Excited to share a nice move that will make Uptime Robot much more stable and eliminate any false-positives.

We’ll be starting to monitor websites from multiple locations (from US, Europe, Asia, etc.) to make 100% sure that they are “down” before sending any notifications.

It is all set now and we’ll be doing test monitoring starting today and the system will be activated fully by next week.

The remote checks will be done from URLs like,, etc. So, if you whitelist our IPs in your firewalls, analytics applications, etc, please whitelist * to make sure it will cover all remote locations.

  • Keyword checking (ability to check if a keyword exists or not in a webpage)
  • RSS alerts (get the alerts via RSS)


This is the biggest part that we have worked on.
