Note about the download site

Some people encounters problems to access the downloads, their browser sounds like going in an infinite loop. This is probably due to the fact that in many companies, the IT service adds a proxy which forbids access to various web sites according to non-published rules, and sometimes this rule says to forbid access to an URL having a port number, which is not the case for the drupal site but for the download site, yes.

 If this arrives in your working place, simply try at home, it should work. We are working currently to find a better solution.
