Root Cause Analysis:
An update to the authentication logic for accessing the Proxyclick Web Application and APIs was mistakenly marked as deployed to production in a previous release but was included for the first time in the scheduled deployment on March 28, 2023. While this update worked without issue in all pre-production environments, a code defect was present which was unable to handle the higher load of the production environment.

The investigation into the cause of the outage was delayed by the incorrect deployment record, as the team initially excluded the authentication components of the application. Significant time was spent reviewing incorrect logs and service components as a result. Once this was corrected the teams found the underlying issue, then created and deployed a hotfix patch to bring the outage to a close.

Preventative Action and Analysis:
Engineering and QA teams will implement better load-scaling into pre-production testing to reduce the potential for similar issues in future. Engineering and Product teams will review the deployment process to improve accuracy of release records. Incident management processes will be updated to ensure all logging sources are checked earlier in the investigation.
