The October 8, 2026 Google Cloud Storage Outage
Introduction
Google Cloud Storage in us-central1 (Iowa) had elevated latency and error rates on upload and write operations on October 8, 2026, and a smaller subset of reads was also affected, according to Google's incident page. Google records the start at 11:00 UTC and the end at 23:30 UTC the same day - 12 hours 30 minutes. The outage report - fetched on October 12, 2026 - includes a preliminary incident report as of this writing. Google attributes the impact to a traffic sorting optimization that caused severe resource exhaustion on specific backend storage nodes in us-central1, and to a separate issue in the underlying database service that added metadata processing errors for part of the window. Google says the report is preliminary and a full root cause analysis is still underway.
