No, not this site (you're looking at it, right??), but this one: http://downforeveryoneorjustme.com/
It's so simple, just click the link, type in the web domain/address and hit enter and know if it's a problem with the site, or it's just you ;)
You can even short-cut the typing and click on pre-made links, like this one:
http://downforeveryoneorjustme.com/planetskaro.org.uk
See, this site's still running isn't it :D
