Incident Report
Hello,
We are currently investigating performance issues affecting VictoriaMetrics, which may result in degraded metrics ingestion and query performance.
Our team is working to implement performance optimizations to lower memory utilization across the write paths. These changes will be rolled out progressively across regions to minimize customer impact.
Expected Impact:
- Temporary degradation in metrics ingest and query latency.
- No data loss expected.
As the situation evolves, we will continue to provide our customers with updates on the matter. If you have any questions, we encourage you to reach out to support by email: support@coreweave.com
We apologize for any inconvenience this may cause and thank you for your patience while we work to resolve the matter in a timely manner.
Thank you,
