One thing to keep in mind is that the DNS-LB used by Google/yahoo (in the examples above) seems to be returning a CNAME for AAAA queries, then nothing for the follow-up resolution request for a AAAA for the CNAME... So, ipv6 things may look 'broken' because they are also 'slow' (waiting to re-do much of the lookup path to get the A version)
