It seems like if you're going to outsource your mission critical 
infrastructure to "cloud" you should probably pick at least 2 unrelated 
cloud providers and if at all possible, not outsource the systems that 
balance/direct traffic...and if you're really serious about it, have at 
least two of these setup at different facilities such that if the primary 
goes offline, the secondary takes over.  If a cloud provider fails, you 
redirect to another.
