There seem to be some strange things happening with some of the non-english wikipedias. For instance if you follow the Afrikaans link on the front page http://af.wikipedia.com/ it takes to a page about something called The TV Clubhouse. It seems to affect all the language wikipedias that are under wikipedia.com while the ones under wikipedia.org seem to work as normal. The simple english http://simple.wikipedia.com/ also seems to be affected.
