Methodologies and tools for open dialogue in the defense of digital rights

Sursiendo is a Mexican organization working to defend digital rights in order to achieve a more open and collaborative environment. As part of Sursiendo’s work, the organization has accompanied social organizations in digital care by working to ensure that skill-building processes are closer to contexts and methodologies adapted to each reality. That is why Sursiendo believes that analyzing one’s own actions is essential to improving this approach. Sursiendo’s collaboration with OTF has contributed to this direction.

GFWatch: A Longitudinal Measurement Platform Built to Monitor China's DNS Censorship at Scale

The following blog post is authored by Information Controls Fellowship Program (ICFP) fellow Hoàng Nguyên Phong. As an ICFP fellow, Phong's research examines China’s DNS filtering mechanism, one of the techniques deployed by China's Great Firewall (GFW). DNS filtering is a process of interfering with DNS resolutions, which are used to map human-memorable domain names (such as "") to their hosting IP address(es), to prevent access to undesired content. Working with the host organization, Citizen Lab at University of Toronto, Phong built GFWatch, a measurement platform that allows researchers to continuously monitor the GFW’s DNS filtering behavior.
