From T72901 (2001:4830:1600:391::2) and subnet, I can ping6 google.com (and many other places), but not 2604:8800:100:1aa::2 (a sixxs tunnel in Chicago).
From 2604:8800:100:1aa::2, they can ping6 google.com and many other places, but not 2001:4830:1659:911::81.

Never mind. Can ping6 2001:4830:1600:391::2 from 2604:8800:100:1aa::2, so it must be a local routing problem.

Actually, there may have really been a temporary problem, because it all works now (and I didn't touch anything).

Here is the traceroute6, now that it's working. Link between 2001:504:0:2:0:3:71:1 and 2001:504:0:2:0:2:2822:1 was apparently down - perhaps for maintenance?
