Most of the March data has been released to our page on Google Code. Included forge collections are: Free Software Foundation, Freshmeat, Rubyforge, Objectweb, Savannah, Tigris. Google Code is still running. Github and Launchpad are not functional right now (waiting on a bug fixes).
There are two ways to get the data:
You can download the data at our downloads page - the flat files are so marked, and the SQL files are marked "datamarts". Note that datamarts only contain the latest collection. If you want previous months' worth of data, you'll have to grab those datamarts too.
You can also log into our database on the Teragrid and live-query the data. Read these instructions on getting a login.
