Higher wait times for Linux, Remote Docker and ARM resource classes

Incident Report for CircleCI

Resolved

Between 21:14 and 21:26 UTC, December 15, 2025, customers using Machine, Linux Remote Docker, and ARM resource classes experienced elevated wait times when starting jobs. Wait times reached up to 5 minutes during this period due to the delays in our infrastructure scaling to meet the demand.

The issue has been resolved and wait times have returned to normal levels. Jobs are now starting within expected timeframes. No further action is required from customers, and no jobs were lost during this incident. Thank you for your patience during this brief disruption.
