   monitoring
   Current status: We identified that a subset of infrastructure responsible for processing queries and Snowsight requests in the affected region experienced elevated load, which caused intermittent delays and query failures. The load has since subsided, and query processing and Snowsight performance have returned to normal. We'll continue to monitor the environment until we're confident all services are functioning properly. Customer experience: Customers hosted in the specified regions may have experienced intermittent delays when loading Snowsight or running queries, and some queries may have failed. Workaround: There were no available workarounds for this issue. Incident start time: 23:50 UTC October 15, 2026 Incident end time: 00:40 UTC October 16, 2026 Preliminary root cause: A routine software update caused a large number of background setup operations to run at the same time, which exhausted the resources of a subset of infrastructure responsible for processing queries in the affected region, resulting in intermittent delays and query failures.
