Small anomalies compound into catastrophic outages

Most catastrophic outages don’t start with dramatic failures - they begin with small anomalies that compound over time. A minor latency increase, an occasional timeout, a query that’s slightly slower than usual. None trigger immediate action, but left unaddressed, they become the foundation for systemic failures.

These “paper cuts” are a bandwidth problem, not a detection problem. Engineers already know about these issues - they’re buried in dashboards, buried in logs, buried in the team’s collective memory. But with limited resources, teams are forced to focus on immediate fires over long-term system health.

The key is making investigation fast and cheap. If diagnosing an issue takes an hour, engineers will naturally prioritize critical problems. But if you can reduce diagnosis time to minutes through better tooling and automation, teams can tackle small issues opportunistically between bigger projects. The goal isn’t to fix everything - it’s to make fixing small issues less expensive than ignoring them.
