## Timeline of updates

- **resolved** 2023-06-21 17:30 UTC: Between 19:22 and 19:51, approximately 1.2% of messages failed, and a considerable number of our clients experienced re-connections. Our monitoring system experienced partial downtime, leading to confusion in our autoscaling policy. This confusion triggered a scale-down event in the cluster, resulting in reduced available capacity. Our engineering team has taken steps to prevent this from happening again. This incident has been resolved.
