It's a bit of a bummer when mysql is down. 80% of my sites MUST have it.
Umm more than the specific PHP errors, showing the QUERY for BILLING is a bit of a no-no.I don't think I've built a site in the past 5 years without it.
I'd be more concerned with the host displaying errors & db information than I would be sweating the downtime. I'd like to think my host is production ready to the point that it can gracefully handle this stuff behind the scene.
