# Error monitoring

Whether a failure in production reaches a human rather than sitting in a log nobody opens.

## Why a check from outside cannot see it

Whether a failure reaches a human happens after the response is sent. A visitor sees an error page. Nobody outside can see whether anyone was told.

## How to check it yourself

1. Add a route or a button that throws a deliberate error in production.
2. Trigger it once, then put your phone down and wait five minutes.
3. If nothing told you, you have no monitoring. Wire one alert to somewhere you actually look.

## What a Launch Review does instead

A reviewer triggers a deliberate failure in production and records whether anything reached a person, and how fast.
