Damage to undersea cables is making access to the Internet increasingly difficult across Africa.
The Economist talks about it, specifying that the continent found itself "stuck" between two failures at crucial points on the planet.
On March 14, the Ghana Stock Exchange closed an hour later than usual after an Internet blackout interrupted trading.
Connection problems have forced a Nigerian cement company to cancel an earnings call.
According to NetBlocks, a digital research firm, data connectivity in Liberia and Benin has fallen to below 20% of normal levels.
In Côte d'Ivoire it fell to 3%.
Although some traffic has been restored, Wi-Fi remains unstable in a dozen countries, including South Africa.
The reason for all this trouble - explains the Economist - is that four of the main undersea data cables serving Africa, including the West African Cable System (WACS), were seriously damaged somewhere near Côte d'Ivoire just weeks after a more had been cut near Yemen.
MainOne, which operates one of the West African cables, says it has ruled out human causes (such as fishing) and believes the damage was due to seismic activity on the seabed.
Ghana's National Communications Authority believes it will take at least five weeks to resolve the problem.
