Update timeline

  1. identified Jun 17, 2026, 08:17 PM UTC

    We have identified an issue where alert rules and alerts managed directly in a Loki data source (data source-managed alerting) are not displayed in the Grafana Cloud Alerting UI. Rules created via Prometheus/Mimir data sources and Grafana-managed alert rules are not affected. Impact is limited to visibility and management in the UI. Affected alert rules continue to evaluate and send notifications normally — there is no impact to alert delivery. Workaround: Loki alert rules can still be viewed and managed directly through the Loki ruler API (for example, using cortextool against /loki/api/v1/rules). A fix has been identified and is in progress. We will provide a further update once it has been rolled out.

    Our Engineering Team has implemented a fix which is now being rolled out. We will continue to monitor the situation and update as soon as we have more information.

  3. identified Jun 17, 2026, 09:43 PM UTC

    Deployment of the fix is still in progress. We are continuing to monitor the rollout and validate recovery across affected systems. We will share further updates as they become available.
