Trying to go to the main forum site (ie. the white button up above) gets me redirected to a hacker splash. Team R00t apparently, with sadly unimaginative politics.
Don't know if there are any other effects, and the rest of the forums are accessible through different avenues of approach, thus how I'm posting this.
Amateurs are depressing.
If no-one else if affected then I'll have more to look into personally, heh.
Edit: Yeah, seems to be tied to the top page of the forum itself. Any further down the tree seems unaffected.
