At least according to the blog post, it seems like part of the issue may be a stampede of requests due to the complete outtage of a single AZ. If every single service hosted in the Amazon cloud did some sort of solution where they did failover to another Region in the case of multiple AZ outtages, how can we be sure that that stampede of requests wouldn't take out that other region? Could Amazon handle the entirety of the US East workload being dumped onto Europe/US West?
