I'm assuming someone is trying to fix this problem (which has been popping up every once in a while) right now, creating this error but i have no way of knowing that for a fact.
It wouldn't surprise me if a lot of work is done by volunteers btw, I'm happy that they do
How about www.arduino.cc? That's the problem site.
