UptimeRobot: Free Website Uptime Monitoring Tool

Israel Nicolas 10-03-2010

Managing several websites can be very tricky – you need to check the security of servers, double-check your source codes, study web analytics, and monitor their uptime. If you have several websites, something is bound to go wrong. Fortunately, Uptime Robot is a free app that alerts you if your website goes down. This allows you to act on the problem and fix your website as quickly as possible.

Once you register and log in, you can add as many as 50 websites that you want to monitor. You can add any website – even those that you do not own. The app then smartly checks your websites’ status every 5 minutes.

Uptime Robot does much more than ping your site. First, it searches for websites headers and get status codes like “200-ok” and “404-not found”. If the website does not load, Uptime Robot will perform more checks for the next three minutes. If the website is still down after several checks, the app will alert you through e-mail or SMS. You can also let the app alert multiple contacts to let your friends know when something goes wrong.

All of your added websites are listed neatly and color-coded for easy status checking. Green means the website is up while red means the website is down. Other colors include Grey for “not checked”, Yellow (seems off), and black (paused).

Uptime Robot is a useful tool for website administration and server maintenance. It is also ideal for people who want to check the uptime of their favorite websites.

    Thanks very much for the inclusion to the MakeUseOf directory.

    The error might have happened while we restarted our web server. However, the Uptime Robot engine is on an other machine which still continues to check websites and alert users even the website is off.

    P.S. But I agree that this is funny :).
