AWS has lots of engineers in Seattle, but control plane is distributed. I'd personally expect a long delay in getting any fixes to things, but that many sites would be just fine.
I think you overestimate how resilient any of the cloud providers are to a massive gray failure. Lots of west coast infrastructure will flap. The survivors will have other priorities. I am going to revise my statement, I predict! a partial or nearly complete failure of the internet across multiple continents when this earthquake goes off.
But are all the buildings on the MS campus, for example, "built to code"? (that's the US phrase isn't it). Do we reasonably expect most, let's say, post-80s buildings to survive a magnitude 9+?
Most of the buildings that are more than a few stories tall on that campus are definitely build to modern-ish code. They’ve been slowing replacing the original stack with new office buildings.
