Blank page on contao.org with Safari Mac

On Safari 5 and 6 on Mac OSX, the page http://www.contao.org/en/ is completely blank and there is no source code. I've also tested with all cookies enabled, and with the application launched in French and English. My two other colleagues have the same problem, is it the same for anyone here?

Now, it works again, so we can close the topic.
