Multiple facilities != "one datacenter"

  Like I asked below, do you have a citation?

    "No one data center serves two availability zones" : http://www.theregister.co.uk/2015/04/16/aws_data_centre_architecture_amazon_cto_werner_vogels/ http://www.theregister.co.uk/2015/04/16/aws_data_centre_arch...

      Is there a reason you're focused on AWS topics and your account is only ~2 days old? https://news.ycombinator.com/threads?id=DinkyG https://news.ycombinator.com/threads?id=DinkyG https://archive.is/fRf8i https://archive.is/fRf8i

        Given that they created the account to comment in the DynamoDB thread, I'd guess they're a DynamoDB developer, but that doesn't invalidate anything they've said in this thread -- they even provided a 3rd party source.

      From your link: "To solve latency, Amazon built Availability Zones on groups of tightly coupled data centres. Each data centre in a Zone is less than 25 microseconds away from its sibling and packs 102Tbps of networking." 25 microseconds at the speed of light (best case, through a vacuum; through fiber is significantly slower) is ~4.7 miles, and based on the quote, that is the furthest they are apart. If your buildings are within 1-2 miles of each other, they're essentially the same facility. That is not geographically redundant.

        Sure, it's not geographically redundant, but nobody in this thread claimed it was. DinkyG disputed that your "one datacenter" claim was false, which it appears to be.
