As part of our ongoing infrastructure improvements, we will be deprecating Mac M1 and M2 resource classes on February 16th, 2026.
Ahead of the deprecation date, we will be performing 24-hour brownouts from 00:00:01 to 23:59:59 UTC, during which these resources will be unavailable.
You can opt out of brownouts by disabling the setting in Organization Settings > Advanced > Enable image brownouts. However, please note that access to these resources will be entirely removed on February 16th, 2026, regardless of brownout settings.
Please plan to transition to M4 instances (m4pro.medium and m4pro.large) ahead of the deprecation date.
M4 resources will be made available to organizations on free plans starting November 10th, 2025. Posted on

Update -
During our maintenance, we identified an issue with the opt-out feature for the Mac M1/M2 brownouts. Organizations attempting to disable brownouts via Organization Settings > Advanced > Enable image brownouts may have found that the setting was non-functional.
A fix has been deployed and the opt-out feature should now be working as expected.

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.

Investigating -
We are currently investigating an issue affecting Usage API data availability for December 11, 2025. Customers querying usage data for this date will not receive results at this time. Usage data prior to December 11 remains accessible and unaffected.
This issue is isolated to data retrieval for the specified date. All other CircleCI functionality, including job execution and workflow triggering, continues to operate normally.
We are actively investigating the cause and will provide our next update within 30 minutes or as we know more.
