Repair operations on the West Africa Cable System (WACS) submarine fibre-optic network have entered a critical phase, with the designated repair vessel sailing towards the fault location.
The deployment follows a 29 October circuit disruption that affected Congo Telecom’s redundancy mechanisms. Technical teams isolated the suspected fault to the cable segment linking the Democratic Republic of Congo (DRC) and the Republic of Congo.
Although the exact coordinates of the damage have not been publicly disclosed, an official update from Congo Telecom confirmed that the repair vessel is scheduled to reach the affected area on Wednesday, 11 November, to begin physical restoration of the undersea link.
The Gulf of Guinea and Central African coastal waters are known locations for submarine cable faults. Disruptions along this Atlantic seabed corridor can result from deep-sea seismic activity, maritime incidents such as anchor dragging, or underwater landslides in geographical features such as the Congo Canyon.
The latest disruption follows WACS outages, including underwater landslides that affected the network in 2020 and August 2023, as well as a separate outage in January this year that disrupted internet traffic across the region.
“Congo Telecom is closely monitoring the evolution of the situation and remains attentive to the progress of operations,” the operator said.
“We will continue to keep customers informed of further developments as new information becomes available.”
Spanning 14,500 kilometres, the WACS network connects South Africa with Portugal and the UK.
With landing stations in 14 countries, including the Republic of Congo, Gabon, Cameroon, Nigeria, Ghana and Côte d’Ivoire, the infrastructure serves as an international backbone for regional data transit and internet connectivity across Central and West Africa.
