Logging Everything Is Not a Strategy
"Log it just in case" feels like insurance. What it actually buys is a haystack, a storage bill, and a search that times out during the incident you bought it for.

Logs Are Written for the Wrong Reader
Most log lines are written by someone who already knows what the code does, for a reader who doesn't and won't be able to ask.
Config Changes Are Deploys
A config edit can change production behavior as completely as a code change can, and in most places it does so with none of the review, testing, or staged rollout that code gets.
Every Setting Is a Deferred Decision
Most config options exist because someone couldn't decide, or didn't want to. The knob ships, the decision never gets made, and everyone downstream inherits the question.
Nobody Knows What the Config Actually Is
The value a service runs with is assembled from defaults, files, environment variables, a remote store, and per-tenant overrides. Very few systems can tell you what won.
Every Alert Is a Claim About a Person
An alert isn't a statement about a metric. It's an assertion that a specific human should stop what they're doing and act — and most alerts were never designed to earn that.
The Response Is Part of the Alert
An alert that fires correctly and leaves the person receiving it with no idea what to do has done half a job. The response isn't downstream of the alert — it's the reason the alert exists.
You Alert on the Failures You've Already Had
Alert rules accumulate one incident at a time, which means your coverage is a map of your history — not of the ways your system can actually break.
A Rollback Is Not a Time Machine
Rolling back a deploy feels like undoing it. Mostly it undoes the code. Everything the bad code already did to your data, your queues, and your downstream systems is still there, waiting.
Both Versions Are Running
A deploy isn't a moment when the old code becomes the new code. It's a window where both are live at once, reading and writing the same data — and most deploy surprises live inside that window.
