On October 20, 2025, a major outage occurred when Amazon Web Services' us-east-1 region went offline, affecting numerous businesses and applications globally. Temporal, a company specializing in durable execution platforms, managed to maintain workflow continuity during the outage due to its multi-region and multi-cloud replication capabilities. Temporal Cloud detected the issue before it was officially reported and ensured that customer workflows continued to operate by allowing users to trigger failovers to alternate regions. FireHydrant, a customer of Temporal, successfully utilized these features to maintain service during the incident. Although the company faced some challenges, such as a dependency on the affected region that delayed auto-failovers, proactive measures by Temporal's engineers ensured that most customer Namespaces resumed operations in alternate regions. The company plans to address these issues to improve response times in future incidents and reinforce its commitment to providing robust and resilient services for developers.
