The final rollout of DNSSEC to the internet’s root servers, a major security upgrade for the domain name system, has been pushed back two weeks to July 15.
ICANN’s DNS director Joe Abley said in an update on root-dnssec.org and in email to the dns-ops mailing list:
The schedule change is intended to allow ICANN and VeriSign an additional two weeks for further analysis of the DURZ rollout, to finalise testing and best ensure the secure, stable and resilient implementation of the root DNSSEC production processes and systems.
The Deliberately-Unvalidatable Root Zone is a way for the root operators to test how normal DNS resolution copes with fatter DNSSEC responses coming from the root, before worrying about issues concerning DNSSEC validation itself.
The DURZ has been cautiously rolled out over the last few months and has been operational across all 13 root servers since May 5.
The original plan called for the roots to become validatable following a key signing ceremony on July 1
The schedule change from ICANN also comes with a notice that the US government will be asking for public comment before the decision is made to properly sign the root.
Prior to 2010-07-15 the U.S. Department of Commerce (DoC) will issue a public notice announcing the publication of the joint ICANN-VeriSign testing and evaluation report as well as the intent to proceed with the final stage of DNSSEC deployment. As part of this notice the DoC will include a public review and comment period prior to taking any action.
I may be just a little forgetful, but I can’t remember hearing about this Commerce involvement before.
Still, DNSSEC is a big change, so there’s nothing wrong with more of the softly-softly approach.
