Yes, but don't the root zone records expire just like other DNS records? Correct me if I'm wrong because I'd really like to be sure I'm understanding this correctly. I thought the records which are loaded into into the root level name servers are loaded directly from the registrar. So when I change may name servers with my registrar the change takes effect (at the root level) the next time the root records are loaded from the registrar. If the registrars server is down temporarily, no big deal, it keeps the old records until they expire and tries to load them the next time. But if the registrar is down for an extended period the records expire and then disappear. If there are no records pointing to my DNS servers they can't be found even if they are up and running. The root records have to expire at some point don't they? If not there would be records floating around for every domain that was ever registered directing traffic to old long deceased name servers.
