My team didn't use STS but I know other teams at the company did. Those that did rely on non-us-east-1 endpoints did stay up IIRC. Our company barely use the AWS console at all and base most of our stuff around their APIs to hook into our deployment/CI processes. But I don't work at AWS so I don't know if it's true or if there was some other backend replication lag or anything else going on that was impacted by us-east-1 being down. We had some failures for some of our older services that were not properly sharded out, but most of our stuff failed over and continued to work as expected.
