ICANN’s Interim Trust Anchor Repository (ITAR), designed to help move DNSSEC deployment forward before the root zone was signed, is now being retired.  As of November 4, no new listings will be accepted. Existing listing are expected to be removed around November 18, and the entire service will stop in January 2011, ICANN announced.

Dozens of early DNSSEC-adopting top-level domain operators were able to use the ITAR to publish their trust anchor in absence of a signed DNS root zone. ICANN notes that the ITAR supported more than 100 such listing requests during its lifetime.
