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

IMPORTANT: On April 8th we updated our core monitoring infrastructure, adding these new IPs:

2406:da1c:9c8:dc02:82b2:f0fd:ee96:0579We have optimized our IPv6 addressing format by removing the /64 subnet prefix, ensuring compatibility with CloudFlare and other network security configurations.
We removed the IPs that were no longer in use.
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 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.
