Incident Overview

During a one-time renewal deployment process for front-end assets, a global configuration update of Azure Front Door was required across both the general Azure platform and the US GCC platform. While the changes were successfully applied to the general Azure platform, the US GCC platform encountered issues due to platform-specific configuration differences.

It is important to emphasize that service degradation was not expected during this process. However, incomplete propagation of configuration changes on the US GCC platform necessitated additional manual adjustments, resulting in temporary disruption loading the Course Catalog, Course Homepage and My Training Dashboard web parts
