## Impact
The Close Web UI was unavailable for 15 minutes from 2025-01-06 17:33 to 2025-01-06 17:48.
## Root Cause and Resolution
A change to our deployment process introduced a build where JavaScript file contents were updated without corresponding filename changes, leading to caching issues that caused outdated files to be served. We quickly rolled back to a previous build to restore services and then resolved the underlying issue by updating the affected assets.
