Before: not present
After: 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. 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: 18:00 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.
