## Updates from CircleCI

### postmortem, 2026-10-22 23:29 UTC

## Summary From 15:44 to 20:55 UTC on October 21, customers running Gen 2 Docker jobs saw increased wait times for their jobs to start. Delays were longest on the 2xlarge resource class, where jobs waited up to 20 minutes. The incident was caused by limited availability of the cloud instances we had configured to meet demand, particularly for 2xlarge jobs. In response, our engineering team configured additional instance types, configured additional Gen 2 Docker clusters. By 20:55 UTC, wait times had returned to normal and the incident was resolved. After the incident was resolved, we expanded our Gen 2 Docker fleet into additional cloud regions, and we continue actively standing up additional cloud regions to prevent similar incidents in the future.

### resolved, 2026-10-21 20:54 UTC

Wait times for gen2 Docker jobs have recovered and jobs are running within normal wait times.

### monitoring, 2026-10-21 20:40 UTC

We have seen a full recovery of wait times for docker jobs.

### identified, 2026-10-21 20:35 UTC

Wait times for 2xlarge docker jobs are now under 60 seconds. Wait times for other resource sizes were not impacted by this incident and remain under 10 seconds.

### identified, 2026-10-21 20:22 UTC

Wait times for 2xlarge docker jobs are recovering. We will continue to update as capacity comes online.

### identified, 2026-10-21 20:03 UTC

We are adding additional capacity to help mitigate the issue. Note: We are still seeing delays up to 20 minutes on 2xlarge.

### identified, 2026-10-21 19:31 UTC

Some users might see increased wait times for gen2 Docker jobs due to capacity issues.
