I noticed that SourceForge and Google code both are blocking access to the platforms for people from a number of countries (Iran, Syria, Cuba, ...).
As far as I understood, Savannah is also US-based. Is there the danger that Savannah will also block access from these countries?
We talked about it recently at FOSDEM and LSM, and our answer is that we do not block people based on their country.
In addition, the FSF investigated the legal issue and the conclusion is that US law does not require blocking connections from anywhere.
Note: SourceForge softened their policy a bit: http://sourceforge.net/blog/some-good-news-sourceforge-removes-blanket-blocking/
The country-based restrictions are in place by default, but you can turn them off in the sf web pages, under: Develop -> Project Admin -> Project Settings -> Export Control.
We don't know about Google Code.
