      Exactly this. If they didn’t do this, us-east-1a would be the biggest single point of failure the world has ever seen.

    Yeah. There is an api call that shows the mapping between a region's az names and the static az id's. I wasn't an early adopter but encountered the random az assignment in 2010.
