Incident History

Dec 16, 00:00 UTC
Completed - The scheduled maintenance has been completed.

Dec 15, 16:43 UTC
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.

Dec 15, 00:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.

Dec 11, 23:01 UTC
Scheduled - 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.
