Grafana Cloud experienced a major incident affecting its US Central region. The outage impacted query performance and metric rule evaluations, though metric ingestion continued uninterrupted.
Grafana Cloud provides cloud-hosted monitoring and observability infrastructure used by organizations to track application and infrastructure performance.
From approximately 20:24 UTC to 20:47 UTC, a network issue in the prod-us-central-0 availability zone isolated a portion of backend services, causing elevated query latency and delayed metric evaluations. Some write-path errors occurred in the logging subsystem. Customers may have experienced failed queries or rule evaluations during the window.
All systems recovered automatically once network connectivity was restored. The incident is now fully resolved.
