Locations and regions

Regions define from which locations we check the monitored URL. By default, every monitor is checked from at least 4 different locations. To prevent false positives, an incident is created only after a check fails from at least 3 locations.

To configure monitoring locations, go to Monitors → Select a monitor → Configure → Advanced settings.

Bear in mind that removing locations from a monitor's configuration might increase the number of false positives as well as increasing the number of incidents.
