   **Issue Summary:** On March 2, 2026, clients hosted in the US SL2 Production environment experienced a temporary service disruption affecting the Career Site. During the incident window, users encountered intermittent slowness and brief periods of unavailability while accessing the Career Site. **Root Cause:** The incident was caused by an unexpected surge in traffic to the Career Site during off-hours. The elevated request volume temporarily exceeded available application capacity, resulting in service instability. **Corrective Action:** Cornerstone Engineering teams increased application capacity to stabilize performance and restore normal service levels. System performance was monitored following the adjustment to confirm that service stability had been fully restored. **Preventive Measures:** To reduce the risk of recurrence, Cornerstone is implementing the following improvements: * Enhancing monitoring thresholds to detect sudden traffic spikes earlier and enable faster response. * Reviewing and adjusting capacity planning to better accommodate unexpected increases in traffic.
