   Current status: We've 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 core Snowflake services and features, including signing in to Snowsight, executing queries, loading and unloading data, and using Snowpark Container Services. Some customers may have also experienced delays with Snowpipe Streaming ingestion and elevated error rates when accessing Snowsight. The majority of impact was resolved at 17:25 UTC; however, some customers may have continued to experience some residual errors or increased latency until approximately 18:10 UTC. Incident start time: 16:58 UTC August 31, 2026 Incident end time: 18:10 UTC August 31, 2026 Preliminary root cause: A recent configuration change degraded backend processing due to a compatibility issue with how the affected systems handled requests. As a result, the infrastructure experienced resource contention and subsequent impact to multiple Snowflake services and features. A root cause analysis (RCA) will be conducted and a summary will be shared on the Snowflake status page within 5 business days.
