   Incident End: 16 September 2026 07:51
   Duration: 0 hours, 47 minutes
   
   Summary
   On Wednesday, 16 September 2026, Google Workspace (specifically Google Drive) experienced an issue where a subset of traffic was dropped for a duration of 48 minutes.
   
   Preliminary Root Cause
   This incident was triggered by a planned capacity test, which temporarily reduced Google Drive's serving capacity.
   The sequence of events leading to the impact was as follows:
   Engineers initiated a routine capacity test, causing Drive to operate with reduced capacity.
   The remaining available capacity was insufficient to handle peak user traffic.
   As traffic exceeded capacity, the capacity protection system was triggered and began blocking legitimate Drive requests.
   
   Remediation
   The issue was detected on Wednesday 16 September 2026 at 7:03 via automated outage detectors monitoring error rates and user queries.
   To mitigate the symptoms, Google engineers initiated an immediate rollback of the capacity test to restore serving capacity. Additionally, engineers performed manual upsizing operations to provide mor

   Incident Report
   Summary
   On Wednesday, 16 September 2026, Google Drive experienced an issue where a subset of traffic was dropped for a duration of 39 minutes.
   We sincerely apologize for the disruption this incident caused to your business. We recognize the critical role Google Cloud plays in your operations and deeply regret the impact on your services. Our engineering teams have resolved the issue and have taken immediate measures to address the incident. Additionally, engineering teams are conducting a comprehensive review of the incident to fully address the root cause and prevent the recurrence of such an event.
   
   Root Cause
   This incident was triggered by a planned capacity test which temporarily reduced Google Drive's serving capacity.
   The sequence of events leading to the impact was as follows:
   Engineers initiated a routine capacity test, causing Drive to operate with reduced capacity.
   The remaining available capacity was insufficient to handle peak user traffic.
   As traffic exceeded capacity, the capacity protection system was triggered and began blocking legitimate Drive requests.
   
   Remediation and Prevention
   The issue was detected on Wednesday 16 September 2026 at 7:03 via our automated outage detector systems that monitor error rates and user queries.
   To mitigate the symptoms, Google engineers initiated an immediate rollback of the capacity test to restore serving capacity. Additionally, engineers upsized available capacity and updated the system load limit threshold to add more capacity headroom.
   
   Google is committed to preventing a repeat of this issue in the future and is completing the following immediate actions:
   
   Resilience and Resourcing: Ensure sufficient buffer capacity is available globally during capacity tests.
   Address the Root Cause: Engineering is conducting a comprehensive review of capacity modeling and protection thresholds to en
