We are very happy, have been using it for years and never had a problem. They have static IPs in the case you need to setup an access list on your dmz. Set it and forget it. Weekly we also have emailed reports or the downtime of the week/months. We rely on it a lot too as our top tier support get directly paged by it. We cannot say anything bad about it. They respond quickly to support request and emails too. Highly recommend it.

We not only need to know when our site is down, but we also need to know if we have introduced errors into other processes like our checkout, signing in, checking our customer portal etc.

I've been using them for years to monitor several of our website, going from basic monitoring to some vary advanced tools over the years. They've been responsive to our needs and quick to help any time I've needed it. I use several software products to monitor what I have going on, but AlertBot is easy one to use.

We generally know there is an issue before any 3rd party vendor long before the vendor reports an issue now. The best part is we get a heads up before a customer calls.

Easy to use, great Customer Service/Support Team.
