Getting started was extremely easy Getting started was extremely easy. I was testing multiple domains within minutes for the most basic checks which was great. The only thing I could possibly suggest would be to have support for a domain-centric view so I could see multiple tests (ie https, dns, etc) for one domain. Unless I missed this somewhere.

Good Easy to setup and good response time when things go down

Pretty good for anything less than 5 9s Uptime.com is pretty decent, but the UI can be a bit clunky and counterintuitive to use at times. Limited to 4 9s (i.e. 99.99%) uptime monitoring, anything higher is treated as 100% so if you need to measure 5+ 9s then you should look elsewhere.

Clean, fast and reliable. Kind of set up and forget tool. Once configured and tested, makes it's work in the most unobtrusive way possible.

Website Life Saver We use Uptime.com to monitor TorontoRentals.com and it gives us peace of mind knowing the second we have any site connectivity issues Uptime will send a text message to us. This happened earlier this year after business hours. I received an Uptime notification that some of our main city URLs went down, I quickly called one of our developers to troubleshoot the server issue and within minutes we had our city URLs back online rendering properly. Without Uptime we would have caught the issue the following morning causing a lot of site visitors to land on 404 urls.
