Measuring the Internet for Freedom
ROME – Last year, during a wave of deadly political protests in Ethiopia, the government blocked more than 15 media websites and the smartphone chat application WhatsApp. Sites promoting freedom of expression and LGBTQ+ rights, as well as those offering censorship-circumvention tools, such as Tor and Psiphon, were also suppressed.
All of this was uncovered through the use of software called ooniprobe, which is designed to measure networks and detect Internet censorship. Ooniprobe was developed more than five years ago by the Tor-supported Open Observatory of Network Interference (OONI), with which I work, in order to boost transparency, accountability, and oversight of Internet censorship. The software is free and open source, meaning that anyone can use it. And, indeed, tens of thousands of ooniprobe users from more than 190 countries have already done just that.
Those users have contributed to the collection of millions of network measurements, all of which are published on OONI Explorer, arguably the largest publicly available resource on Internet censorship. Thanks to their use of ooniprobe, we uncovered the extent of last year’s wave of censorship in Ethiopia, as well as details of many other cases of censorship elsewhere in the world.
