New Ip Address In Town

The number of users utilizing Uptime Robot is regularly growing and, in order to fulfill this growth, a new monitoring engine will be added to the system by this Monday (2 July 2012).

If you never needed to whitelist Uptime Robot's IPs to make the monitoring work correctly, than it is ok to ignore this message as things will keep working ok.

However, if your monitors/websites are behind a firewall where you need to whitelist the IPs, the new IP is:

And, you can find the full list of IPs being used at: .

Have a great day!

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

    Also, whitelisting the e-mail IP (mentioned in the same URL) in your e-mail server will help a lot.

    I started using this yesterday to monitor our site for “403.9 – Too Many Users errors”. There have been lots, but none showing on my account with I guess the software doesn’t see this as a downed web site. Shame, but your software is of no use to me if this is the case. Thanks anyway.

    SMS messages are sent via free e-mail-to-SMS gateways and they are not stable for all providers. We’ll be adding a pro gateway option soon.

    This would be a great paid service but as it is free, it is a tremendous aid to any webmaster.
