99.999999999% uptime?

  ... which translates to 3ms of downtime in 10 years with their current data, which makes no sense. I'm guessing it's closer to the way that telecom guys work: 1 bit error in 10^12 bits is common for fiber comm.

    Their explanation is here: http://aws.amazon.com/s3/#protecting http://aws.amazon.com/s3/#protecting Looks like they're differentiating between durability ("99.999999999%") and availability ("99.99%"). So it's not uptime that has 11 9s…my mistake. Should have checked the documentation.
