DAILYOPS / READING ROOM
Find the work behind the work.
Field notes, systems thinking and operational analysis for people responsible for what runs.
From signal to evidence, then to a decision that can be defended.
DOSSIER 01 / OBSERVABILITY
When green does not mean healthy.
An indicator can describe a measurement without describing the service’s actual state. This dossier follows the path from signal to context, then to a decision that can be defended.
Everything Was Green. Everything Was Broken.
Your dashboards were green. CPU usage was low. Services were running. Yet users couldn't do their jobs. Here's why monitoring success doesn't always mean operational success.
02 / ObservabilityPrometheus & Grafana: Production Observability Stack
Minimum viable metrics pipeline: scrape architecture, RED/USE signals, SLO alerting, and on-call routing without alert fatigue.
03 / InfrastructureKnowledge Silos: The Most Dangerous Single Point of Failure in IT
Your infrastructure may be redundant, monitored, and highly available - but if only one person knows how it works, your biggest outage is still waiting to happen.

There's Nothing More Permanent Than a Temporary Firewall Rule
That emergency firewall exception was supposed to last five minutes. Months later, it's still there - quietly expanding your attack surface.
