Locations and IPs

So that you know the origin of the requests...

Uptime Robot uses a distributed monitoring system to minimize false-positives.

All primary checks are made from the main engines in Dallas-USA. However, once a downtime is detected, secondary requests to verify this downtime is sent from remote nodes that are located in different countries/continents.

Whitelisting

If the monitoring works well for you, there is no need to take any actions. But, if you get any false/positives, there is a strong chance that the IPs used are blocked by your hosting provider.

Please make sure that you whitelist these IPs so that any requests that Uptime Robot send are not blocked.

Locations and IPs

The main monitoring location is in Dallas-USA and there are other nodes in other countries/continents to verify down statuses.
