Simple, reliable, and saved my bacon at least once!

I've been using Uptime Robot for several years to monitor a side project of mine, and it's always been great at that. At first, I was on the free tier, but I was happy to start paying for usage once it was appropriate. It impressed me a few weeks ago when it caught an SSL certification expiration before it happened. My hosting provider had a defect this year that prevented the cert from auto-renewing like normal. Without UptimeRobot, this would have caused an outage impacting 50,000 users. They didn't have to create this feature, but they did.

Best server status monitoring service

UptimeRobot is among the services that have conquered my heart. It's great that the free version also provides a lot of possibilities, that it can track the server status very successfully and detect the slightest changes.

Great product, reasonably priced

It is nice to know that my sites are up and you can't be the pricing. I run several sites for clients and it is a good feeling to know that their sites are up.
