AWS does not run “their control plane” out of us-east-1. Every single service has its own control plane independently hosted in its own region, with the exceptions of IAM, Route53, Cloudfront, and a small number of others like Global Accelerator.
IAM is usually the culprit when us-east-1 issues affect other regions, but Lambda runs independently in every region.
