Procedures for IDN TLD Evaluation Deployment in the Root Zone

6 August 2007

ICANN has finalized the procedures describing how IANA will manage the insertion, administration and removal of internationalized top- level domains in the root zone for the upcoming evaluation. The procedures were posted previously for public comments. That comment, as well as advice from the technical community (including RSSAC), was taken into consideration in editing the final versions.

The two procedures guiding this effort are:

1. IANA Root Zone Procedures for Test IDN Deployment

The final procedure was approved by the ICANN Board on 29 June 2007 (see http://icann.org/minutes/resolutions-29jun07.htm) after some clarifications were provided in response to public comment (see http://forum.icann.org/lists/iana-idn-process/). These procedures are being implemented by IANA in preparation for the insertion of IDN evaluation TLDs.

2. Root Server Operator Procedures for Emergency Revocation of Evaluation-purpose IDN TLDs

The purpose of this procedure is to provide a method of quickly removing IDN TLDs from the root zone in the very unlikely event that insertion of these evaluation strings negatively impact DNS or root server operations. After consultation with the RSSAC, the procedure has been modified to focus on a communication protocol that root server operators will employ in the identification and mitigation of any problems that might arise for root server operations as a consequence of the proposed testing of IDN strings . Root server operators will monitor and identify deteriorated service potentially caused by IDNs in the root. If such a result is detected, ICANN will be notified and in turn activate the procedure.

IDN Program -- looking forward: The next milestones in the IDN Program Plan requires obtaining necessary approvals to insert the eleven suggested evaluation top-level domains (the term <.test> translated into eleven languages). (See the IDN .test Evaluation Plan at http:// icann.org/announcements/announcement-2-19jun07.htm). An additional announcement will be made once the approvals have been received. It is anticipated that these evaluation TLDs will be launched in late September 2007.
