In previous projects I have worked on many years ago, the "down for maintenance" page was the page that was automatically served by the reverse proxy whenever we took the backend app servers down for whatever reason (emergencies, planned releases etc) Granted this was years ago - I don't know what people do these days if all backend servers are unavailable. I guess the alternative to "planned maintenance" is the more-accurate message of "OMG - shit's on fire dude!" but that is not appropriate for corporate PR speak ;-) Sounds to me like someone probably got a "turn everything off while the police investigate - do not touch anything or we'll chop your fingers off/fire you" edict from management, so they wont even put up an unplanned-emergency message for fear of crossing-management/damaging evidence/screwing up while putting up a rushed message/letting hackers back in/etc
