TL;DR If your incident workflow starts with editing code, you're likely wasting time. Start with: environment dependencies wiring contracts Then check the code. Most modern backend failures are system-state issues, not logic bugs. The mistake I kept making I wasted hours debugging functions that were never broken. The real issue was almost always the system. After enough incidents, a pattern became obvious: Most backend bugs today are not code bugs. They are system state bugs. Why this happens We still follow an outdated debugging model: Find the function Rewrite it Retry That worked when systems were simpler. It breaks in modern backends where behavior depends on: environment variables service dependencies startup/lifecycle order API contract alignment dependency versions In other words: The system matters more than the function.…
