IMO this is an example of why AWS is so valuable. Not only has Amazon designed their cloud to allow for redundancy (availability zones), but when something does fail they have smart people working on it immediately. Whenever I have doubts about using AWS in a project I always remind myself that the cost of the instance includes much more than the compute, storage, and bandwidth resources. It's all the other stuff as well: smart people watching over my bits, policies & procedures to ensure proper handling of failures, etc.
