Root Cause Analysis
A deployment configuration was unintentionally changed during earlier testing and was not restored before the next production release. Although the application build completed successfully, the hosting platform could not locate the generated assets, causing requests to return errors.
Resolution
We identified the incorrect configuration and restored it to the expected value, then redeployed the application. Service was fully restored within seven minutes of the initial report.
Remediation and Preventive Actions
Add automated validation to confirm that production build outputs are present and deployable before a release is promoted.
Manage hosting configuration through version-controlled infrastructure rather than manual project settings.
Avoid configuration changes during release windows unless they are required for the release and independently reviewed.
