## Timeline of updates

- **investigating** 2026-09-02 16:02 UTC: We are observing OTEL ingestion backlog in US region
- **identified** 2026-09-02 16:24 UTC: A deployment rollout coincided with a traffic spike, resulting in an unusually large backlog. Adjusting our autoscaling to absorb the backlog faster.
- **monitoring** 2026-09-02 16:49 UTC: Backlog is almost completely gone. Ingestion delay is \< 1 min.
- **resolved** 2026-09-02 16:56 UTC: Completely back to normal
