I want to know if my web server is down for some reason, so I started thinking of ways to get notified if the service gets interrupted.

There are ways to set up e-mail or sms notifications from the server itself. The problem is that when your whole server goes down, who’s going to notify you then? The answer is simple, I need an external notification system

I came across a website called UptimeRobot. It is a free service and I am now trying it out

It actually is just as easy as they say, you’ll only need to do a very simple registration and then insert your website URL

There is a dashboard, where you can monitor your resources

You can send tests to see if the system works. This free plan has options to set the monitoring interval to 5 minutes, which in my opinion is more than enough for a site like this. With paid plans the interval can be set to 30 seconds
