Gna! server did not survive a reboot while upgrading its main OS. It should be fixed and replaced by new hardware if needed by Friday 10 feb.
Sorry for the inconvenience.

I think this Gna.org system administrator puts it better than anyone else ever could.
From what I read on their IRC channel, an upgrade from Debian lenny (oldstable) to squeeze (stable) went wrong while there was nobody around with physical access to the host to fix the problem and make it boot again. Why one would perform an operating system upgrade in such circumstances is beyond me, but I can certainly say the Wesnoth bug and patch trackers, and the Subversion repository won’t be available until that’s fixed.
I for one am glad to use git-svn.
UPDATE (2012-02-11): According to the admins, the machine didn’t power on again after the upgrade, so it’s not just a software issue. Any needed repairs will have to wait until Tuesday, February 14th.
