"Between 2016 and 2021, 68 shutdowns have been documented in 29 African countries. This demonstrates that government-mandated internet disruptions are an established norm in the region, despite very little scientific or social evidence demonstrating their effectiveness. A number of pointers and factors signal the likelihood of an internet shutdown occurring.
