(Another) New Monitoring IP (important for monitors behind a firewall)

Tip: While using Uptime Robot until now, if you didn't need to do anything with the IPs of the service, then feel free to skip this post. Actually 99.9% of the users don't need this info.

Around a month ago, we had shared that a new IP was added to our engine to strengthen the system.

However, we experienced that, rather than distributing the engine into small pieces (servers), distributing it into huge ones will end up in a much better performance -what were we thinking: )-.

And now, we have that huge engine ready and will be activated by 11 January 2011 and some other IPs will become obsolete.

Until now, if you had whitelisted (or blacklisted) the IPs of Uptime Robot, please add:

  • into your list as the new IP.

Also, starting by 1 February 2011:

  • will no longer be in use.

Please feel free to ask anything in the comments or as a support ticket ([email protected]).

P.S. All IPs used can be found in the About page.

If you find Uptime Robot useful, help us spreading the word:

    Great service! Do you intend to share it on github?

    Still receiveing loads of false positives lately…
    Any chance on ftp/ssh port checks vs just http(s)?

    That’s not the plan for now but don’t know if this changes in the future.

    We had a bug in ping monitoring that sent false-positives but totally fixed now.
    Yes, we’ll be adding port checks.

    I also get false positives as a server in the route to the server I am monitoring via a ping sends a ping back if the server isn’t reachable – Perhaps you could implement something to ensure the IP of the ping is the same as the IP being monitored?

    That’s a very nice suggestion and added it to our to-do-list.

    Any chance of some IPV6 monitors, so that we can monitor our IPV6 services? That would be a really cool addition!

  9. admin Post author


    Yes, we’ll be adding IPv6 support very soon.

    Can you support IPv6 monitor?
    When I input a IPv6 address, it reports invalid.

    Yes, we’ll be adding the IPv6 update. Working on a big update that will include several other features too (otherwise, the IPv6 support is actually “on” in our test server).
