## Updates from Temporal Cloud

### resolved, 2026-10-10 00:51 UTC

This incident has been resolved. The AWS us-east-1 region is stable and all affected namespaces have been failed back.

### monitoring, 2026-10-09 23:11 UTC

Latency and error rates in AWS us-east-1 have returned to normal levels and affected namespaces have recovered. We are continuing to monitor the region. We will provide another update once failback is complete.

### investigating, 2026-10-09 22:50 UTC

Mitigation remains in progress. We are continuing to fail over affected namespaces with Multi-Region Replication enabled to their replica regions. Some customers may continue to experience elevated latency while this work is underway. We will provide another update within 30 minutes.

### investigating, 2026-10-09 22:38 UTC

We have identified the cause of elevated latency affecting a subset of namespaces in AWS us-east-1. Namespaces with Multi-Region Replication enabled are being failed over to their replica region to restore service. We will provide another update within 30 minutes.

### investigating, 2026-10-09 22:33 UTC

We are investigating elevated latency and increased deadline exceeded errors affecting some namespaces in the AWS us-east-1 region. Workflows may progress more slowly than usual. Our team is actively working to identify the cause. We will provide another update within 30 minutes.
