   postmortem
   **Root Cause Analysis** **Incident Summary:** On August 19th, 2026, users in the EU Production environment experienced intermittent issues accessing Career Site functionalities. **Impact:** Users experienced intermittent failures while accessing Career Site functionality, resulting in degraded user experience and partial service disruption during the incident window. **Root Cause:** The issue was caused by a sudden increase in traffic that temporarily exceeded the available service capacity during scaling activity. Due to the service's sensitivity to startup time, the newly provisioned capacity was unable to stabilize quickly enough to handle the increased traffic. This resulted in intermittent service failures. **Resolution:** The service capacity and scaling configuration were adjusted to maintain sufficient baseline capacity and better accommodate sudden increases in traffic. The affected service was also redeployed to restore stability. **Preventive Measures:** * Scaling configuration has been optimized to better respond to sudden traffic increases * Additional capacity and startup behavior are being monitored to reduce the likelihood of recurrence
