us-east-2 goes down far, far less frequently than us-east-1. AWS doesn’t publicly release the outage numbers (they hold them very close to the chest) but some people have compiled the stats on their own if you poke around.

The regions provide the same functionality, so I see genuinely no downside or additional work to picking the 2 regions over the 2 regions.

It seems like one of those no brainer decisions to me. I take pride in being up when everyone else is down. 5 9s or bust, baby!
