This section of the website will give you useful information about website monitoring.

First of all, why you have to monitor your websites? There's a lot of reasons to do so. Downtime is always a bad thing, especially when visitors of your website inform you about it. It can cost you reputation and money. And no matter how reliable your servers are sometimes failures occur. And if you notice that failure not after several hours but after five minutes you can react very fast and maybe your visitors won't even know there were some problems.

Pingoscope is the right tool for that job. It watches your website (or anything you asked to watch) day and night. It helps you increase overall uptime of watched servers.
