This article explores the example of Cuba in order to understand how a contentious politics has evolved since the 2000s and especially after the semi-liberalisation of internet access in 2008. My aim is to analyse how use of new technologies impact the fragmented arenas of contention that already existed in Cuba. My argument is that they have reinforced existing dynamics, while creating new channels of expression and linkage, between contentious spaces within Cuba and with specific segments of the Cuban diaspora. Those dynamics have in turn allowed for the emergence of a transnational Cuban public arena and a more intricate contentious space in Cuba itself.
