Friendly reminder that for any given single availability zone, the SLA that AWS provides is one single nine. That means that they expect that availability zone to fail 10% of the time, or 6 minutes every hour. this very high failure rate comes up solutely for free, no need for a special region. Therefore, implementing a cross availability zone application that logs when packets are dropped should give you some idea of how your application handles failure.
