Indeed Ian, makes no sense if they were without a physically remote hot backup data center with fully redundant data, available to switch on promptly should the main site be lost.
I wonder if their are or will be regs about that kind of thing.
Speaking of regs, what about EC 261, that automatic-compensation for delayed/cancelled flights in EU? I've used it myself a few hrs back.
Lot of folks stranded in LHR or Amsterdam might want to make use of it! I wonder how many Yanks know about it though...
