Cloud Storage latency in GCP us-central1 has returned to normal levels. We are continuing to monitor the region and will begin failing multi-region namespaces back to us-central1 shortly.

### investigating, 2026-10-08 21:53 UTC

We are monitoring elevated Cloud Storage latency from GCP in us-central1. As a precaution, multi-region namespaces in this region have been failed over to their replica regions. No impact to workflow execution has been observed. We will fail back once GCP confirms recovery.
