Recent history

2 August 2026

Elevated query latency, eu-central. A downsampling worker held a compaction lock longer than expected after a node replacement. Queries over ranges beyond 30 days returned slowly for 41 minutes. Lock timeout has been shortened and alerting added on lock age.

17 July 2026

Scheduled maintenance completed. Storage nodes in eu-north were moved to the new block format. No ingest interruption; query results were served from replicas throughout.

28 June 2026

Delayed notifications. An upstream email provider queued messages for roughly 12 minutes. Webhook and pager delivery were unaffected.
