1.  Introduction

   The Internet as part of the critical infrastructure affects many
   aspects of our society significantly, although it impacts different
   parts of society differently.  The Internet is an important tool to
   reach the Sustainable Development Goals (SDG) [SDG] and to globally
   support human rights.  Consequently, the lack of meaningful access to
   digital infrastructure and services is also a form of
   disenfranchisement.

   Solely having Internet access is not enough.  At the same time as we
   work to connect the next billion people and reduce the digital
   divide, it is also important to understand persistent and novel
   inequalities in the digital age when accessing content and services.
   There are more and more barriers to meaningful access to the services
   and applications that run on the Internet.  Even if Internet
   connectivity is available, information and service access may remain
   challenged and unequal.

   This IAB workshop has aimed

   *  to collect reports about barriers to accessing content and
      services on the Internet, e.g. based on filtering, and blocking as
      well as due to general inequality of technological capabilities,
      like device or protocol limitations.

   *  to help the Internet community get a better understanding of how
      the Internet functions in different parts of the world and which
      technology or techniques need to be used to gain access to
      content.

   *  to build an understanding of what “being connected” to the
      Internet means: What is the Internet to users?  What is needed to
      be meaningfully connected?  What are the minimum requirements to
      be able to access certain parts of the content and services
      provided over the Internet?

2.  Workshop Scope and Discussion

   The workshop was organized across three days with all-group
   discussion slots, one per day.  The following topic areas were
   identified and the program committee organized paper submissions into
   three main themes for each of the three discussion slots.  During
   each discussion, those papers were presented sequentially with open
   discussion held at the end of each day.

2.1.  Session 1: Community Networks - Their Role in Internet Access of
      Services

   The first day of the workshop focused on the role of Community
   Networks [RFC7962] as a way to overcome the barriers to Internet
   Access.  Community Networks are self-organized networks wholly owned
   by the community and thus provide an alternative mechanism to bring
   connectivity and internet services to those places that lack
   commercial interest.

   Presentations ranged from highlighting the need for measuring Quality
   of Experience (QoE) for Community Networks, to the potential role the
   Content Delivery Network (CDN) can play in Community Networks, to the
   role of Satellite Networks, and finally, to the vital role of the
   spectrum in this space.

2.1.1.  The Quality of Community Networks

   [MARTINEZ] highlighted the need to address Quality of Experience
   (QoE) in discussions around Community Networks.  As a community-
   driven deployment, the knowledge and involvement of individuals can
   vary; therefore, there are no guarantees of connectivity or quality
   of service.  There is a need to focus on user expectations and how
   they translate to measurable performance indicators.  Further, it
   asks for better documenting best practices in deploying community
   networks as well as considering manageability considerations for
   community networks in protocol development.  [GUIFI] as an example
   Community Network was discussed and some existing resources for
   Community Networks ([APC], [ISOC], and [TBB]) were shared by the
   participants.

Internet-Draft            BIAS Workshop Report                 June 2024

   The inconsistent quality and performance of Satellite Internet is a
   gap for community networks that rely on non-terrestrial networks
   (NTNs) for internet access [HU].

2.1.2.  Strengthening Community Networks

   [BENSON] focused on the prohibitive cost of the transit and Internet
   service for Community Networks and argued for Content Delivery
   Networks (CDNs) to provide transit-like and Internet services at no
   more than at-cost in a mutually beneficial way.  Community networks
   still need backhaul to and from the CDN’s point of presence and
   models for community-backhaul and open-source CDNs were highlighted.
   Discussion included [PANGEA] project status as well as legal and
   commercial considerations in such use of CDNs.

   [HU] highlighted that Satellite Internet provided by advanced LEO
   satellite constellations can play a pivotal role in closing the
   connectivity gap in the urban-rural digital divide via Satellite-
   dependent community networks.  These existing known performance and
   management gaps need focus to enable Satellite Internet to resolve
   the divide.  Further, research directions such as multi-layer
   satellite networking, autonomous maintenance, and integration between
   Terrestrial and Non-Terrestrial networks were suggested.

   [RENNO] called attention to the coveted 6GHz (part of the C-band with
   a desirable mix of coverage and capacity) as a prime choice for
   International Mobile Telecommunication (IMT) for 5G technology while
   it is in common unlicensed use in the community networks (and small
   ISPs).  Spectrum allocations directly impact industries and market
   access with ramifications for community networks.  Further, there was
   a discussion on the geopolitical tension because of it.

2.1.3.  Discussion

   How can the technical community address the management gap and
   improve best practices for Community Networks?  Is the increasing
   complexity of the Internet making it more challenging to establish
   secure connections, and should this be taken into account in the
   design of the Internet?  What steps need to be taken to make sure
   Community Networks are secure?  Should the manageability
   consideration be expanded to explicitly consider Community Networks?
   Global Access to the Internet for All (GAIA) [GAIA] research group
   could be a venue for further discussion and research.  Further
   discussion highlighted the need for readily available knowledge and
   tools for community networks as well as the tussle with market forces
   when commercial networks compete with community networks.  Also,
   there is a lack of operational inputs from community network
   operators in the IETF/IRTF.

2.2.  Session 2: Digital Divide - Reports and Comments

   Critical internet infrastructure affects many aspects of our society
   significantly, although differently, the inequitable aspects of which
   are typically referred to as "digital inclusion" signifying that in
   efforts to digitalise society, there are those left out due to what
   is typically called the "digital divide", a related term specific to
   access to the Internet.  These concepts together demonstrate that
   even if Internet connectivity is available, for some there will
   remain challenges towards achieving equality.  This becomes
   especially significant as governments view the Internet as an
   important tool to help them reach the Sustainable Development Goals
   (SDG) [SDG] and to globally support human rights.

   The second day of workshops was essential to understanding the nature
   of the digital divide.  Presentations of reports interrogated at
   least three key aspects of the digital divide, though there is
   recognition that there may be more technical aspects of the digital
   divide that were not present.  Those were: differences between
   population demographics in the provision of online resources by
   governments, inequality in the use of multilingualized domains and
   email addresses, and increased costs for end-user downloads of
   contemporary websites' sizes.

2.2.1.  Disparities in service provision

   Ralph Holz presented research that exposes the more limited DNS-
   mediated access to government websites by Indigenous communities in
   Australia as compared to less disadvantaged users in the same
   population in "Evidence for a digital divide?  Measuring DNS
   dependencies in the context of the Indigenous population of
   Australia".  [HOLZ] DNS dependency trends were analysed between two
   lists of domains serving Australian government sites for Indigenous
   users and the general population.  Researchers found, "evidence that
   dependencies for the Indigenous population are indeed differently
   configured," indicative of a difference in service provisioning.
   However qualitative follow-up research is needed to interrogate both
   the potential reasons for these differences and whether the
   differences contribute to a "digital divide" that is tangible for
   Indigenous users.

2.2.2.  Lack of consistent acceptance of language scripts

   On the topic of availability of Internet services and content in
   multiple languages "Universal Acceptance of Domain Names and Email
   Addresses: A Key to Digital Inclusion" was presented by Sarmad
   Hussain of ICANN.  [HUSSAIN] The ICANN community has increased the
   options for multilingual identifiers through the expansion of the
   Internet’s DNS for use in domains and email addresses.  However,
   while the work of technical specification and policy recommendations
   is complete, much work remains to deploy a multiligualized internet.
   Today there are around 150 internationalised domain names (IDNs) but
   the barriers to equal rollout of these scripts at the domain level
   are hindered primarily by software and applications that do not yet
   recognise these new scripts.  "Universal Acceptance" is a programme
   of action for the internet community at large that can ensure IDNs
   are accepted and treated consistently.

2.2.3.  Web Affordability and Inclusiveness

   In "A Framework for Improving Web Affordability and Inclusiveness"
   Rumaisa Habib presented research on the connection between website
   size and cost to end users.  [HABIB] This critical inquiry presents
   access in terms of affordability and through measurement demonstrates
   that the material costs to end users who pay for their connection
   based on the volume of data they download and upload have risen as
   the complexity of the web grows.  Their research provides a framework
   for optimisation based on end-user affordability.  This framework is
   anchored to reality: it proposes a fairness metric and suggests
   systematic adaptations to Web complexity based on "geographic
   variations in mobile broadband prices and income levels."

2.2.4.  Discussion

   These three reports discuss very different aspects of current
   inequalities in Internet access in various parts of the world:
   service provision, availability, and economic costs.  Notably, the
   reports discuss trends that exacerbate the digital divide beyond the
   question of connectivity or whether users have access to the
   Internet, potentially bringing concrete ways that the IETF community
   can address digital inclusion within its remit.

   Discussants noted that while there are some interesting aspects to
   the problem of the digital divide, such as measurements and
   frameworks, most of the work is getting this work to the right people
   at the policy layer so there is an importance of communicating this
   technical evidence to the right people.  The IETF's role could be to
   build consensus on the proper solutions presented to decision-makers
   that put research and measurement not only in context but also in a

Kühlewind, et al.       Expires 22 December 2024                [Page 7]
Internet-Draft            BIAS Workshop Report                 June 2024

   consensus-driven solution space.  Another method to better
   communicate this research is by telling stories of end users in more
   relatable and relevant terms, which is often a challenge for the
   technical level and a role for more diverse stakeholders at the more
   local level.

2.3.  Session 3: Censorship - Reports and Circumvention

   This session focused on reports of censorship as observed during
   recent years in different parts of the world, as well as on the use
   of and expectation on censorship circumvention tools, mainly the use
   of secure VPN services.

   The censorship reports, with a focus on Asia, and specifically India,
   as well as Russia, as an example where censorship has changed
   significantly recently, discussed the legal frameworks and court acts
   that put legal obligations on regional network providers to block
   traffic.  Further, measurements to validate the blocking as well as
   analyses of how blocking is implemented were discussed, i.e. which
   protocols are used but also which kind of devices are used to
   configure the blocking rules and where are they deployed.

2.3.1.  Censorship Orders, Measurements, and Device Analysis

   [SAMSUDIN] reported on confirmed blocking from 10 countries
   (Cambodia, Hong Kong (China), India, Indonesia, Malaysia, Myanmar,
   Philippines, Thailand, Timor-Leste, Vietnam) in the period from 1
   July 2022 to 30 June 2023.  The blocking was either confirmed by OONI
   measurements for existing blocking fingerprints, heuristics, i.e. for
   new blocking fingerprints as well as news reports of blocking orders,
   or user experiences.  Most of these countries block specific content
   such as porn, gambling, or certain news pages.  Interestingly the
   blocking in Hong Kong and Myanmar is focused on the military and
   governmental pages of foreign countries.  Blocking is often realized
   by either DNS tampering or HTTP tampering.  For DNS, either a decided
   IP address, a bogon IP address (127.0.0.1), or an empty domain
   (nxdomain) is used.  In case of DNS tampering using a decided IP
   address or HTTP tampering some countries provide a block page that
   exposes the blocking, however, more transparency about blocking is
   requested by civil society organizations and the iMAP project.

   [GROVER] further focused the discussion on online censorship in
   India, Pakistan, and Indonesia.  In India, where providers are
   responsible for implementing the blocking but no method is mandated,
   the six major ISPs (covering 98.82% of all subscribers) were tested
   on 4379 blocked websites (based on court orders, user reports, and
   publicly available or leaked government orders) on DNS poisoning/
   injection or HTTP/SNI-based censorship.  Used censorship techniques

Kühlewind, et al.       Expires 22 December 2024                [Page 8]
Internet-Draft            BIAS Workshop Report                 June 2024

   and websites blocked were different across ISPs.  Multiple ISPs used
   two different techniques (depending on the website), and all but one
   provided censorship notices.  Providers blocked between 1892 to 3721
   (of 4379) pages with only 1115 (27.64%) of pages blocked by all ISPs.
   [Singh2020] In contrast, in Pakistan, the government can also order
   the IPSs to perform blocking and blocking has even been observed in
   the past on the IXP level.  Since 2020, there has also been a central
   Web Monitoring System deployed at lines of international
   connectivity.  In Indonesia, initially, the government guided ISPs in
   how to perform the blocking.  The regulations were updated in 2020 to
   allow Indonesian ISPs to block websites at their discretion.  In
   2022, there was a proposal by internet service providers to
   centralise DNS.  In Indonesia, a partial block list is publicly
   available, but without any indication of why something is blocked.
   [Grover2023]

   [BASSO] reported that for Russia a high increase in additions to the
   Roskomnadzor’s block list was observed in March 2022 as well as in
   December 2022, foremost covering news pages but also covering human
   rights organizations and social media, where more than 3500 blocking
   orders were added to the list by an "Unknown body".  Further,
   blocking of domains that are not in the official Roskomnadzor’s list
   has been observed as well.

   An invited talk presented the work in [WANG] on locating censorship
   devices by using HTTP and TLS traceroutes, identifying device vendors
   through fingerprinting, and reverse-engineering censorship triggers
   by the use of fuzzing.  E.g. for the case of Azerbaijan and
   Kazakhstan, they showed that a significant portion of measurements
   from remote countries are blocked at the endpoint, indicating local
   policies but connection resets are also happening in Belarus and
   Russia.  Further, they could identify a set of commercial network
   devices (with filtering techniques such as firewalls) that are used
   in these countries for censorship and show how fuzzing can be used to
   fingerprint and cluster behaviours as well as potentially circumvent
   the deployed methods.

   All speakers called for more transparency by requiring blocking
   messages as well as publication and auditing of blocklists.
   Potentially even standardization could help.

2.3.2.  Use of VPNs for Censorship Circumvents and User Expectations

   Further on in the session, the possibility and prevalence of using
   VPNs for circumvention has been discussed including user expectations
   and an analysis of security shortcomings of commercial VPN services.
   The analysis presented in [RAMESH] has shown various problems that
   lead to data leaks such as leakage of IPv6 traffic, non-browser
   traffic, or tunnel failure, not upholding user expectations,
   especially when used in authoritarian regimes for censorship
   circumvention or private communication.

   The question of how common the use of VPNs for circumvention is and
   its legal implications, as VPNs are illegal in a few countries, has
   been discussed.  E.g.  VPNs are not officially banned in India but
   VPN providers need to store log data and those, who haven’t complied,
   stopped serving India.  However, more data on VPN use and blocking
   might be needed.

2.3.3.  Discussion

   After all, there is a cat-and-mouse game between censors and
   circumvents, however, continued work on protocol enhancements that
   protect user privacy is essential.

2.4.  Key Take Aways

   Some key takeaways from the workshop are -

   *  There is a need for the technical community to address the
      management gaps in operating Community Networks.

   *  Work should be done in documenting best practices for operating
      Community Networks.

   *  During the development of protocols, explicit manageability
      considerations related to Community Networks should be considered.

   *  Build consensus on solutions that have the most significant impact
      in fostering digital inclusion.  Further, promoting these
      solutions ensures that efforts to bridge the digital divide are
      effective and inclusive.

   *  Further work to enhance protocols ensuring user privacy should
      continue.

   *  Develop further protocols (or extensions to existing protocols)
      that enable more transparency on filtering and promote their use
      and deployment.

Internet-Draft            BIAS Workshop Report                 June 2024

   *  Develop new VPN-like services and potentially support measurements
      to understand their deployment and use.

   *  Further discussion of these topics could happen in GAIA, HRPC,
      PEARG, and MAPRG based on the relevance to the research group.
      The management and operations-related discussion can be taken to
      OPSAWG.  The community could also explore if a censorship (and its
      circumvention) focused group could be created.

Appendix A.  Position Papers

   19 position papers were submitted to the workshop call for papers. 11
   were selected for publication.  Papers that were not published either
   (1) only provided a very prelimited analysis of an idea that was felt
   to be incomprehensive for discussion at the workshop, or (2)
   addressed problems that were beyond the scope as dedicated for the
   workshop discussion e.g. discussing cyber security threads as a
   barrier for participation or implication of technology in regulation
   that imposes blocking.  Both of these topics pose a potentially
   severe risk on the open Internet, however, these risks might provide
   a high risk for all Internet users but do not necessarily imply an
   unbalance.
