Probe IP addresses

Uptime Room checks your endpoints from the regions below. If a firewall, WAF or rate limiter sits in front of a monitored target, allow these addresses so checks are not blocked and counted as downtime. The same list is available as JSON from GET /api/regions (egress) - poll it from automation; it is cached for five minutes.

Identifying our requests

Checks arrive from the addresses above with the method, headers and body you configure on the monitor (set a custom header such as X-Uptime-Room: 1 if you want to recognise them). Heartbeat monitors are the reverse: your job pings us, so nothing needs allow-listing. See the API reference for the monitor fields.
