Summary

Investigating Issues with Data Source-Managed Alerting

We are currently investigating an issue affecting data source-managed alerting management functionality in Grafana Cloud. Customers may experience problems viewing, creating, updating, or managing alerts through Grafana when using data source-managed alerting. This issue is limited to alert management functionality within Grafana. Alert evaluation and backend alerting services continue to operate normally. Direct alerting APIs for Mimir and Loki remain fully operational and are unaffected. Grafana-managed alerting is not impacted. We identified this issue at approximately 20:45 UTC and are actively working on a resolution. We will provide additional updates as more information becomes available. Workaround: Customers can continue to use the direct Mimir and Loki alerting APIs while we work to restore normal functionality.
