Guys you don't have to worry. We have disabled the twitter account some time ago (after the design refresh when we removed the social sidebar..) because we used it only for posting new items and this was at the end only spam, no real content.
We had an issue with our hard disk , therefore our raid system needs to be rebuilt and we need to run FSCK command to repair the file system. This will take some time and I hope we can get back in max 24 hours.
All funds are safe + we have backups for all files. I am sorry for the circumstances this unexpected maintenance is causing.
