Just for the record; your issue is slightly different:

You wrote:

"deb.debian.org is a CNAME for debian.map.fastly.net. There are no AAAA 
records for fastly.net so any DNS querys from an IPv6 only resolver will 
not work."

At the moment debian.map.fastly.net has an AAAA-record though.

The thing is; the authoritative name servers of fastly.net are only 
willing to hand out that AAAA-record via IPv4. So it still doesn't work 
with the (locally installed) IPv6-only resolver ;-)

Cheers,
