If you run a web site, you probably find yourself logging into it a few times a day, just to make sure it's still working properly. If so, here's a free web-based service that could save you time and help keep your site running even more smoothly.
The system is called Monitor Us, and you can find it at http://mon.itor.us. Sign-up is free, and once you're registered you can enter the URL of the sites you want to monitor. From now on, the system will "ping" your site every 60 minutes or so, and you can log in any time to see a graph of performance. The stats include the ping response time, and the percentage uptime of your site. So if there's been a problem at some point in the last day or so, you'll know about it.
