Bookmarklet: Check if a website is down

Drag this link: down? to your bookmarks toolbar for a button that checks downforeveryoneorjustme.com to see if the website you just failed to load is actually down, or if you just have a problem getting to it.

Here's the code:

(function(){
  document.location = 'http://downforeveryoneorjustme.com/'
    + encodeURIComponent(location.host);
})()
