Postgres Troubleshooting Labs

Debug real database outages in live environments.

Practice Postgres incident response with broken replicas, slow queries, and recovery workflows.

  • Replication and failover
  • Performance regressions
  • Data integrity checks
  • Live terminal access

Theory-only DB training

  • No real incidents
  • No live systems
  • Static examples
  • No time pressure

Deadnodes labs

  • Production-like outages
  • Live debugging
  • Timed scenarios
  • Root-cause focus

Postgres incident cases

Investigate replication lag, vacuum issues, and storage failures in live environments.

  • Slow queries
  • Replica drift
  • Disk pressure

Full-stack context

Database failures often cascade into services. Diagnose the incident across the stack.

  • App symptoms
  • Service impact
  • Recovery steps

For DevOps and SRE

Use scenarios for training, interviews, or team assessments.
