TAS Interruption - Update (9 May 2012)

Statement by Akram Atallah, COO

As we announced yesterday, ICANN has provided notice to all users to let them know whether they may have been affected by the technical glitch in the TLD application system, or TAS.

We sent an email [PDF, 41 KB] to each TAS user asking them to log in to the notification system and view whether they may have been affected. Notifications were delivered to the 1,275 registered TAS users in four categories.

The categories, along with links to the corresponding notification template, break down as follows:

  1. Users who did not have file names or usernames viewed [PDF, 72 KB]: 1,163
  2. Users who had one or more file names and/or user names that may have been viewed by another user [PDF, 73 KB]: 72.
  3. Users who may have seen the file names and/or usernames of one or more other users [PDF, 73 KB]: 30.
  4. Users who had one or more file names and/or user names that may have been viewed, and who also may have been able to see file name and/or username information of other users [PDF, 75 KB]: 10.

Users whose file names and/or user names may have been viewed were provided with the details of the relevant information.

As we announced yesterday, we are targeting 22 May 2012 as the intended reopening date for TAS, and anticipate a 30 May closing.

We understand and regret the inconvenience that the glitch has caused.

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""icann.org"" is not an IDN."
