```diff
+ 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.
