Short summary

Production bugs demand structured investigation: gather evidence from multiple sources, reproduce systematically, and isolate the failing component. For severe incidents, rollback may restore service faster than debugging; keep fixes minimal and tested. Post-mortems and pattern recognition prevent recurrence—most issues fall into familiar categories like API changes, caching bugs, or environment misconfigurations.

• •Gather evidence and reproduce before guessing—avoid assumptions about the root cause
• •For critical incidents, rollback may restore service faster than finding and fixing the bug
• •Post-mortems and pattern recognition help teams prevent recurrence of common issues
