Never was a problem but I can't get here via IPv6.

Other sites are not an issue and I can get here on IPv4.

It still resolves but doesn't load anything.

I believe it should be fixed now. The server has been recently rebooted and the rc.conf's ipv6 configuration was broken so that the ipv6 network interface setup didn't succeed. I have fixed it and things seems to be working fine. Sorry for the inconvenience.

There seems to be a problem again with IPv6. Site takes forever to load. If I set firefox to IPv4 only it works as normal.

brd@ says it's working for him and I don't have ipv6 connectivity myself, so I can't verify here. Anyone else having problems?

Seems to work correctly now. The last two days however it didn't.

Yes, there were problems, both with the forums as with the main FreeBSD website, that lost its CSS around the same time.
That last problem still persists for me, but only with Konqueror, so it might not be related.

It appears IPv6 broke again.

It should be working now, the default inet6 route wasn't set up - I guess it is related to the recent HW upgrade; I will have to investigate.
Thanks for the report.

I doubt it's some local problem as the traceroute6(8) fails somewhere at the end.

Yeah, have the same problem since Tuesday. It fails at the same point, at ISC. Already tried contacting noc@isc.org but the last time I did that they claimed there was nothing wrong. Oddly enough, it started working again a few minutes after I received that reply.

You might want to try contacting them too.
