This section describes how the issue evolved.
On Wednesday, September 24, 2025, at 1:36 AM PT (8:36 AM UTC), an investigation began into reports of customers experiencing issues in the Runtime Manager UI. It was reported that customers were unable to view or manage their applications in Runtime Manager UI. They were able to use MMP (Mule Maven Plugin)/CLI/API as the temporary workaround. Customers using Design Center were unable to create, delete or rename API projects. The investigation identified that a change to the infrastructure impacted the Runtime Manager and Design Center UIs. The change was rolled back to the impacted services, ending the impact at 04:14 AM PT ( 11:14 AM UTC).

To address the identified root cause, MuleSoft commits to the following actions to help remediate the potential for these issues to occur in the future:
