Guideline
ICANN has established a Customer Standing Committee (“CSC”) (Article 17 of the ICANN Bylaws) to monitor the performance of the Post Transition IANA (PTI) entity under the IANA Naming Function Contract and IANA Naming Function Statement of Work (SOW).
The mission of the CSC is to ensure continued satisfactory performance of the IANA naming function for the direct customers of the naming services. The primary customers of the naming services are top-level domain registry operators, but also include root server operators and other non-root zone functions.
The CSC will achieve this mission through regular monitoring of the performance of the IANA naming function against the IANA Naming Function Contract and IANA Naming Function SOW and through mechanisms to engage with PTI to remedy identified areas of concern. According to Article 17, the ccNSO shall appoint two (2) members of the CSC to represent ccTLD operators. In addition, under Article 17 the ccNSO and the GNSO together may, but need not, appoint one (1) additional member of the CSC representing top-level domain registry operators that are considered neither a ccTLD nor a GTLD.
