Builds failing in US West
We have identified an issue with our build infrastructure in US West that is causing some builds to fail before any build steps run. Affected builds fail with a "build daemon returned an error" message.
We are working on a fix. Running services are not affected. Users in other regions are not affected. If a build fails, redeploying may succeed in the meantime.
Note: This issue is unrelated to the security incident from October 21st. No action is needed on your part.

### 2026-10-28 10:36 UTC: monitoring
We have identified the cause of the build failures in US West and have applied a fix. Builds should be recovering now.
We are monitoring to confirm full recovery. Running services are not affected. If you continue to see build failures, retrying the deployment may succeed in the meantime.

### 2026-10-28 10:40 UTC: resolved
The issue causing builds to fail in US West has been resolved. Builds are now completing normally. If a build failed during this incident, redeploying it should now succeed. 
We apologize for any inconvenience. If you continue to experience issues, please contact support at https://station.railway.com.
