Like Mark described, for us too they dropped the goofy dual-session =
thing for IPv4 so we just have an IPv4 and an IPv6 session now.

Yeah, there's that ... (We have a couple other providers, too, so we =
don't really care but it's goofy).
Worse, for us, is that their router doesn't respond to neighbor =
discovery requests, so I had to make a static neighbor entry on our =
router for the session to come up. Not very pretty. I spent more than =
an hour on the phone with them and they didn't have any ideas (we have =
plenty other IPv6 sessions for transit and peering on the same router =
that are working fine).
Somewhere on the internets someone anecdotally told they had a Cisco =
router that did the same thing until it was rebooted. Didn't bother =
calling them to tell them to reboot the router we are on. :-)
Anyway, I guess the lesson is that they (like most providers, I am sure) =
don't have that much IPv6 experience and they didn't care that much that =
it didn't work right. Hopefully that attitude will change over the next =
months.
