Resolved
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 regions may have experienced issues with AI and ML functionality. Specifically, when using Cortex Code in Snowsight, customers may have seen the following: “Internal Server error: You may need to start a new chat.” All other Snowflake features were not impacted.
Incident start time: 11:20 UTC August 18, 2026
Incident end time: 13:45 UTC August 18, 2026
Preliminary root cause: Resource exhaustion in the compute infrastructure caused container scheduling failures, resulting in AI and ML functionality becoming unavailable.
A root cause analysis (RCA) will be conducted and a summary will be shared on the Snowflake status page within 5 business days.
