Exactomundo. Even Google has to accomodate such. That's why their model is piecemeal and localizes as much as they can.
But even Google has an ASN, AS15169, when it comes to their combined presence.
I think they know better than to try to flap BGP routing around to accomodate a failed computer at one site or another, though. Is that what you are suggesting?
BGP would normally be used to handle routing over multiple paths to a fixed location and would change in response to the route availability. You can play tricks by shuffling a route to a completely new destination if a whole site fails but the minimum you could move would be a whole class C at a time, and some bad things will happen during the switch as different machines with the old IP's become visible.
