CircleCI Status

Resolved: Mac M4 and M1 jobs are now running normally. Thank you again for your patience while we addressed this issue.

Investigating: We are investigating delays in M4 and M1 Mac jobs, and are working on resolving this as soon as possible. Thank you for your patience.

Resolved: This incident has been resolved.

Monitoring: This incident has been resolved. The CircleCI UI is not loading and operating normally for all customers. Thank you for your patience, and we apologize for any inconvenience this may have caused.

Monitoring: We have applied a fix which has brought the UI back online. We are monitoring for further issues.

Investigating: CircleCI UI is currently not loading. We are investigating, but jobs are running normally.

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

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.

Identified: 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.

Identified: 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.

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.

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.

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.

Identified: 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.

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.

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.
