The complete Stack Exchange data dump up to September 2014 is ready and can be found hosted on the Internet Archive. The latest can always be found here:

The torrent is now available here:

It takes a bit of time for archive to process the massive amount of data we send their way.
Enjoy sharing and remixing, but remember to attribute the source if you publish your own versions of this data.
