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

GBPretty 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.

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

GBGood tools Good tools, responsive support, seems to still be maturing as some basic functionality available in competing services is not available.
