ISI-LAP doesn't nicely connect to you but are announcing it...

btw... QWEST-IPV6 has an unstability rating of 57.6% here... which is
quite high imho, nothing bad but not quite nice either ;)
btw2: check the list at
http://dmoz.org/Computers/Internet/Protocols/IP/IPng/IPv6_Route_Views/
to check where it could go wrong.
btw3: Nice to see ep.net going v6 when are the servers following ? :)

Greets,
