All of these African countries have suffered major internet disruption this month: Ivory Coast, Liberia, Benin, Ghana, Nigeria, South Africa, Namibia, Burkina Faso. This meant people couldn’t do everyday things like post on social media, send money to each other or order taxis.

It’s because of damage to some of the underwater cables off the coast of west Africa. These cables, some only as thick as a garden hose, span thousands of miles and are responsible for most of the earth’s internet access.

BBC Africa business reporter Jewel Kiriungi tells the affected countries are dealing with being knocked offline.

And internet infrastructure expert Doug Madory explains how exactly this vast network of cables works and what might have happened to cause the online blackout.
