The server is currently down, this appears to be due to malicious actions which have caused serious problems with a map chunk and are causing the server to be unstable.
I am working on resolving the problem now but may have to do a partial restore as well as removing the chunk, word data (excluding the chunk causing the issue) and player data (including inventories) should not be affected but it may take 20-30 minutes to get the server back online.
I'll update here as soon as possible, please bear with us!
UPDATE: 22:05 - This is going to take a while longer, progress is slower than I'd hoped, I'll post another update soon.
UPDATE: 22:15 - The chunk has been removed and the server is back up!
