This incident also had impact on Frontend Observability for the same region.
A fix has been deployed, and things have stablized. We will continue to monitor on our end.
identified
We’ve identified the cause of an issue impacting Log writes. Our team is currently implementing a fix.
Some Grafana UI features may be unavailable or reverting to legacy behaviour
A fix has been applied and metrics write error rates in prod-us-central-0 have returned to normal levels. Metrics ingestion is operating as expected. We are continuing to monitor the affected systems to confirm full recovery before marking this incident resolved.
investigating
We are investigating elevated error rates affecting metrics writes in prod-us-central-0. Customers in this region may see failed or delayed metrics ingestion, gaps in recent data on dashboards and queries, and alert rules that depend on the affected series may not evaluate as expected.

monitoring
We are rolling out a mitigation across the environments in these regions, and preemptively where possible to ensure it doesn’t spread elsewhere.
monitoring
We have seen an increase in latency in our cloud providers services, and are rolling out a change to mitigate the issue. We are monitoring.
monitoring
We are continuing to investigate this issue alongside the CSP, and have taken steps to escalate through the appropriate channels. The mitigation in place continues to work as expected, and any notable updates will continue to be shared here for tracking.

monitoring
We've implemented mitigation in place and are continuing to monitoring and investigating this issue.
investigating
We have begun rolling out mitigation steps to reduce write latency in the prod-us-central-0 and prod-us-central-5 regions. While these measures are expected to improve performance, we are continuing to investigate the underlying root cause of the issue. We will provide additional updates as more information becomes available.
investigating
Since February 19, we have been investigating an intermittent issue causing increased write latency in the prod-us-central-0 and prod-us-central-5 regions. The issue does not affect all traffic but may result in delayed write operations for some customers. Our engineering team is actively working to identify the root cause and stabilize performance. We will share additional updates as progress is made.
