I've just been trying to download the newest version of inkscape (over the direct link to the exe file), but the file had 0 bytes. So I thought I'd go to the sourceforge.net homepage, but it was empty! Nothing, not even a bit of html...

Having the same problem. Sourceforge send back a tcp rst (reset) so I end up getting a blank page.

Oh, now they say so themselves. At 0:00 CET their new announcement was online, saying that they are sorry for the inconvenience. Good, now at least we know they're working on it.
