Regions
Public monitors run from one or more regional probes. Each region runs its own independent schedule against your monitor; if one region sees a failure, an incident opens with that region attached to the cause.

Choosing regions
- One region - fine for staging, internal dashboards, anything where you just want to know it's reachable somewhere.
- Multiple regions - production. Lets you distinguish a global outage from a regional network blip, and surfaces issues like a CDN POP misbehaving.
- Default -
us-eastif you don't pick.
Each selected region multiplies the number of checks counted toward the monitor's interval - a 60s check from 3 regions runs every 20s on average from one of them, but each individual region still checks every 60s.
What region selection doesn't do
- It doesn't apply to DNS monitors - DNS resolves from a single location today.
- It doesn't apply to Lighthouse-bound monitors - those run from your agent inside your network. See Lighthouse.
Network paths
All regional probes egress from datacenter ranges. If your service allow-lists IPs, contact us for the current egress list - the set isn't published as a stable contract because we add and rotate regions.
