I always use http://isitup.org The owner of the script even has his script opensource which is downforeveryoneorjustme is using. That means isitup.org will always be the most up to date and accurate.
I really don't like sites like downforeveryone who use a free script but remove the link to the original creator. That's why I'd encourage everyone not to use it. isitup.org is also a far better and shorter domain.

I think you're wrong.
