You left out the authority section that refers you to the correct DNS
darned it :( yes.
servers - ns[1-6].hp.com are not it. They delegate to another set of HP servers, which all time out (as stated by the OP) when asked for AAAA.
yup :(
Oddly, it seems to be specific to AAAA; any other type request I send comes back NOERROR correctly. It is like somebody tried to handle AAAA "special" and screwed it up.
I remember nytimes doing something like this for a while, I believe they said their GSLB was just not happy doing AAAA, or if not configured would display similar behaviour. -chris
