Is redsn0w.us the real redsn0w website? Or is it a fake?

I accidentally went to that webpage to get redsn0w since when googling redsn0w that was the first result so I thought that was the official website.
I then read that you should only download it from blog.iphone-dev.org
Is redsn0w.us the official website or is it just a "fake" website?

It is a fake/real site
