Their main server had a major issue and their backup/recovery plan did not work (and probably had not been tested to work) so now they are scrambling trying to fix it?
If that's a major hosting provider I'd be looking for a move. There is no reason that a VPS (if that's what you are on) should be own for upwards of 24 hours. It should be as simple as migrating the VM instance to a new VPS server.
