### 2026-04-10 21:56 UTC: postmortem
### \*\*Dates:\*\*
Monday April 7th 2026, ~11:00 – 15:55 UTC
### \*\*What happened:\*\*
Some customers experienced 503 errors when running tests via saucectl. The test-composer service was intermittently unavailable, preventing framework-based test execution.
### \*\*Why it happened:\*\*
A stale Docker image was deployed to the test-composer service due to a packaging issue that arose during an internal container registry migration. This caused service pods to crash.
### \*\*How we fixed it:\*\*
We identified the stale image and redeployed the correct version, restoring the service.
### \*\*What we are doing to prevent it from happening again:\*\*
We are hardening our image deployment pipeline and adding validation checks to ensure container registry migrations do not result in stale or incorrect images being deployed to production.
