If your AWS service is properly regionalized, that’s the minimum amount of cellular architecture required. Did your service ever fail in multiple regions simultaneously?

Cellular architecture within a region is the next level and is more difficult, but is achievable if you adhere to the same principles that prohibit inter-regional coupling:

You didn't really put any thought into what I said. Thanks for the links.

It wasn't worth thinking about. I'm not going to defend myself against arguments and absolute claims I didn't make. The key word here is mitigation, not perfection.

Amazon has had multi-region outages due to pushing bad configs, so it’s extremely difficult to believe whatever you are proposing solves that exact problem by relying on multi-regions.

Come to think of it, Cloudflare’s outage today is another good counterexample.
