Historically, these attempts at disrupting communication have had mixed results. Kabila used a communications cut in 2015 with some success, but attempts in Egypt and elsewhere have failed -- if just because service eventually has to come back. And the Congo protests this time around promise to be particularly strong, with a normally divided opposition rallying together. An attempt to sever internet and SMS access may make it difficult to coordinate, but a sufficiently angry public will still find a way to make its voice heard.
