The server is having hard drive troubles yet again. I must say this is beginning to seem weird, seeing as how it's the third disk failing in less than a year. Either way, as usual, the server needs to be taken down again in order to replace the disk. I'll contact Hetzner shortly and update you on when it's going to happen. I'll also try to nag them about the cause of these frequent failures.
Update: Hetzner will replace the drive at 2012-08-08, 21:00 UTC, so I'll shut the server down a bit before that (which means, of course, that the website will be down as well). It might take a bit before it comes back, because they said they'll try to look into the frequent failures and debug it a bit.
Like last time (and the time before): since the game data is redundantly stored, there should be no danger to the world or any characters. However, I'll be having the game server itself shut down in the meantime just to be on the safe side. It is possible, though not yet certain, that minimap data will be lost.
