**Issue Summary:** On May 6, 2026, users in the UK Production environment, including UK SL1, SL2, and SL3, experienced intermittent errors within Reporting 2.0. The issue occurred for a brief duration and resulted in occasional request failures and delays. **Root Cause:** The issue was caused by transient service instability within the Reporting 2.0 application flow. This instability temporarily impacted request processing for a subset of requests, resulting in intermittent HTTP 500 error responses. **Corrective Action:** The impacted application service was restarted to restore normal request processing. After the recovery action was completed, service stability was restored and Reporting 2.0 functionality returned to normal. **Preventive Measures:** To reduce the risk of recurrence, Cornerstone is taking the following action: * Reinforcing application stability checks to support faster detection and recovery in the event of similar transient service interruptions.
