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: 74.86.158.107.

And, you can find the full list of IPs being used at: http://www.uptimerobot.com/about.asp .

Have a great day!

@Sudhir,

I suggest whitelisting the monitoring IPs mentioned at http://www.uptimerobot.com/about.asp

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

I would like to have option into my monitor services to view the entire month/year graph of all failure, not as it right now day by day.

Hi,

I'm very pleased with service functionality. Simple form and it doing exactly what I need :-)

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 uptimerobot.com. 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.

@Mike,

Uptime Robot catches 403 errors but maybe something different going on. Can you please let us know the details (support@uptimerobot.com)?

@Morteza,

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.

Chris Oct 28, 2013 at 8:08 pm

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

Thanks,

Chris
