Nearly all studies of online censorship in Cuba, such as the OpenNet Initiatives May 2007 study, depend on secondary sources, and most point to Julien Pains October 2006 report Going Online in Cuba for Reporters Without Borders as an authoritative account. Pain found that there are two types of internet connections in Cuba: a national one that just lets you use an e-mail service operated by the government, and an international one with access to the entire Internet. While the national connection is available at Interet cafes throughout the island that are accessible for ordinary Cubans, the international connection is highly restricted and expensive. Still, Pain found that:
There is hardly any censorship of the Internet in Internet cafes. Tests carried out by Reporters Without Borders showed that most Cuban opposition websites and the sites of international human rights organisations can be accessed using the international network. In China, filtering for key-words makes it impossible to access webpages containing subversive words. But, by testing a series of banned terms in Internet cafes, Reporters Without Borders was able to established that no such filtering system has been installed in Cuba.
On the other hand, he claims that in cyber-cafes that offer the cheaper national connection:
Users have to give their name and address at the door. If they write something containing suspect key-words, such as the name of a known dissident, a pop-up message appears saying the document has been blocked for state security reasons. Then the application word processor or browser that was used to write the text is automatically closed. So it seems that a programme installed in all Internet cafes automatically detects banned content.
But it is difficult to determine whether Pain actually entered one of these national cyber cafes, and Salim Lamrani points out in a July 2009 piece that Reporters Without Borders coverage of Cuba has long been inconsistent.
