The site has been (semi) offline for a couple of days now. I took the database server that drives the site down because I’m virtualizing a lot of my infrastructure. Because it took longer than I thought it would to get everything back online, only cached pages were being served. The cache eventually times out and requires regeneration from the database, which it couldn’t do, and returned error 500 pages! Anyway, the new (virtualized) database server is up, so the site is back online
