Are you positive someone doesnt have FTP access?
Your site was weirded out when I viewed it...
first it shows active...
then it shows database error...
now its a redirect to Google...

You should get someone in there that can track and resolve the issue.
One thing I have done before to a forum is create a custom 'database error' page
which is a type of landing page for isolated banned members and IP's
That way, a certain group believes the forum to be down when its really not.
To make it work properly, you need to resolve proxies to true IP though.

If youre having difficulties, I advise shutting down the entire site until you can locate
the source of the problem.
Better to be offline for awhile than having your members deal with site and member problems.
