TAS Reopens

Statement by Akram Atallah, COO

The TLD Application System, or TAS, has reopened. All registered applicants can now log in, review and submit their applications.

The system will remain open until 23:59 GMT/UTC on 30 May 2012. Consistent with our previous practice and to allow the application window to open as soon as possible, two-hour maintenance windows have been scheduled as follows: 22 May at 16:30 GMT/UTC, 25 May at 23:00 UTC, and 29 May at 22:00 UTC.

Applicants are encouraged to review "Top Things Users Should Know When TAS Reopens," posted on the new gTLD microsite at The document provides advice on logging into and completing applications, submitting wire transfers, and contacting customer service with any issues users might encounter.

During the last few weeks, we have fixed the technical glitch that caused us to take the system offline. Also, to address user feedback, we have improved the overall system performance and the HTML preview function.

In our continuing review of the system logs and system traffic, we determined that in two instances, a single file might have been temporarily unavailable to an applicant. Full access to those two files has been restored. ICANN notified the affected users.

We recognize and regret the inconvenience caused by this glitch and the delayed closing of the application window.

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."
