It sounds like they are using the update service to detect new sites. It is a theory of mine that Google's famous link based system has a major flaw in that many new websites don't have inbound links and don't develop them for a while. This may have forced Google to look at new (or relatively old) methods of site detection. It might be interesting to test it with a non-GD registrar. It is easier to handle the smaller zonefiles than it is to handle the .com zonefile (.com expands to about 6.5G of data) so they could have been using zonefiles and the domain registration time could have been near to one of the zonefile updates. A ccTLD registration test may help confirm if Google is using an update or zonefile service because most ccTLDs will not provide external zonefile access. This means that Google has to detect new ccTLD sites by crawling and if they pick up an unlinked ccTLD site as quickly, they could be using another method of detection.
