Ada's Ping Tool
Ping is an invaluable tool for testing whether a site is up or not. It sends a packet of information to the site's address, and waits for a reply from it. If you don't get a response from Ping for your site, the chances are it's currently down. Let my Ping tool test the connectivity of your site!
