us-west-1 only has two availability zones available to new customers (they have three total, but one of them only runs legacy customers). From my experience it is also slower to get new hardware and services.

My personal belief is that running the "region" is far more expensive than running their other regions. Real estate in the bay area is expensive, as is electricity.

Good to know. The plant asset costs must merely be staggering instead of eye-bleeding. ;)

Unlikely it’s just San Jose unless there’s only one AZ (and there’s two, plus one for legacy customers only I thought). Each AZ is customarily separated by at least a distance of a few miles.
