Incident
Report for Snowflake
Resolved
Current status: We've confirmed that this issue has been resolved, and we have monitored the environment to confirm that the affected functionality is now working as expected. If you experience additional issues or have questions, please open a support case via Snowflake Community or the Support page in Snowsight.
Customer experience: Customers hosted in the specified region may have been unable to start, resume, or manage virtual warehouses. The impact occurred during the periods of 13:33 to 15:20 UTC, and 16:05 to 16:36 UTC on August 03, 2026. Virtual warehouses may have appeared as stuck in the associated state. Existing warehouses that were already running may have been unaffected. Customers may also have seen queued or delayed queries for workloads running on affected warehouses. Additionally, some serverless tasks may have experienced residual queuing or failures until the backlog of requests which accumulated during the impact windows was processed.
Incident start time: 13:33 UTC August 03, 2026
Incident end time: 16:36 UTC August 03, 2026
Preliminary root cause: A Cloud Services component responsible for virtual warehouse management became unhealthy. This caused failures in the internal workflows used to allocate and manage compute resources for warehouse start and resume operations, resulting in customer impact.
A root cause analysis (RCA) will be conducted and a summary will be shared on the Snowflake status page within 5 business days.

Monitoring
Current status: We have identified that the previously affected Cloud Services component became unhealthy again, which is preventing virtual warehouses from starting or resuming. We've implemented an additional fix and we're continuing to monitor to confirm that we have fully recovered. We'll provide another update within 60 minutes.
