Could someone from Google contact me off list to discuss the public resolvers? I'm getting NXDOMAIN and then a proper response literally one second later. And from there it's just 20 GOTO 10...the resolver seems to be having a psychotic episode, or...at the very least...an identity crisis.
These symptoms have been seen on DNSSEC validating resolvers when they encounter a signed zone that is misconfigured. Google has recently begun DNSSEC validation, so it could very well be related, depending the configuration of the zone in question, including whether or not it is signed, and Google's resolver/validator implementation.
