I honestly don't get the fascination with the death of Osama. Who cares? It's not like his death magically undoes 9/11. 9/11 sadly still happened, whether Osama is dead or not. Also, Osama is just one of thousands in his organization. He was already irrelevant.
What few people seem to acknowledge is that the post-mortem doesn't matter. It may or may not help Amazon, because the next outage (which will occur, as it does in any data center) will likely have completely different causes than this one. The post-mortem does not help the consumer in the least. Whether the cause of the outage was the long series of complicated steps explained in the post-mortem, or whether it was due to Engineer X accidentally tripping over a cable, the effect is the same. The publication of the post-mortem is simply meaningless. It would make much more sense for them to publish details of their entire architecture and infrastructure.
Sorry, this is not news.
