An Update from the SSR2 Review Team

The second Security, Stability, and Resiliency (SSR2) Review Team continues to progress its assessment of how well ICANN is executing its commitment to enhance the operational stability, reliability, resiliency, security, and global interoperability of the Internet's system of unique identifiers.

Along with the rest of the world, the COVID-19 pandemic has disrupted our work. While we are making progress in virtual sessions, the inability to meet face-to-face as planned in March and May 2020 has impacted our timeline. We expect to complete our review and submit our final report to the ICANN Board in October 2020.

We are currently in the process of considering the public comments that we received on our draft report [PDF, 1.1 MB]. As you can see from the Public Comment staff report [PDF, 348 KB], we received 18 public comment submissions, totaling close to 400 individual comments.

Our focus in the coming months will be to work toward producing a final report that reflects the constructive feedback that was provided by the community. While we do not expect to accept every comment, we are working diligently to ensure that we consider all of the diverse perspectives offered. Our final report will include a detailed explanation of how we considered the public comments and the rationale for the decisions we reached. We plan to host a webinar near the time that the final report will be published to inform the community of any updates.

The SSR2 Review is a community-led review that operates with full transparency. You can follow the review team meetings live and stay informed of its progress by becoming an observer, or feel free to ask any of our team members to provide an update to your constituency.

    Domain Name System
    Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
