The Locus of filtering indicates where Internet traffic is blocked. C indicates that traffic is blocked from a
central location, normally the Internet backbone, and affects the entire state equally. D indicates that
blocking is decentralized, typically implemented by ISPs. (Note that this study does not include filtering
at the institutional level, for example, cybercafe ´s, universities, or businesses.)
Consistency measures the variation in filtering within a country across different ISPs where applicable.
Concealed filtering reflects either efforts to conceal the fact that filtering is occurring or the failure to
clearly indicate filtering when it occurs.
Transparency and accountability corresponds to the overall level of openness in regard to the practice
of filtering. It also considers the presence of concealed filtering, the type of notice given to users regarding
blocking, provisions to appeal or report instances of inappropriate blocking, and public acknowledgement
of filtering policies.
