Internet Censorship Capabilities in Cyprus: An Investigation of Online Gambling Blocklisting.

This paper presents the initial findings of an open and collective effort towards a cross comparison study of web-content blocking regulations and practices, in different parts of Cyprus. Our analysis is based on network measurement data collected by volunteers in Cyprus, using a custom OONI probe and open DNS resolvers, from five residential ISPs; Callsat (AS 24672), Cablenet (AS 35432), Cyta (AS 6866), MTN (AS 15805) and Multimax (AS 197792). We were able to identify a number of unreported Internet censorship cases, non-transparently implemented blocking regulations, and collateral damage due to blocking of email delivery to the regulated domains by the National Betting Authority of the Republic of Cyprus. These results indicate the presence of at least two distinct regimes on the island.
