  I wonder why it took 3 hours to clear state. It didn't -- it took 3 hours to get all the machines talking again after the state was cleared. This is probably mostly due to two factors: 1. When doing a "clean restart" Amazon almost certainly had each S3 node look at the data it had stored to make sure that they had correct metadata; and 2. After each node had been restarted, Amazon probably had to relink them gradually rather than all at once -- most self-organizing network protocols have limits on the rate at which nodes can join or leave the network.

      Data integrity testing? This question no verb? Or rather... I have no clue what you're asking, can you clarify?

        "Data integrity testing was being performed?" I expect.

        The question mark isn't being used to end a question, he's using it to ask for confirmation of a statement. He's writing in a way that mimics how people talk to each when they meet face-to-face. For example: Jack: I wonder what Jill's favourite flavour of ice cream is. Sam: Chocolate? Jack: Yes, that's the one.
