The ACE (African Coast to Europe) submarine cable runs along the west coast of Africa between France and South Africa, connecting 22 countries. It extends over 17,000 km, and has a potential capacity of 5.12 Tbps. The cable system is managed by a consortium of 19 telecommunications operators & administrations, and the first phase entered service in December 2012. While it may not have been completely problem-free over the last 5+ years, online searches do not return any published reports of significant outages caused by damage to the cable.
However, on March 30, damage to the cable disrupted Internet connectivity to a number of connected countries, with reported problems posted to social media over the next several days. These posts indicated that the ACE submarine cable was cut near Noukachott, Mauritania, but did not provide any specific information about what severed the cable.
