make a hasty move to another region
I'm being horribly naive, but isn't one of the selling points of all this Cloudiness the ease, almost trivial ease, of creating/starting/stopping/migrating all these machines and their data?
Aren't you supposed to be able to pretty much select a location on a dropdown, click Ok and sit back whilst the Mighty Machinery Leaps to Your Bidding and seamlessly migrates the instances, finishing with a flourish by directing traffic to the new location?
And if any of that is true, at what point do SLAs indicate that Google should do that move automatically to work around issues in their own systems?
