He went down? Now, what exactly are you suggesting, OP?
That's quite strange. How long was it down for? It was just the forums, I tried www.qhimm.com and it worked.
What was the reason for this?
Few hours - about four. After a particularly heavy load, the host developed issues with the database server, which went down and damaged the database while doing it. Then it was mostly the matter of waiting for the Master to wake up.
Main page does not pull anything from a database AFAIK, and while the wiki probably does, it apparently behaves better in case of a database server crashing, or just wasn't under as much of a load as the forum database was.
