Anyone know how this could affect multiple zones? "Customers can failover to zones in other regions". Unless a whole area got flooded.

There's an interesting Twitter thread about that topic here: https://twitter.com/GergelyOrosz/status/1651256082424012806 Based on that thread it sounds like only AWS guarantees that their AZs are in physically separate DCs, while for Google and Microsoft AZs could be in separate buildings of the same DC facility.

AWS treats its availability zones very seriously, each zone has its own independent power substation, air conditioning, and fiber lines. It's incredibly rare for multiple AZs to go down at once, especially since they are more than a few miles apart from each other.
