How developers kept running during the AWS us-east-1 outage

This post details a specific failure mode encountered during the AWS us-east-1 outage where an auto-failover workflow for Temporal Namespaces in us-east-1 was blocked due to a dependency on the source region, prolonging recovery time for a small number of customers. It also highlights the successful operation of proactively failed-over namespaces and the overall resilience of the multi-region replication feature. The post outlines plans to fix the auto-failover workflow dependency and improve network partition detection for faster failovers.
