During January 2025, Tom Whitwell focused on refining the logging infrastructure for the govuk-one-login/authentication-frontend repository. He addressed a maintenance and data exposure concern by removing the integration that sent Cloudfront logs to Splunk, updating the associated Cloudfront template to reflect this change. Using Terraform and applying DevOps best practices, Tom ensured the logging stack was simplified, reducing operational overhead while maintaining system stability. His work demonstrated careful change management, with clear commit messages and traceability in Git history. This targeted bug fix improved the security posture and maintainability of the cloud infrastructure without introducing new features during the period.
