Resolved - Between 20:20 and 20:26 UTC, following our scheduled RabbitMQ maintenance, a small number of workflows may have experienced issues with GitHub check notifications.

Impact:
- Some workflows showed no check run status in GitHub
- Some workflows showed check runs stuck in "pending" state
- User flows requiring these checks may have been blocked

Resolution: This issue resolved upon completion of our maintenance. All services are now operating normally.

We apologize for any inconvenience during this maintenance period. If you have builds that completed during this window with pending or missing checks, a rerun will restore the correct status.

Nov 22, 01:00 UTC
Nov 21, 2025
Completed - The scheduled maintenance has been completed.
Nov 21, 22:00 UTC
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Nov 21, 20:00 UTC
Scheduled - We will be performing scheduled maintenance on our message queue infrastructure to improve system reliability and performance on Friday November 21, 2025 from 20:00 to 22:00 UTC.

During this maintenance window:
- Brief delays (up to a minute) may occur when starting new jobs
- Job processing may also experience minimal delays during the maintenance period
- All running jobs will continue without interruption

What remains fully available:
- CircleCI UI and API
- All existing configurations and settings
- Job execution (with above mentioned delays)

Our engineering team will be actively monitoring throughout the maintenance window. Thank you for your patience as we work to improve CircleCI's infrastructure.

Nov 18, 2025
Resolved - This incident has been resolved. All resource classes including Linux, ARM, AMD, and Remote Docker are operating normally with standard queue times. System performance has been stable and capacity has been restored.

Thank you for your patience while our engineers addressed this issue

Nov 18, 19:57 UTC
Monitoring - Task wait times have returned to normal for all resource classes including Linux, ARM, AMD, and Remote Docker. We are monitoring system stability before marking this incident as fully resolved.

Current Status:
- All resource classes: Operating with normal queue times
- System performance: Stable and meeting expected levels
- Monitoring: Actively watching for any signs of recurring capacity constraints

We will continue monitoring for the next 30 minutes to ensure the improvements are sustained before closing this incident.

Thank you for your patience during this disruption. Next Update: Within 30 minutes or when resolved.

Nov 18, 19:10 UTC
Update - We're seeing improvements in job start times for Linux, ARM, AMD, and Remote Docker resource classes. We are actively working on a stable solution to address this issue.

Current Status:
- Linux, ARM, AMD and Remote Docker jobs: Wait times have improved, though some delays may still occur
- Docker, Mac, Windows, and Android jobs: Operating normally

Our engineering team continues to work on implementing additional capacity and solutions to prevent future constraints. While current performance has improved, we're keeping this open as we work toward a stable resolution.

Thank you for your patience as we address the underlying capacity challenges. Next Update: Within 30 minutes or as conditions change.

Nov 18, 18:09 UTC
Update - We continue to work on addressing the capacity constraints affecting Linux, ARM, AMD, and Remote Docker resource classes. Job start delays remain stable at approximately 3 minutes.

Current Status:
- Linux, ARM, AMD and Remote Docker jobs: Delays holding steady at up to 3 minutes
- Docker, Mac, Windows, and Android jobs: Operating normally without delays

Our team is actively pursuing multiple approaches to expand capacity and reduce these delays. All jobs continue to run successfully after the initial wait time.

Thank you for your continued patience as we work toward resolution. Next Update: Within 30 minutes or when conditions change.

Nov 18, 17:19 UTC
Identified - We are currently experiencing capacity constraints affecting Linux, AMD, ARM and Remote Docker resource classes, resulting in job start delays of up to 3 minutes.

Current Status:
- Linux, AMD, ARM and Remote Docker jobs: Experiencing delays up to 3 minutes due to capacity constraints
- Docker, Mac, Windows, and Android jobs: Operating normally without delays

Our engineering team is actively working to address these constraints and expand available capacity. All jobs will continue to run normally after the initial delay.

We appreciate your patience as we work to resolve this issue. Next Update: Within 30 minutes or as the situation changes.

Nov 18, 16:44 UTC
Nov 17, 2025
Resolved - This incident has been resolved. All resource classes including Linux, AMD, and Remote Docker are now operating normally with standard queue times. The additional capacity has been successfully deployed and job start delays have been eliminated.
Thank you for your patience while our engineers worked through this issue.

Nov 17, 20:23 UTC
Monitoring - We continue to see reductions in average wait times for customers requesting Linux, AMD, and Remote Docker resource classes, with maximum delays now reduced to under 3 minutes.

Current Status:
- Linux, AMD and Remote Docker jobs: Wait times continue to improve, maximum delays of just under 3 minutes
- Docker, Mac, Windows, and Android jobs: Operating normally without delays

Additional capacity continues to come online, and we expect further improvements as our infrastructure scales to meet demand.

Thank you for your patience as we work toward full resolution.
Next Update: Within 30 minutes or when normal operation is restored.

Nov 17, 19:51 UTC
Update - We are actively adding additional capacity to reduce job start delays for Linux , AMD and Remote Docker resource classes. Current improvements show average wait times are now under one minute for most jobs, with some customers waiting up to 6 minutes for jobs using these resources.
.
Current Status:
- Linux, AMD and Remote Docker jobs: Wait times improving as we expand capacity, delays up to 6 minutes
- Docker, Mac, Windows, and Android jobs: Operating normally without delays

Our team is continuing to deploy additional resources to fully eliminate the remaining delays. We expect continued improvement over the next hour as this expanded capacity comes online.

We appreciate your patience as we optimize our infrastructure to meet current demand.
Next Update: Within 30 minutes or when normal operation is restored.

Nov 17, 18:46 UTC
Identified - We have identified the cause of Machine and Remote Docker delays. We are making changes which we expect to reduce the delays. All jobs will continue to run normally after the delay, and we expect the delay will decrease with time. Thank you for your patience.
Nov 17, 17:00 UTC
Investigating - We are investigating Machine and Remote Docker delays. We are working on resolving this as quickly as possible. All jobs will continue to run normally after the delay. Thank you for your patience.

Resolved - We have identified and applied a workaround for the RAM DIsk issue, which means customers can resume builds using `/mnt/ramdisk`. We appreciate your patience and understanding whilst we worked on resolving this whilst ensuring the security of our platform for all customers.
Nov 10, 11:24 UTC
Monitoring - At present customers running Docker containers cannot use /mnt/ramdisk. Customers will need to modify their configuration to use the filesystem instead.

This has occurred in order to update the Docker Infrastructure that supports our `working_directory: /mnt/ramdisk` feature. This is a necessary step in order to address CVE-2025-31133, CVE-2025-52565, and CVE-2025-52881.

This bug affects any Docker jobs utilizing `working_directory: /mnt/ramdisk`. Jobs will fail on checkout and workspace attachments.

The immediate workaround will be to remove any usage of `working_directory: /mnt/ramdisk` from your job which will require an update of `.circleci/config.yml`

Once this maintenance is complete, customers will be unable to utilize `working_directory: /mnt/ramdisk`until further notice.
