    I think people are overthinking this. I'm the first one to criticize AWS (I run a competitor, carolinacloud.io) but I don't think we should hold it against them when they lost data due to their hard drives being physically bombed.

      Of course not.

      The surprising thing is that multiple availability zones were bombed simultaneously.

      And to my knowledge, they haven’t even yet said 2+ AZs were compromised.

        Turns out that "availability zones" in cloud parlance seem to have nothing to do with geographical availability. Apparently they're logical splits and are more about billing than anything.

          > An Availability Zone is one or more discrete data centers with separate and redundant power infrastructure, networking, and connectivity in an AWS Region. Availability Zones in a Region are meaningfully distant from each other, up to 60 miles (~100 km) to prevent correlated failures, but close enough to use synchronous replication with single-digit millisecond latency.

          They are far enough apart that tornados, floods, and fires cannot simultaneously impact multiple.

            Elsewhere in this threat comments mention AZ turning out in practice to be different areas of the same building, or just a matter of opinion and some config.

              Yeah that’s true of Azure and of GCP but not AWS. Azure clearly states this in their documentation. Nobody was trying to hide it from you.
