I'd say the answer depends on how fast GAE recovers. If you're building redundancy over multiple clouds, if there's a lot of data:
1) It's very complex and expensive
2) You're looking at DNS to hot failover, in most cases.
If GAE can recover in less than 30 minutes and sticks to, say, one outage a year, you just can't justify the kind of cost you're looking at with 2 (seriously, it's a lot of cash).
