**Incident Summary:** Starting April 13th, 2026, intermittent errors were observed in reporting functionality across US Production swimlanes \(SL1, SL2, SL3, and SL5\). **Root Cause Analysis \(RCA\):** The issue was caused by the auto-scaling mechanism. Newly provisioned nodes were not fully ready to handle reporting requests, leading to processing delays and request timeouts. **Corrective Action:** Auto-scaling \(scale-out\) has been temporarily paused. The system is currently operating on a fixed, increased server capacity without scale-in or scale-out to ensure stability. **Preventive Actions:** * Capacity has been proactively increased to handle expected load without relying on auto-scaling. * Additional nodes are being utilized with auto-scaling disabled to maintain consistent performance. * Engineering teams are working on enhancements to improve node readiness and ensure seamless scaling in the future.
