On October 23rd the data center where our server is located had a power failure. The server was rebooted and at the first look everything was fine.
In the morning we noticed that the performance was bad and started to investigate and found out that one of the hard disks was failing.
The drive has been replaced and is now synchronizing.
Update: A few hours after the server was back online, MySQL found out that the bbs db had been corrupted. We have restored a backup from Mon Oct 24 09:47:59 CEST 2011. Unfortunately all forum posts made after this date have been lost.
We are sorry for the long downtime.
