Subject: IPv6 routing broken to one of bugs.debian.org's AAAAs
Date: Wed, 11 May 2011 23:01:32 -0400
Package: bugs.debian.org
Severity: serious
Tags: ipv6

bugs.debian.org's AAAA entries contains
2607:f8f0:610:4000:6564:a62:ce0c:1372, which is unreachable from
multiple locations on the internet. This breaks connectivity from
hosts that prefer ipv6; this AAAA record should be removed immediately.

I have tested from linode's newark datacenter, with the following mtr
trace:

bugs.debian.org's AAAA record is only 2001:858:2:2:214:22ff:fe11:ac9e,
which should work just fine. 2607:f8f0:610:4000:6564:a62:ce0c:1372
doesn't reverse to one of our machines.
