UptimeRobot

Monitors are frequently not working, reporting state 30-40 minutes late, or not at all. I have 2 accounts and 1 account may report correctly (e.g. 7 minutes of downtime) while the second doesn't (e.g. won't detect the service is up for 40+ minutes). This happened 5+ times in the past 6 months with no explanation, solution or refund. The latest being last night where different monitors reported widely different uptime, failing to detect a service is back up for 30+ minutes. The uptime charts it generates are wildly inaccurate and it is one of the reasons I picked this product in the first place. Right now, I have a monitor that should be up, but isn't. I contacted their support saying guys, here, a reproducible case: it is clearly broken, please investigate. Their solution? - oh just delete your 3 years of uptime history and it should work because it is "stucked in cache". When I said I do not wish to delete 3 years of uptime history, they said: "what I'm saying is to reset the stats so our checks can be done again" - when I reluctantly deleted the 3 years of history and the monitor showed as online, their response? - see, there is no problem! There are no words.

Really easy to setup and follow. My go to tools to monitor uptime and SSL.

Have 4 monitors running every minute, for a number of years now. Never experienced UptimeRobot not being available. Very satisfied so far.

When I downgraded my 300 monitors plan to 200, I ended paying more! Why? Because they increased their prices a lot. Their excuse? "We didn't increase our prices for several years, so we doubled them this year". It's an incredible situation. The service has not got better, they've just taken their customers hostage, knowing that creating 200 monitors with another service wouldn't be worth the time spent.

Have been using UptimeRobot for nearly 5 years now and although I generally don't like receiving alerts about servers being down, I do like looking at green uptime charts in the great new mobile app! Great job!

I have used it for years, and it never failed to inform me if something went wrong. The recent revamp made it even better: more features at hands, easier-to-use design. The price to value ratio also makes me happy!

One of the easiest tools to set up and use I've ever found. It's great for having quick and seamless access to the uptime of all my different sites. Personally, I had looked at a bunch of other tools, but nothing else came close. And it's FREE! Hard to beat that. :)
