A friend of mine who works at WF told me they lost an entire datacenter to a fire. I can't find any 3rd party evidence to back that up, but I have no reason to not believe my friend.

I guess their catastrophic recovery plan didn't survive a real incident.

edit I guess fire suppression systems were activated in a datacenter and some series of events knocked the entire building offline and automated DR failed. So if that's true, at least the risk of data loss is probably less than if the entire thing burned down.
