It’s interesting that multi-region is often touted as a mechanism for resilience and availability, but for the most part, large cloud providers seem hopelessly intertwined across regions during outages like these.

This is really only a problem on GCP, who treats regions far differently from other providers.

From a resilience perspective, it's best to treat GCP as a single region with a bunch of zones.

Mind the unknown unknowns there. You are not aware of all the "outages like these" that could have occurred but did not thanks to regional/zonal sharding.

I dont think you can really make a conclusion without first understanding occasions where multi-region deployments have prevented incidents.
