Sweet website

Sometimes you go to a website you've visited many times before and you find that it's not answering. So, what's the problem? Is the site down? Is there a problem on my side? How do I find out? Well, now there seems to be an answer; the site downforeveryoneorjustme.com. You just got to love that name.
The question now is, if downforeveryoneorjustme.com is down, is it down for everyone or is it just me?
