I apologize, and there will be some form of credit being issued for this month's downtime. A user on the server running phpBB (not anyone here) has problems with their database being corrupted, which is causing mysql to cause a kernel panic (ie. total crash, or mysql crashing)
I'm in the process of moving that site to a dedicated server at this time. Hopefully that will be completed this evening. We had 3 people working on this server all night last night and this morning running diagnostics and stress tests to find out what the exact problem was, and that one account does seem to be the problem.
Once that account gets moved and I can test to ensure the problems do not return, I'll have an update for everyone located on this server.
