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.

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!

UptimeRobot is a great product. It keeps me well informed on the status of my client's websites.

Just AMAZING, I love the App, helps me keep up to date with whats going on with my VPSs. Great Job!

Top product for its price. UptimeRobot does what is does, no more, no less. And that is what is needed. I now use it for over 1 year and I've seen different options added as extra functionality and for stability. At the moment there are some things I miss, but who knows, perhaps this will change in the (near) future. Two things I miss are widgets for the Android homescreen and an overview dashboard so I can use a big screen monitor to have an overview at a glance. Now you have to scroll in a long list. But for now, still 6 stars out of 5!!!
