Senior Policy Advisor - Africa, of the Internet Society, Verengai Mabika, on 10 April 2018, posted about Internet shutdowns1 happening in Chad due to ongoing political unrests. In the report he mentions about the continuous disruptions of Internet and social media services since the 2nd of April; although it is not the first occurrence in 2018. There were earlier reports of Internet shutdowns in Chad in January 2018 and also a much longer 8-months social media cutoff in 2016 during the elections.
Quartz2 also reported the Internet shutdown in Chad, and in fact mentions disruptions since 28 March 2018.
Another country in Africa - under the grip of a longtime authoritarian leader - has blocked social media and access to independent news. This time, it's #Chad. https://t.co/t53oPc38zN @Lattif

In September last year I wrote about an Internet shutdown in Togo3 and the Anti-shutdown policy proposal4 under discussion within the AfriNIC community.
