That’s an entirely different type of problem, and avoidable by just using us-east-2 (I still don’t understand why people default to us-east-1 unless they require some highly specific services).
Is it that easily avoidable? A lot of AWS's control plane seems to have dependencies on us-east-1, or at least that's what it's looked like as a non-us-east-1 user during recent outages.
