[ PROD 2 ] - Pipelines Running Slowly

Incident Report for Harness

Postmortem

Incident Overview

Our monitoring systems detected pipeline loading slowness due to an unexpected traffic surge that consumed significant system resources. While there was no service downtime, users experienced degraded performance for approximately 45 minutes.

Root Cause

Primary Cause: Traffic surge overwhelmed existing system capacity

Mitigation Actions

✅ Immediate Response:

  • Scaled up system resources to handle increased load
  • Added additional capacity to restore normal performance
  • Monitored system recovery and performance metrics

✅ Resolution:

  • Performance restored to normal levels
  • No data loss or service interruption occurred

Next Steps & Improvements

Enhanced Load Balancing

  • Goal: Improve traffic distribution across resources
  • Benefit: Better handling of traffic surges and improved performance

Improved Alerting & Monitoring

  • Goal: Earlier detection of performance issues
  • Benefit: Reduced impact duration and faster response times
  • Implementation: Enhanced monitoring thresholds and alert mechanisms
