**Incident Summary:** On April 23rd, 2026, clients in the US RES Production environment experienced intermittent service degradation. During this period, users encountered intermittent request failures and partial application accessibility issues. **Impact:** Users experienced intermittent latency and occasional request delays while accessing services during the incident window, resulting in degraded application responsiveness. **Root Cause Analysis \(RCA\):** The issue was attributed to transient performance degradation during a period of elevated system activity. This led to temporary delays in database-level request processing, causing intermittent latency and request failures. **Resolution:** As an immediate mitigation, system configurations were optimized to improve performance during peak activity. Additional performance tuning and stability enhancements were implemented to restore normal service responsiveness and stabilize the environment. **Preventive Measures:** The following preventive measures have been implemented to reduce the likelihood of recurrence: * Applied system performance tuning to better handle peak usage conditions. * Implemented additional optimizations to improve database request handling and overall system stability.
