to use less transmission capacity.
    41
    Allowance of paid prioritization eliminates those two defects
    of unpaid prioritization.
    One prominent critic of the ban on paid prioritization—
    Timothy Brennan, the Commission’s chief economist at the
    time the Order was initially in production, who has called the
    rules “an economics-free zone”6—offered an alternative that
    addressed these concerns. His argument goes as follows. If
    some potential content providers might refrain from entry for
    fear that poor service might stifle advantageous interactions
    with other sites (thus thwarting the virtuous cycle), that fear
    could be assuaged by requiring that ISPs meet minimum
    quality standards. Brennan writes that
    a minimum quality standard does not preclude above-
    minimum quality services and pricing schemes that
    could improve incentives to improve broadband
    networks and facilitate innovation in the development
    and marketing of audio and video content. Moreover,
    a minimum quality standard should reduce the costs of
    and impediments to congestion management necessary
    under net neutrality.
    Comments of International Center for Law & Economics and
    TechFreedom at 48; see also 
    id. at 47
    . This is a proposal
    based on the notion that consumers value the things prevented
    by the Order, but it offers an alternative that solves a (perhaps
    hypothetical) problem at which the Order is aimed (relieving
    content providers of the fear discussed above and thus
    ensuring the virtuous cycle), without such significant costs as
    6
    See http://www.wsj.com/articles/economics-free-obamanet-
    1454282427.
    42
    those the commentators discussed.       The Order offers no
    response.
    Notice that the drag on innovation to which these
    commentators allude has a clear adverse effect on the virtuous
    cycle invoked by the Commission. To be sure, as a general
    matter investment at the edge provider and the ISP level will
    be mutually reinforcing, but sound incentives for innovation at
    both levels will provide more benefit enhancements to
    consumers per dollar invested.
    I’ve already noted with bemusement the Commission’s
    utter disregard of arguments by two of its former chief
    economists, Michael Katz and Tim Brennan, that were
    submitted into the record. Lest the point be understated, I
    should also mention that the views of yet a third, Thomas W.
    Hazlett, also appear in several submissions. CenturyLink
    points to Thomas W. Hazlett and Dennis L. Weisman, Market
    Power in U.S. Broadband Industries, 38 REVIEW OF
    INDUSTRIAL ORGANIZATION 151 (2011), for the proposition
    that there is no evidence that broadband providers are earning
    supra-normal rates of return. This may be another clue why
    the Commission steers clear of any claim of market power.
    And the Comments of Daniel Lyons (July 29, 2014), Net
    Neutrality     and      Nondiscrimination      Norms      in
    Telecommunications, 1029 ARIZ. L. REV. 1029 (“Lyons
    Comments”) at 1070, cite Thomas W. Hazlett & Joshua D.
    Wright, The Law and Economics of Network Neutrality, 45
    IND. L. REV. 767, 798 (2012), for the argument that there is
    much to be learned from antitrust law, which treats vertical
    arrangements on a rule-of-reason basis. To the argument that
    antitrust enforcement is costly, time-consuming and
    unpredictable, Hazlett and Wright acknowledge the point but
    argue that it has been responsible for some of the genuine
    triumphs in the telecommunications industry, such as the
    43
    break-up of AT&T. The Lyons submission finds confirmation
    in the Department of Justice’s Ex Parte Submission in the
    2010 proceeding, arguing that “antitrust is up to the task of
    protecting consumers from vertical contracts that threaten
    competition.”7
    The silent treatment given to three of its former chief
    economists seems an apt sign of the Commission’s thinking as
    it pursued its forced march through economic rationality.
    The Commission does invoke justifications other than the
    “virtuous cycle” to support its Order. For example, it asserts
    that “[t]he record . . . overwhelmingly supports the
    proposition that the Internet’s openness is critical to its ability
    to serve as a platform for speech and civic engagement,” for
    which it cites comments from three organizations. Order ¶ 77
    & n.118. The Order makes no attempt, however, to explain
    how these particular rules, and the language of § 201, relate to
    these goals. A raw assertion that the internet’s openness
    promotes free speech, while in a general sense surely true (at
    least on some assumptions about the meaning of “openness”),
    is not enough reasoning to support a ban on paid
    prioritization.
    Further, having eschewed any claim that it found the ISPs
    to possess market power, Order ¶ 11 n.12 (“[T]hese rules do
    not address, and are not designed to deal with, the acquisition
    or maintenance of market power or its abuse, real or
    7
    Lyons Comments at 1070 (quoting Thomas W. Hazlett &
    Joshua D. Wright, The Law and Economics of Network Neutrality,

    in Broadband Competition: A National Broadband Plan for Our
    Future, Ex Parte Submission of the United States Department of
    Justice, 
    2010 WL 45550
     (2010).
    44
    potential”), the Commission invokes a kind of “market-
    power-lite.” The argument fundamentally is that ISPs occupy
    a “gatekeeper” role and may use that role to block content
    whose flow might injure them: They might want to do this in
    order to prioritize their content over that of other content
    providers (or perhaps other purposes inconsistent with
    efficient use of the net). And they might be able to do this
    because impediments to customers’ switching will enable
    them to restrict others’ content without incurring a penalty in
    the form of customer cancellations. Order ¶¶ 79-82.
    The Commission’s reliance on market-power-lite is
    puzzling in a number of ways. First, the Commission’s
    primary fact—the existence of switching costs—begs the
    question of why the Commission did not look at other forms
    of evidence for market power. See Horizontal Merger
    Guidelines, 11 (saying that “the costs and delays of switching
    products” are taken into account in implementing the
    hypothetical monopolist test). If the Commission relies on
    one possible source of market power, one wonders why it
    would not seek data that would pull together the full range of
    sources, including market concentration. It may be that the
    Department of Justice’s submission in the Notice of Inquiry
    that ultimately led to the Order, see In re A National
    Broadband Plan for Our Future, 24 F.C.C. Rcd. 4342 (2009),
    reviewing some of the data but reaching no conclusion, led the
    Commission to believe that a serious inquiry would come up
    empty. In re Economic Issues in Broadband Competition: A
    National Broadband Plan for Our Future, Ex Parte
    Submission of the United States Department of Justice, 
    2010 WL 45550
     (2010).
    Second, even a valid finding of market power would not
    be much of a step towards validating a ban on paid
    prioritization or linking it to § 201. Eight years before the
    Order, the Federal Trade Commission ordered a staff study
    45
    and published the results.            Broadband Connectivity
    Competition Policy, Federal Trade Commission (2007),

    dband-connectivity-competition-policy/v070000report.pdf.
    As with DOJ later, the report was non-committal on the issue
    of market power but reviewed (1) ISP incentives to
    discriminate and not to discriminate under conditions of
    market power, id. at 72-75, and (2) varieties of paid
    prioritization, assessing their risks and benefits, id. at 83-97.
    Instead of a nuanced assessment building on the FTC staff
    paper (or for that matter contradicting it), the Commission
    adopted a flat prohibition, paying no attention to
    circumstances under which specific varieties of paid
    prioritization would (again, assuming market power)
    adversely or favorably affect the value of the internet to all
    users. In the absence of such an evaluation, the Order’s
    scathing terms about paid prioritization, used as a justification
    for the otherwise unexplained switch in interpretation of
    § 201(b), fall flat. Order ¶ 292.
    Finally, the Commission’s argument that paid
    prioritization would be used largely by “well-heeled
    incumbents,” Order ¶ 126 n.286, not only is ungrounded
    factually (so far as appears) but contradicts the Commission’s
    decision (and the reasoning behind its decision) not to apply
    its paid prioritization ban to types of paid prioritization that
    use caching technology.8
    8
    Since I would conclude that the Commission acted
    arbitrarily and capriciously in its reclassification decision
    regardless of whether DNS and caching fit the
    telecommunications management exception, 
    47 U.S.C. § 153
    (24), I will not address that.
    46
    Caching is the storage of frequently accessed data in a
    location closer to some users of the data. The provider of the
    caching service (in some contexts called a content delivery
    network) thus increases the speed at which the end user can
    access the data. Order ¶ 372 & n.1052. In effect, then, it
    prioritizes the content in question. It is provided sometimes
    by ISPs (sometimes at the expense of edge providers) and
    sometimes by third parties. 
    Id.
    For example, Netflix has entered agreements with several
    large broadband providers to obtain direct access to their
    content delivery networks, i.e., cached storage on their
    networks. See Order ¶¶ 198-205, 200 n.504 (noting that
    Netflix has entered into direct arrangements with Comcast,
    Verizon, Time Warner Cable, and AT&T); see also
    http://www.bloomberg.com/bw/articles/2014-02-24/netflixs-
    deal-with-comcast-isnt-about-net-neutrality-except-that-it-is.
    Contracts under which caching is supplied by broadband
    providers or by third parties are often called paid peering
    arrangements. Regardless of the name, they involve expenses
    incurred directly or indirectly by an edge provider, using a
    caching technology to store content closer to end users, so as
    to assure accelerated transmission of its content via a
    broadband provider.
    Although the Commission acknowledges that caching
    agreements raise many of the same issues as other types of
    paid prioritization, it expressly declines to adopt regulations
    governing them, opting instead to hear disputes related to such
    arrangements under §§ 201 & 202 and to “continue to
    monitor” the situation. Order ¶ 205. The Order defines paid
    prioritization as “the management of a broadband provider’s
    47
    network to directly or indirectly favor some traffic over other
    traffic, including through use of techniques such as traffic
    shaping, prioritization, resource reservation, or other forms of
    preferential traffic management, either (a) in exchange for
    consideration (monetary or otherwise) from a third party, or
    (b) to benefit an affiliated entity.” Order ¶ 18. If caching is a
    form of preferential traffic management—and I cannot see
    why it is not—then paid access to broadband providers’
    caching facilities violates the paid prioritization ban, or at any
    rate would do so but for the Commission’s decision in ¶ 205
    that it will evaluate such arrangements on a case-by-case basis
    rather than condemn them root-and-branch.
    Curiously, although the Commission seems to be
    absolutely confident in its policy view on paid prioritization, it
    recognizes that it actually lacks experience with the subject.
    One objector argued that the Commission could not apply
    § 201(b) to paid prioritization because “no broadband
    providers have entered into such arrangements or even have
    plans to do so.” Order ¶ 291 n.748 (quoting NCTA
    Comments at 29). Instead of contradicting the premise, the
    Commission responded by noting that at oral argument in
    Verizon a provider had said that but for the Commission’s
    2010 rules it would be pursuing such arrangements. Id. So all
    the claims about the harm threatened by paid prioritization are
    at best projections. We saw earlier the irrelevance of the
    studies on which the Commission relied to make those
    projections. As to caching, with which it has plenty of
    familiarity, the Commission uses the temperate wait-and-see
    approach. See Order ¶ 203.
    The Commission never seriously tries to reconcile its
    hesitancy here with its claims that harms arising from paid
    prioritization are so extreme as to call for an abandonment of
    its longtime precedents interpreting §§ 202(a) and 201(b).
    See Order ¶ 292.
    48
    The Commission does note that the disputes over caching
    “are primarily between sophisticated entities.” Order ¶ 205.
    But as it never says how that affects matters, we remain in the
    dark on the distinction. Indeed, the size and sophistication of
    the entities involved might exacerbate concerns that ISPs are
    likely to create a fast lane for large edge providers.
    The Commission also notes that deep packet inspection—
    along with other similar types of network traffic management
    that rely on packet characteristics—is the technical means
    underlying the paid prioritization that it condemns. With that
    technology, it says, an ISP can examine the content of packets
    of data as they go by and prioritize some over others. See
    Order ¶ 85. If the Commission believes that this technical
    factor plays a role in justifying different treatment, it fails to
    explain why. Insofar as it suggests that packet inspection
    might be abused, id., it never explains why rules against such
    abuse would not fit its historic understanding of unreasonable
    or unjust discrimination (and that of the historic price
    regulatory systems).
    The oddity of the Commission’s view is nicely captured
    in its treatment of a pro-competition argument submitted by
    ADTRAN opposing the ban on paid prioritization. ADTRAN
    argued that the ban (1) would hobble competition by disabling
    some edge providers from securing the prioritization that
    others obtain via Content Delivery Networks (“CDNs”) (the
    premise is that some edge providers, perhaps because of
    relatively low volume, do not have access to CDNs; the
    Commission does not contest the premise), ADTRAN
    Comment at 7, J.A. 275, and (2) would “cement the
    advantages enjoyed by the largest edge providers that
    presently obtain the functional equivalent of priority access by
    constructing their own extensive networks that interconnect
    directly with the ISPs.” Order ¶ 128 (quoting ADTRAN
    Reply Comments at 18 (September 15, 2014)).                 The
    49
    Commission never answers the first objection (except insofar
    as it is entangled with the second). As to the second it says
    only that it does “not seek to disrupt the legitimate benefits
    that may accrue to edge providers that have invested in
    enhancing the delivery of their services to end users.” Order
    ¶ 128. That answer seems to confirm ADTRAN’s complaint:
    the Commission’s split policy will “cement the advantages”
    secured by those who invested in interconnecting networks.
    Oddly, the Commission supports the ban on paid prioritization
    as tending to prevent “the bifurcat[ion] of the Internet into a
    ‘fast’ lane for those willing and able to pay and a ‘slow’ lane
    for everybody else,” and as protecting “‘user-generated video
    and independent filmmakers’ that lack the resources of major
    film studios to pay priority rates.” Order ¶ 126; see also id.
    n.286 (quoting a commenter’s concern over advantages going
    to “well-heeled incumbents”). In short, then, the Commission
    is against slow lanes and fast lanes, and against advantages for
    the established or well-heeled—except when it isn’t.
    The Commission’s favored treatment of paid peering
    (wait-and-see) over paid prioritization (banned) brings to
    mind the Commission’s practice of sheltering the historic
    AT&T monopoly from competition. See Nuechterlein &
    Weiser, 11-12, 40. Contrary to the conventional notion that
    only regulatees enjoy the benefits of unreasoned agency favor,
    the Order here suggests a different selection of beneficiaries:
    dominant edge providers such as Netflix and Google. See
    Order ¶ 197 n.492.
    Another question posed by the Order but never answered
    is the Commission’s idea that if superior services are priced,
    their usage will track the size and resources of the firms using
    them. One would expect, instead, that firms would pay extra
    for extra speed and quality to the extent that those transit
    enhancements increased the value of goods and services to the
    end user. Firms do not ship medical supplies by air rather
    50
    than rail or truck because the firms are rich and powerful
    (though doubtless some are). They use air freight where
    doing so enhances the effectiveness of their service enough to
    justify the extra cost. This obvious point explains why
    Berninger is a petitioner here.
    The Commission’s disparate treatment of two types of
    prioritization that appear economically indistinguishable
    suggests either that it is ambivalent about the ban itself or that
    it has not considered the economics of the various relevant
    classes of transactions. Or perhaps the Commission is drawn
    to its present stance because it enables it to revel in populist
    rhetorical flourishes without a serious risk of disrupting the
    net.
    Whatever the explanation, the Order fails to offer a
    reasoned basis for its view that paid prioritization is “unjust or
    unreasonable” within the meaning of § 201, or a reasoned
    explanation for why paid prioritization is problematic, or
    answers to commenters’ critiques and alternatives. I note that
    all these objections would be fully applicable even as applied
    to ISPs with market power.
    It is true that the Commission has asserted the conclusion
    that the supposed beneficent effect of its new rules on edge
    providers as a class will (pursuant to its virtuous cycle theory)
    enhance demand for internet services and thus demand for
    broadband access services.         See Order ¶ 410.9         The
    9
    The Commission also makes several other claims about the
    impact of the Order on investment. See Order ¶ 412 (on the
    expected growth in Internet traffic driving investment); Order ¶ 414
    (claiming a lack of the impact of Title II regulation in other
    circumstances); Order ¶ 416 (on indications from a major
    infrastructure provider that it would continue investing under Title
    51
    Commission’s predictions are due considerable deference, but
    when its decision shows no sign that it has examined serious
    countervailing contentions, that decision is arbitrary and
    capricious.
    Accordingly, its promulgation of the rules under § 201 is,
    absent a better explanation, not in accordance with law.
    
    5 U.S.C. § 706
    (2)(A) & (C).
    B
    Alamo-Berninger raise two objections to the
    Commission’s reliance on § 706 of the 1996 Act, 
    47 U.S.C. § 1302
    , as support for its new rules, especially the bans on
    paid prioritization, blocking and throttling (i.e., the statutory
    theory offered by the Commission as an alternative to its
    reliance on § 201). First, Alamo-Berninger develop a
    comprehensive claim that § 706 grants the Commission no
    power to issue rules. Alamo-Berninger Br. 9-16. On its face
    the argument seems quite compelling, see also Pai Dissent, at
    370-75, but I agree with the majority that the Verizon court’s
    ruling on that issue was not mere dictum, but was necessary to
    the court’s upholding of the transparency rules. Maj. Op. 95.
    Second, Alamo-Berninger raise, albeit in rather
    conclusory form, the argument that “the purpose of section
    706 is to move away from exactly the kind of common-carrier
    duties imposed by this Order. Thus . . . the rules [adopted in
    the Order] frustrate the purpose of the statute and are therefore
    unlawful.” Alamo-Berninger Br. 15.
    II). None of these addresses the incremental effects of the specific
    rules that the Commission adopted.
    52
    On this issue, the passages of Verizon giving § 706 a
    broad reading—“virtually unlimited power to regulate the
    Internet,” as Judge Silberman observed in dissent, 740 F.3d at
    662—and endorsing the Commission’s applications of its
    “virtuous cycle” theory, were dicta, as Alamo-Berninger
    argue. Alamo-Berninger Br. 16. With the narrow exception
    of the transparency rules, the Verizon court struck down the
    rules at issue on the ground that they imposed common-carrier
    duties on the broadband carriers, impermissibly so in light of
    
    47 U.S.C. §§ 153
    (51) (providing that a telecommunications
    carrier can be treated “as a common carrier under this [Act]
    only to the extent that it is engaged in providing
    telecommunications services”) & 332(c)(2) (similar limitation
    as to persons engaged in providing “a private mobile
    service”). 740 F.3d at 650. The sole rules not struck down
    were the transparency rules. Although Judge Silberman
    would have upheld them on the basis of 
    47 U.S.C. § 257
    , see
    740 F.3d at 668 n.9, they are equally sustainable as ancillary
    to a narrow reading of § 706, confining it, as Judge Silberman
    would have, to remedying problems derived from market
    power. See id. at 664-67. Of course, on no understanding
    could Verizon provide direct support for the Commission’s
    ban on paid prioritization, as that was not before the court.
    Although the Alamo-Berninger argument here is
    conclusory, the briefing that led to the Verizon dicta was
    extensive, Brief for Appellant Verizon at 28, 31, Verizon, 740
    F.3d; Reply Brief for Appellant Verizon at 14, Verizon, 740
    F.3d, so concern for the Commission’s opportunity to reply is
    no basis for disregarding the issue. The Commission’s
    reliance on § 706 poses questions of both statutory
    interpretation and arbitrary and capricious rulemaking.
    Further, paralleling the inadequacies in the Commission’s
    reliance on § 201(b), the reasonableness of the regulations
    under § 706 is important not only on its own but also for its
    53
    relevance to the reasonableness of reclassification under Title
    II.
    There is an irony in the Commission’s coupling of its
    decision to subject broadband to Title II and its reliance on
    § 706. As the Alamo-Berninger brief argues, § 706 points
    away from the Commission’s classification of broadband
    under Title II and its Order. Alamo-Berninger Br. 15. Title II
    is legacy legislation from the era of monopoly telephone
    service. It has no inherent provision for evolution to a
    competitive market.       It fits cases where all hope (of
    competitive markets) is lost. Section 706, by contrast, as part
    of the 1996 Act and by its terms, seeks to facilitate a shift
    from regulated monopoly to competition.          Indeed, the
    Telecommunications Act of 1996 begins by describing itself
    as
    [a]n Act [t]o promote competition and reduce regulation
    in order to secure lower prices and higher quality services
    for American telecommunications consumers and
    encourage      the    rapid     deployment      of     new
    telecommunications technologies.
    Telecommunications Act of 1996, Pub. L. No. 104-104, 
    110 Stat. 56
    . Two central paradoxes of the majority’s position are
    how an Act intended to “reduce regulation” is used instead to
    increase regulation and how an Act intended to “promote
    competition” is used at all in a context in which the
    Commission specifically forswears any findings of a lack of
    competition.
    On top of the generally deregulatory pattern of the 1996
    Act, a reading of § 706 as a mandate for virtually unlimited
    regulation collides with the simultaneously enacted 
    47 U.S.C. § 230
    . That section is directed mainly at making sure that
    internet service providers and others performing similar
    54
    functions are not liable for offensive materials that users may
    encounter. But it also broadly states that it “is the policy of
    the United States . . . to preserve the vibrant and competitive
    free market that presently exists for the Internet and other
    interactive computer services, unfettered by Federal or State
    regulation.” 
    Id.
     § 230(b)(2). The Commission’s use of § 706
    to impose a complex array of regulation on all internet service
    provision seems a distinctly bad fit with that declared policy.
    Furthermore, consider the specific measures that § 706
    encourages:
    The Commission and each State commission with
    regulatory jurisdiction over telecommunications services
    shall encourage the deployment on a reasonable and
    timely basis of advanced telecommunications capability
    to all Americans . . . by utilizing, in a manner consistent
    with the public interest, convenience, and necessity, price
    cap regulation, regulatory forbearance, measures that
    promote competition in the local telecommunications
    market, or other regulating methods that remove barriers
    to infrastructure investment.
    Section 706(a), 
    47 U.S.C. § 1302
    (a) (emphasis added).
    The two steps expressly favored are both deregulatory.
    Forbearance is obvious; it presupposes statutory authority to
    impose some burden on the regulated firms, coupled with
    authority to relieve them from that burden—and encourages
    the Commission to give relief.
    Price cap regulation needs more explanation. It is
    normally seen as a device for at least softening the deadening
    effects of conventional cost-based rate regulation in natural
    monopolies. Such regulation dulls incentives by telling the
    regulated firm that if it makes some advance cutting its costs
    55
    of service, the regulator will promptly step in and snatch away
    any profits above its normal allowed rate of return. Of course
    there will be a “regulatory lag” between the innovation and
    the regulator’s clutching hand, but the regulatory process
    overall limits the incentive to innovate to a fraction of what it
    would be under competitive conditions. See National Rural
    Telecom Association v. FCC, 
    988 F.2d 174
    , 177-78 (D.C. Cir.
    1993). Price cap regulation, by contrast, looks to general
    trends in the cost inputs for providers, typically building in (if
    trends support it) an assumption of steadily improving
    efficiency. Firms benefit from their innovation except to the
    extent that their successes may bring down average costs
    across the industry. Id.; for some details of application, see
    United States Telephone Association v. FCC, 
    188 F.3d 521
    (D.C. Cir. 1999). So it is easy to see how a shift to price cap
    regulation might be a suitable transition move for a still
    uncompetitive industry. Allowing the firms such benefits
    would invite “advance[s]” in telecommunications capability
    and would “remove barriers to infrastructure investment,”
    which § 706 posits as the goals of agency actions thereunder.
    Section 706’s broad language points in the same direction
    as the two examples. It speaks of removing “barriers to
    infrastructure investment.” Writing in 1996, before the
    Commission developed its virtuous cycle theory, the drafters
    most likely had in mind the well-known barriers erected by
    conventional natural monopoly regulation—not only the bad
    incentive effects of cost-based rate regulation but also hurdles
    such as agency veto power over new entry into markets.
    Section 706 also speaks of measures “that promote
    competition.”      But here the Commission saddles the
    broadband industry with common-carrier obligation, which is
    normally seen as a substitute for competition—as I mentioned
    earlier, for markets where all hope is lost. Where a shipper or
    passenger faces only one carrier, it makes some sense to
    56
    require that carrier to accept all comers, subject to reasonable
    rules of eligibility. This is true even for historic innkeeper
    duties, which seem to presuppose a desperate traveler
    reaching an isolated inn in the dead of night.
    In part II.A I reviewed the distortions likely to flow from
    the Commission’s ban on paid prioritization, but here,
    considering the Commission’s reliance on a statute that seems
    the antithesis of common-carrier legislation, we should
    consider the way the common-carrier mandate may thwart
    competition and thus contradict the purposes of § 706.
    In ordinary markets a firm can enter the field (or expand
    its position) by preferential cooperation with one or more
    vertically related firms. Antitrust law clearly recognizes this
    avenue to enhanced competition.              See XI Herbert
    Hovenkamp, Antitrust Law: An Analysis of Antitrust
    Principles and Their Application ¶ 1811a2 (2006). For
    example, in Sewell Plastics v. Coca-Cola, 
    720 F. Supp. 1196
    (W.D.N.C. 1989), aff’d per curiam, 
    1990-2 Trade Cas. ¶ 69,165
    , 
    912 F.2d 463
     (4th Cir. 1990) (unpublished), the
    court considered under § 1 of the Sherman Act an
    arrangement among Coca-Cola bottlers to buy at least 80% of
    their plastic bottles from a new entrant—a joint venture of the
    bottlers themselves. The object was to circumvent the
    steadily rising prices charged by plaintiff Sewall Plastics, the
    largest supplier of plastic bottles in the country; the joint
    venturers saw the agreement as necessary to assure a steady
    market for their bottle-making operation and thus justify the
    investment, which Sewall could readily have undercut by
    dropping its prices. The court found the agreement pro-
    competitive because it enabled the new entry, which in turn
    lowered prices—just as ordinary economic understanding
    would predict. Speaking of requirements contracts but in
    terms that seem to match other exclusive vertical
    arrangements in workably competitive markets more
    57
    generally, the Supreme Court has said that they are “of
    particular advantage to a newcomer to the field to whom it is
    important to know what capital expenditures are justified.”
    Standard Oil Co. of California v. United States, 
    337 U.S. 293
    ,
    306-07 (1949). Hovenkamp makes the extension explicitly,
    seeing such cases as examples of “the procompetitive use of
    exclusive dealing to facilitate market entry where it might not
    otherwise occur at all.” Hovenkamp ¶ 1811a2, at 153.
    The Commission’s common-carrier mandate, however,
    especially as implemented by the Order’s Internet Conduct
    Standard, poses serious obstacles to comparable efforts by
    ISPs. It prohibits internet providers from “unreasonably
    interfer[ing] with or disadvantag[ing] . . . (1) end users’ ability
    to select, access, and use . . . the lawful Internet content,
    applications, services, or devices of their choice, or (2) edge
    providers’ ability to make lawful content, applications,
    services, or devices available to end users,” Order ¶ 136, and
    is coupled with a multi-factor test, Order ¶¶ 138-145.
    Although the Commission for the moment purports to keep an
    open mind as to a variant of such preferential arrangements
    (“structured data plans”), Order ¶ 152, the Order at minimum
    casts a shadow over such arrangements.
    Of course the Commission is not an antitrust enforcement
    agency. But consider exclusive deals of this sort in relation to
    its virtuous cycle theory. Special deals facilitating new entry
    among ISPs (or expansion of existing small firms) would
    enable investment and growth in broadband, which the
    Commission says is its goal (linked, of course, to the
    flourishing of edge providers). Yet the Commission says,
    without analytical support, that the new rules, generally
    requiring all broadband providers to follow a single business
    model, are just the ticket for broadband growth and
    investment. This seems antithetical to § 706, not to mention
    the post-DARPA decades in which innovative individuals and
    58
    firms spontaneously developed the internet, creating new
    businesses and entirely new types of competition. This model
    of spontaneous creation is, interestingly, the very model of the
    internet sketched out in compelling terms by the FCC’s
    current General Counsel before he assumed that post. See
    Jonathan Sallet, The Creation of Value: The Broadband Value
    Circle and Evolving Market Structures (2011).
    In light of this textual analysis of § 706 and its relation to
    common carriage, and of Judge Silberman’s arguments in
    Verizon, see especially 740 F.3d at 662, and considering the
    rules’ antithetical relation to the goals set forth in § 706, I
    believe that a threshold to application of § 706 is either (1) a
    finding that the regulated firms possess market power or (2) at
    least a regulatory history treating the firms as possessing
    market power (classically as natural monopolies). Under this
    reading of § 706, then, the Commission’s refusal to take a
    position on market power wholly undercuts its application of
    § 706.
    I must now consider the role of § 706 even if we were to
    assume the view taken by the Verizon majority in dicta. Here
    all the problems I discussed as to paid prioritization in part
    II.A come into play, with the record full of highly plausible
    arguments—never so much as acknowledged by the
    Commission—as to the distortions that a ban on paid
    prioritization would generate (especially if made relatively
    coherent by removing the Commission’s puzzling exception
    for caching and other paid peering). The Order fails to give
    any reasoned support for the notion that the ban on paid
    prioritization (or the affiliated and ancillary bans on blocking
    and throttling) would spin the virtuous cycle along and
    thereby promote investment. It does not respond to arguments
    that the ban on paid prioritization would result in increased
    network congestion, less innovation, less investment, and
    worse service, nor explain why alternatives offered in the
    59
    rulemaking would not address the supposed problems with
    less collateral damage.
    In short, the Commission has not taken the initial step of
    showing that its reading of § 706 as a virtually limitless
    mandate to make the internet “better” is a reasonable reading
    to which we owe deference. Entergy Corp. v. Riverkeeper,
    Inc., 
    556 U.S. 208
    , 218 & n.4 (2009). Without such an
    interpretation, the Commission’s rules cannot be sustained
    under § 706, even without regard to the reasoning gaps that
    were a primary subject of part II.A.
    III
    Full Service Network challenges the Commission’s
    decision to forbear from applying a host of Title II’s
    provisions, most particularly 
    47 U.S.C. §§ 251-52
    , on the
    ground (among others) that forbearance, in the absence of a
    showing of competition between local exchange carriers (see
    
    47 U.S.C. §§ 153
    (32), 153(54)), is arbitrary, capricious, and
    contrary to law. I agree to this extent: The Commission’s
    forbearance decision highlights the dodgy character of the
    Commission’s refusal, in choosing to reclassify broadband
    under Title II, to take any position on the question whether the
    affected firms have market power. The upshot is to leave the
    Commission in a state of hopeless self-contradiction.
    In part II I noted that one reason for the Commission’s
    evasion of the market-power question may well have been its
    intuition that the question might (unlike its handwaving about
    the virtuous cycle) be susceptible of a clear answer and that
    that answer would be fatal to its expansive mission. The issue
    raised by Full Service exposes another flaw in the
    Commission’s non-decision.         While a finding that the
    broadband market was generally competitive would, under
    Commission precedent, amply justify its forbearance
    60
    decisions, here again the Commission refuses to take that
    position. Doing so would obviously undermine its decision to
    reclassify broadband under Title II. Strategic ambiguity best
    fits its policy dispositions. But strategic ambiguity on key
    propositions underlying its regulatory choices is just a polite
    name for arbitrary and capricious decisionmaking.
    * * *
    Full Service points out that in justifying application of
    Title II the Commission broadly repudiated its 2005 reliance
    on the emergence of “competitive and potentially competitive
    providers and offerings,” see Order ¶ 330 n.864, saying
    instead that “the predictive judgments on which the
    Commission relied in the Cable Modem Declaratory Ruling
    anticipating vibrant intermodal competition for fixed
    broadband cannot be reconciled with current marketplace
    realities.” Order ¶ 330; in support of this reading of the Cable
    Modem Declaratory Ruling, the Order cites the Wireline
    Broadband Classification Order, 20 F.C.C. Rcd. 14853 ¶ 50
    (2005). Order ¶ 330 n.864; FSN Br. 18. Besides invoking the
    Commission’s conclusory repudiation of its former view, Full
    Service stresses § 251’s pro-competitive purposes, points to
    data accumulated by the Commission that it contends show
    widespread lack of competition among local distribution
    facilities, and argues that the state of competition is highly
    relevant to the Commission’s exercise of forbearance under
    
    47 U.S.C. § 160
    , at least with respect to provisions aimed at
    stimulating competition. FSN Br. 15, 18-20; 
    47 U.S.C. § 160
    (b) (requiring Commission to consider whether
    forbearance “will promote competitive market conditions”);
    cf. Maj. Op. 93-94. Moreover, Full Service specifically ties
    its argument to the statutory requirements, noting that, in 
    47 U.S.C. § 160
    (b), “Congress directed that the FCC evaluate the
    effect of forbearance on competition,” FSN Br. 15, and that
    unbundling requirements were intended to promote
    61
    competition, id. at 20. Full Service dedicates a subsection to
    this argument in its brief, id. at 18-20, concluding that
    Congress’s intent to promote competition, together with
    evidence of a lack of competition nationwide, means that “
    47 U.S.C. § 160
     surely requires more to support forbearance than
    an assertion by the F.C.C. that ‘other authorities’ are adequate
    and the public interest will be better served by enhancing the
    agency’s discretion.” Full Service pursued the same angle in
    oral argument, asserting that “you can’t say that waiving
    Section 251 is about anything but competition, that’s the
    whole purpose of that section.” Oral Arg. Tr. 142.
    
    47 U.S.C. § 251
     requires local exchange carriers to
    provide competitors with various advantages, mostly notably
    “access to network elements on an unbundled basis.” 
    47 U.S.C. § 251
    (c)(3); cf. Order ¶ 417 (referring to such access
    as “last-mile unbundling”). Full Service seeks such access to
    broadband providers’ facilities (governed by the procedures
    set out in § 252 for negotiating these agreements), asserting
    that such access is necessary to its ability to compete in local
    markets for broadband internet. FSN Br. 13; see U.S.
    Telecom Ass’n v. FCC, 
    359 F.3d 554
    , 561 (D.C. Cir. 2004)
    (“The [1996 Act] sought to foster a competitive market in
    telecommunications. To enable new firms to enter the field
    despite the advantages of the incumbent local exchange
    carriers (“ILECS”), the Act gave the Federal Communications
    Commission broad powers to require ILECs to make ‘network
    elements’ available to other telecommunications carriers.”).
    As we shall see, the Commission’s reasoning in the Order
    resembles that of the Environmental Protection Agency in
    Utility Air Regulatory Group v. EPA, 
    134 S. Ct. 2427
     (2014)
    (“UARG”). There the Agency interpreted certain permitting
    requirements under the Clean Air Act to apply to greenhouse
    gases, but acknowledged that applying the thresholds that
    Congress specified in the relevant sections would regulate too
    62
    many firms and create unacceptable costs. The agency
    therefore relied on its power to interpret ambiguous statutory
    terms to “tailor” the requirements, increasing the permitting
    thresholds from 100 or 250 tons to 100,000 tons (i.e., three
    orders of magnitude). 
    Id. at 2444-45
    . The Court held that the
    agency’s combined choice—construing an ambiguous
    statutory provision to apply while dramatically reducing its
    substantive application—was unreasonable. In so holding, it
    “reaffirm[ed] the core administrative-law principle that an
    agency may not rewrite clear statutory terms to suit its own
    sense of how the statute should operate.” 
    Id. at 2446
    .
    The Commission violates that core principle here, where
    it seeks to apply Title II to broadband internet providers while
    forbearing from the vast majority of Title II’s statutory
    requirements. As did EPA in UARG, though perhaps with
    less candor, the Commission recognizes that the statutory
    provisions naturally flowing from reclassification of
    broadband under Title II do not fit the issues posed by
    broadband access service. “This is Title II tailored for the
    21st Century. Unlike the application of Title II to incumbent
    wireline companies in the 20th Century, a swath of utility-
    style provisions (including tariffing) will not be applied. . . . In
    fact, Title II has never been applied in such a focused way.”
    Order ¶ 38.
    Although the 1996 Act requires the Commission to
    forbear from application of any of the provisions of Title 47’s
    Chapter 5 when the conditions of 
    47 U.S.C. § 160
    (a) are met,
    Pub. L. 104-104, Title IV, § 401 (Feb. 8, 1996), the
    Commission’s massive forbearance, without findings that the
    forbearance is justified by competitive conditions,
    demonstrates its unwillingness to apply the statutory scheme.
    Even if the Commission’s forbearance itself were reasonable
    standing alone, that forbearance, paired with the
    reclassification decision, was arbitrary and capricious. Or, to
    63
    note the reverse implication, the massive, insufficiently
    justified forbearance infects the decision to apply (or purport
    to apply) Title II. The logical inconsistency is fatal to both.
    (The Commission offers no opposition to USTA’s contention
    that reclassification and forbearance are intertwined and
    therefore stand or fall together. USTA Intervenor Br. 21.)
    While the statute explicitly envisions forbearance, it does
    so only under enumerated conditions. To forbear, the
    Commission must determine that enforcement of a provision
    is not necessary to ensure just, reasonable, and
    nondiscriminatory charges and practices or to protect
    consumers, 
    47 U.S.C. § 160
    (a)(1)-(2), and that forbearance “is
    consistent with the public interest,” 
    id.
     § 160(a)(3). In making
    these determinations, “the Commission shall consider whether
    forbearance from enforcing the provision or regulation will
    promote competitive market conditions, including the extent
    to which such forbearance will enhance competition among
    providers of telecommunications services.” Id. § 160(b).
    These conditions are broadly framed, but the emphasis on
    consumer protection, competition, and reasonable,
    nondiscriminatory rates is plainly intended to implement the
    1996 Act’s policy goal of promoting competition in a context
    that had historically been dominated by firms with market
    power, while assuring that consumers are protected.
    The Commission relied in part on the idea that
    enforcement of unbundling rules would unduly deter
    investment, specifically that such enforcement would collide
    with its “duty to encourage advanced services deployment.”
    Order ¶ 514. But, perhaps recognizing that this concern
    would apply universally to compulsory unbundling, the
    Commission also confronted claims that broadband providers
    often have local market power. But it responded to these
    claims not with factual refutation but with an assertion that
    “persuasive evidence of competition” is unnecessary as a
    64
    predicate to forbearance. Order ¶ 439. This assertion is in
    line with the Commission’s view that, “although there is some
    amount of competition for broadband Internet access service,
    it is limited in key respects.” Order ¶ 444. The language is
    sufficiently vague to cover any state of competition between
    outright monopoly and perfect competition.
    The Commission claimed that its current forbearance
    matches its past practice, offering a list of orders in which it
    forbore while giving competition little or no consideration.
    Id. ¶ 439 n.1305 (listing cases). But the cited orders do not
    vindicate the Commission. They fall into three groups: (1)
    orders forbearing from provisions not directly involving
    economic issues at all, such as reporting requirements, (2)
    orders of clear economic import but with no evident
    relationship to competition, and (3) orders evidently related to
    competition where the Commission analyzed competition
    intensely.
    The first group is easily addressed. The Commission’s
    grant of forbearance from seemingly noneconomic
    requirements is irrelevant to the arbitrariness of its
    forbearance from a provision aimed precisely at fostering
    competition.
    The second set of orders posed economic concerns but no
    evident link to competition.               In In re Iowa
    Telecommunications Services, Inc., 17 F.C.C. Rcd. 24319
    ¶¶ 17-18 (2002), the Commission granted forbearance to
    replace one set of rates with a different set of rates based on
    forward-looking cost estimates that it believed better reflected
    the petitioner’s operating costs; no finding of competition was
    necessary to guide that replacement. In In re Petition for
    Forbearance from Application of the Communications Act of
    1934, As Amended, to Previously Authorized Servs., 12 F.C.C.
    Rcd. 8408 (1997), the Commission forbore from § 203(c),
    65
    allowing the petitioner to refund excess charges to consumers.
    As the Commission pointed out in that brief order,
    forbearance served consumers and the public interest, since
    consumers would receive the refund. Id. ¶ 10.
    The Commission’s use of the third group suggests that its
    opinion-writing staff was asleep at the switch. The group
    comprises three rulings, In re Implementation of Sections 3(n)
    & 332 of the Communications Act, 9 F.C.C. Rcd. 1411
    (1994),10 In re Petition of Qwest Corp. for Forbearance
    Pursuant to 
    47 U.S.C. § 160
    (c) in the Omaha Metro.
    Statistical Area, 20 F.C.C. Rcd. 19415 (2005), and In re
    Petition of Qwest Corp. for Forbearance Pursuant to 
    47 U.S.C. § 160
    (c) in the Phoenix, Arizona Metro. Statistical
    Area, 25 F.C.C. Rcd. 8622 (2010). Yet in each decision the
    Commission conducted a detailed analysis of the state of
    competition. See 9 F.C.C. Rcd. 1411 ¶¶ 135-54 (considering
    numbers of competitors, falling price trends, etc., and
    concluding that “all CMRS service providers, other than
    cellular service licensees, currently lack market power,” id. at
    ¶ 137, and, after an extensive recounting of factors, making a
    cautious finding that it could not find cellular “fully
    competitive,” id. at ¶ 154); 20 F.C.C. Rcd. 19415 ¶¶ 28-38
    (analyzing market shares, supply and demand elasticity, and
    firm cost, size and resources to assess competition); 25 F.C.C.
    Rcd. 8622 ¶¶ 41-91 (assessing whether incumbent firm had
    market power by careful consideration of market definition,
    10
    This order was later quashed by another order, In re Petition of
    Arizona Corp. Comm’n, to Extend State Authority Over Rate and
    Entry Regulation of All Commercial Mobile Radio Services & In re
    Implementation of Sections 3(N) & 332 of the Communications Act,
    10 F.C.C. Rcd. 7824 (1995). Unsurprisingly, that order also
    contains a detailed market analysis. See, e.g., id. at ¶¶ 42-68.
    66
    factors affecting competition, assessment of the effects of
    SSNIPs).
    I am in no position to assess the quality of these analyses,
    but the entire batch of decisions cited in Order ¶ 439 n.1305
    provides no support for the idea (indeed, undermines the idea)
    that the Commission has an established practice of neglecting
    market power in deciding whether to forbear from a provision
    such as § 251. (I discuss below an interesting exception, the
    order reviewed in EarthLink v. FCC, 
    462 F.3d 1
     (D.C. Cir.
    2006).)
    Given the Commission’s assertions elsewhere that
    competition is limited, and its lack of economic analysis on
    either the forbearance issue or the Title II classification, the
    combined decisions to reclassify and forbear—and to assume
    sufficient competition as well as a lack of it—are arbitrary and
    capricious. The Commission acts like a bicyclist who rides
    now on the sidewalk, now the street, as personal convenience
    dictates.
    The inaptness of the Order’s ¶ 439 n.1305 citations of its
    prior decisions is confirmed by forbearance decisions that
    have reached this court. In U.S. Telecom, 
    359 F.3d at 578-83
    ,
    for example, we considered the Commission’s decision to
    forbear from unbundling requirements for the high-frequency
    portion of copper and hybrid loops for broadband (but not
    from unbundling requirements for the narrowband portion of
    hybrid loops). In reviewing that forbearance decision, which
    was far narrower than the forbearance before us today, we
    gave detailed consideration to the Commission’s analysis of
    the likely effects of more limited unbundling on both
    investment and competition.        We concluded that this
    forbearance was not arbitrary and capricious partly because
    the Commission had offered “very strong record evidence” of
    “robust intermodal competition from cable [broadband]
    67
    providers,” who maintained a market share of about 60%. 
    Id. at 582
    . Both we and the Commission took for granted that
    findings of competition were central to any such forbearance
    decision. The Commission justified its forbearance in terms
    of competition: “A primary benefit of unbundling hybrid
    loops—that is, to spur competitive deployment of broadband
    services to the mass market—appears to be obviated by the
    existence of a broadband service competitor with a leading
    position in the marketplace.” In re Review of the Section 251
    Unbundling Obligations of Incumbent Local Exch. Carriers,
    18 F.C.C. Rcd. 16978 ¶ 292 (2003). Now, when forbearing
    from unbundling requirements far more broadly, the
    Commission asserts that no findings of competition are
    necessary. Rather than justifying its change in position, it
    denies having made any change.
    It is unnecessary, in concluding that the Commission has
    failed to meet its State Farm obligation to reconcile its
    reclassification and forbearance decisions, to resolve whether
    the Commission has adequately considered competition for
    purposes of 
    47 U.S.C. § 160
    (b). See Order ¶¶ 501-02. The
    Commission’s difficulty, in its mentions of competition, lies
    in its attempts to have it both ways. It asserts that there is too
    little competition to maintain the classification of broadband
    as an information service (remember, that is the sole function
    of its discussion of switching costs), but (implicitly) that there
    is enough competition for broad forbearance to be appropriate.
    This sweet spot, assuming the statute allows the Commission
    to find it, is never defined.
    In responding to Full Service’s narrow claim—that the
    Commission was required to do a competition analysis market
    by market—the Commission relies on our decision in
    EarthLink v. F.C.C., 
    462 F.3d 1
    , 8 (D.C. Cir. 2006), where
    indeed we rejected a claim that forbearance from unbundling
    68
    under 
    47 U.S.C. § 271
     required such an analysis. On that
    narrow issue, EarthLink fully supports the Commission.
    But there are considerable ironies in the Commission’s
    supporting its Order here by pointing to Earthlink and the
    order reviewed there. The current Order manifests a double
    repudiation of the one under review in EarthLink: first, it now
    rejects its former interpretation of § 706, and second, it
    reflects the Commission’s complete abandonment of its views
    on the force of intermodal competition.
    In the Earthlink order, the Commission invoked § 706 for
    the proposition that relieving local distribution companies
    from regulation would encourage investment, and thus would
    let competition bloom, sufficiently to offset any loss to
    competition from refusing to order unbundling. Now, of
    course, the Commission invokes § 706 for the idea that
    saddling such firms with regulation will encourage
    investment.
    And in the Earthlink order the Commission relied on its
    now repudiated idea that intermodal competition would play a
    big role in assuring adequate competition. See 
    462 F.3d at 7
    ,
    citing Petition for Forbearance of the Verizon Telephone
    Companies Pursuant to 
    47 U.S.C. § 160
    (c), 19 F.C.C. Rcd.
    21,496 ¶¶ 21-23.          Now, without undertaking the
    inconvenience of a market power analysis, the Commission
    has rendered its confidence in intermodal competition
    “inoperative” (to borrow a phrase from the Watergate
    proceedings) for purposes of reclassification, but (perhaps)
    not for unbundling.
    In sum, the Commission chose to regulate under a Title
    designed to temper the effects of market power by close
    agency supervision of firm conduct, but forbore from
    provisions aimed at constraining market power by compelling
    69
    firms to share their facilities, all with no effort to perform a
    market power analysis.               The Order’s combined
    reclassification-forbearance decision is arbitrary and
    capricious.
    * * *
    The ultimate irony of the Commission’s unreasoned
    patchwork is that, refusing to inquire into competitive
    conditions, it shunts broadband service onto the legal track
    suited to natural monopolies. Because that track provides
    little economic space for new firms seeking market entry or
    relatively small firms seeking expansion through innovations
    in business models or in technology, the Commission’s
    decision has a decent chance of bringing about the conditions
    under which some (but by no means all) of its actions could
    be grounded—the prevalence of incurable monopoly.
    I would vacate the Order.
