Status

A probe runs every minute and the result is recorded whatever it says. The service reports one of three states: operational, degraded or down. In the uptime number a down minute counts in full and a degraded minute at 30%; the bars themselves show every recorded minute unweighted.

This page reads two public endpoints that need no API key, so you can check it against its own source or point your own monitor at them: /health and /health/history. More on how failures are handled and refunded in Trust and reliability.
