Locations and IPs.
Here is the list of our IPs so you can allow-list them if needed.

Download all IPs for allow-listing in .txt, JSON or directly from DNS
IMPORTANT: We’ve updated our monitoring infrastructure and are rolling out new IP addresses. Starting July 28th, UptimeRobot will begin using the new IPs listed below in production, replacing the old ones.
If you’re using a firewall, you must update your rules and whitelist the new IPs to ensure uninterrupted monitoring.
To make this easier, we’ve released a dedicated API that always returns the latest list of UptimeRobot monitoring IPs. Click on “JSON” to access it.
UptimeRobot uses a distributed monitoring system to minimize false-positives.
All initial checks are performed from the same region using randomly selected servers (IPs). When an issue is detected, we verify the downtime by conducting additional checks from different servers and providers within the same region.
Allow-listing.
If the monitoring works well for you, there is no need to take any action. However, if you receive any false positives, there is a strong chance that the IPs used are blocked by your hosting provider. Learn more about all the reasons for monitor downtime in detail.
Please make sure that you allow-list these IPs so that any requests that UptimeRobot send are not blocked.
