I've been having problems on and off reaching well-known IPv6 sites
from MIT; most notably, packages.debian.org. The problem always fixes
itself by the time I can get anyone to debug from the other end.
I think we have perhaps 3 separate problems at times:
* limekiller is occasionally down, but I think that's rare
* occaid sometimes totally flakes
* something much hairier about routes from packages.debian.org
If you would like to get mail from my nagios instance, please ask.
With debian, I think there is something wrong with routes in
oneandone.net. I think line 6 of the traceroute from linuxpal sould
match line 7 of the netbsd.org one.
Can you get a traceroute6 from debian to MIT?
