The OpenNet Initiative releases country studies based on our ongoing research. The country studies are concise, high-quality research and analysis of Internet filtering in states of interest. These studies synthesize our initial background research, which sets the political and legal context of Internet filtering, with a broad identification of the current information technology infrastructure and an analysis of our preliminary technical testing results. Country studies are necessarily brief and represent an initial investigation to discover trends and sensitive areas. ONI will follow up on some country studies with intensive contextual research and rigorous in-country testing for our major national and regional reports.
