Current status: We've implemented the fix for this issue and monitored the environment to confirm that service was restored. 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 access or use multiple Snowflake services and features. Affected users may have been unable to sign in, use Snowsight, execute queries, resume virtual warehouses, or ingest files using Snowpipe or Snowpipe Streaming. Scheduled tasks and other automated workloads may also have failed to run or may not start as expected.

Impact start time: 17:50 UTC October 21, 2026
Impact end time: 21:25 UTC October 21, 2026

Preliminary root cause: A configuration change applied to the cloud services layer in the specified region interacted with existing settings in a way that caused a significant number of instances to be taken out of service. This led to cascading failures across sign-in, query execution, data ingestion, and other dependent services.

A root cause analysis (RCA) will be conducted and a summary will be made available within 5 business days.

Current status: Our monitoring indicates that the previously affected services have returned to normal operation. We'll continue to monitor the environment until we're confident all services are functioning properly.

This led to cascading failures across sign-in, query execution, data ingestion, and other dependent services.

Current status: Services in the specified region are recovering, and our monitoring indicates that most core services, including sign-in, Snowsight, query execution, and data ingestion, are returning to normal operation. We're continuing to monitor to confirm full recovery across all services. We'll provide another update within 30 minutes.

Impact start time: 18:00 UTC October 21, 2026

Preliminary root cause: A recent configuration change in the affected region caused service infrastructure to stop processing requests, resulting in a service disruption.

Current status: We're continuing to monitor the affected region, and we're seeing early signs of recovery. Affected services are recovering gradually, and we're working to confirm full restoration. We'll provide another update within 30 minutes.
