Incident Report

Summary AI Generated

Railway experienced a 10.4-hour incident where builds and deployments were significantly delayed due to a backlog in the build queue and an issue with builder storage. During the incident, builds and deployments for hobby plans were temporarily paused multiple times to reduce system load, while Pro plan services continued processing with delays. The incident was resolved by scaling up build workers, implementing tuning adjustments, and deploying a fix for the builder storage issue, allowing the queue to fully drain and normal processing to resume.

The build and deployment queue has fully drained and builds and deployments are processing normally for all plans. We've also identified and rolled out a fix for an issue with builder storage. We appreciate your patience throughout.

We are again temporarily pausing builds and deployments for hobby plans to better allow the system to recover. The queue has grown beyond a level where it can process effectively, and we need to reduce load before we can safely re-enable all plans. Pro plan builds and deployments continue to process. We are actively working on the issue and will provide further updates as the situation develops.

IDENTIFIED about 14 hours ago - at 05/20/2026 01:59PM

We are continuing to work through the backlog of queued builds and deployments resulting from yesterday's incident. To reduce pressure on the queue and help restore normal throughput, we are temporarily pausing new builds for free trial and hobby plans while we work through the remaining backlog. Builds on Pro and higher plans continue to process. We will resume builds for all plans as soon as the queue has stabilized.

We continue to work through an elevated backlog of queued builds and deployments. We have scaled up build workers and are rolling out tuning adjustments to increase throughput. This rollout is expected to complete within the next 30 minutes. The queue remains elevated but stable, and we are monitoring closely to confirm improvement.

MONITORING about 16 hours ago - at 05/20/2026 12:16PM

We have identified the root cause and deployed a fix. The build queue is clearing and new builds are starting to progress at expected times. Builds on free, trial, and hobby plans have been resumed. We are continuing to monitor the system to confirm stability.

INVESTIGATING about 17 hours ago - at 05/20/2026 11:21AM

We are seeing a backlog of queued builds, which is causing builds to take longer than usual to start and complete. To reduce the backlog, we are temporarily pausing new builds on the free, trial, and hobby plans.

Builds on Pro and higher plans will continue to process, though some delays may still occur.

Running services are not affected. We are actively working to clear the queue and will provide updates as the situation progresses.
