Preliminary root cause: Our preliminary investigation identified that the Snowsight application-hosting layer and the Snowsight-specific database layer experienced an issue that led to an unexpected surge in requests, leading to high resource utilization and preventing the service from processing the associated traffic, resulting in suspended login attempts.

A root cause analysis (RCA) document will be published within five business days.

Current status: We've completed a restart on systems related to the application layer. Our telemetry indicates that this issue is no longer occurring, and users should be able to successfully access the service via the Snowsight User Interface (UI). We'll continue to monitor the environment until we're confident all services are functioning properly.
