Down For Everyone or Just Me

And incredibly useful and simple utility site that I can't believe I haven't heard of before. Down For Everyone or Just Me lets you enter a url and checks itself, that way you can see if the site you're checking is down to the whole world or if it's a problem that is specific to you. Everything I could think of was either up, or made up, but I plan to use this next time one of the sites I frequent goes down.
