Google no longer returning AAAA records?

[Brian Rak]

We noticed that we're no longer getting AAAA results back for google.com 
when we do queries from a few of our recursive servers (other ones are 
fine).

A bit of searching revealed that a few of our servers are listed here 
http://www.google.com/intl/en_ALL/ipv6/statistics/data/no_aaaa.txt 
(there are 4 listed for AS20473, which are the ones I'm referring to)

However, I can't seem to find any information about why we'd be listed 
there, nor can I find anything telling me how to get delisted.

I found an old mailing list post talking about contacting dns-admin@ and 
google-ipv6@, however dns-admin bounces telling me to go to 
google.com/support, and google-ipv6@ bounces with 'The group 
google-ipv6@ does not allow posting through email.'


Is anyone here that can help me, or tell me who I should be talking to?

Thanks,
Brian Rak
