Incident Report

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 2 days ago - at 11/18/2025 07:57PM

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 2 days ago - at 11/18/2025 07:10PM

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.

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.

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.
