   postmortem
   **Root Cause Analysis** **Incident Summary:** On Oct. 1st and again on Oct. 2nd, 2026, users across the FRA SL1 Production environment experienced issues accessing Learner Home. **Impact:** Affected users experienced difficulties loading Learner Home and increased response times, resulting in a degraded learning experience. **Root Cause:** The incident was caused by elevated resource utilization in the FRA SL1 Production environment. This affected the performance of backend application components, resulting in increased response times and intermittent errors. **Resolution:** The team implemented corrective configuration changes and took steps to improve resource utilization. Following these actions, Learner Home functionality recovered and the immediate incident was resolved. **Preventive Measures:** * The team has added additional capacity to the EU Production environment * Planned workload redistribution to improve resource utilization and balance the load across the environment * Monitoring will continue to identify potential performance degradation and help maintain service stability
