The server pulled its usual crashing trick some hours ago, and came back up after rebooting but without the database partition mounted or the mailing lists activated.
Everything should be fine now, for a definition of "fine" that means "could crash again at any time and going to have to handle the full English webserving load as well as the database and all other languages until we get both servers fixed".
