Current status: We've monitored the environment and confirmed the service is restored. If you experience additional issues or have questions, please open a support case via Snowflake Community. Customer experience: Customers hosted in the specified regions may have been unable to access or use Snowflake services and features using Snowsight. Incident start time: 14:40 UTC September 24, 2025 Incident end time: 15:29 UTC September 24, 2025 Preliminary root cause: Connection failures between our service infrastructure impacted service availability. A root cause analysis (RCA) document will be published within five business days.

Current status: We've taken action to mitigate the impact and will continue to monitor the environment until we're confident all services are functioning properly. Customer experience: Customers hosted in the specified regions may have been unable to start, resume, or manage virtual warehouses. Virtual warehouses may have appeared as stuck in the associated state. Existing warehouses already running were unaffected. Incident start time: 10:46 UTC September 03, 2025 Incident end time: 11:21 UTC September 03, 2025 Preliminary root cause: A third-party cloud platform experienced a potential capacity issue which caused an inbility to start or resume virtual warehouses, resulting in the impact experienced by customers. A root cause analysis (RCA) document will be published within ten business days.

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. Customer experience: Customers hosted in the specified regions may be unable to access or use multiple core Snowflake services and features. Affected users may be unable to sign in, execute queries, or manage data. Incident start time: 00:30 UTC August 21, 2025 Incident end time: 01:16 UTC August 21, 2025 Preliminary root cause: Our initial investigation has identified an issue within our metadata database infrastructure. A root cause analysis (RCA) document will be published within seven business days.

Current status: During our investigation, our internal metrics indicated the service has self-recovered. We're monitoring to ensure the issue is resolved while we investigate its underlying cause. Customer experience: Customers hosted in the specified regions may have been unable to access or use multiple core Snowflake services and features. Affected users may have been unable to sign in, execute queries, or manage data. Incident start time: 20:47 UTC August 14, 2025 Incident end time: 20:57 UTC August 14, 2025 Preliminary root cause: We identified an issue that affected components that support the metadata management database within our cloud services layer, impacting customer connectivity and query operations. A root cause analysis (RCA) document will be published within seven business days.

Current status: We've monitored the environment and confirmed the service is restored. If you experience additional issues or have questions, please open a support case via Snowflake Community. Customer experience: Customers hosted in the specified regions may have been unable to execute queries, retrieve results, or manage data objects such as tables and views. Affected users may have seen "Processing aborted" errors. Incident start time: 18:14 UTC August 05, 2025 Incident end time: 20:11 UTC August 05, 2025 Preliminary root cause: A recent update caused a limited portion of service infrastructure that handles query jobs to encounter failures, preventing customers from executing queries as expected.
