Nairobi, Kenya — Experts say Africa needs to invest in robust infrastructure if the continent is to have reliable internet after recent outages due to underwater cable failures highlighted the continent’s reliance on single-path connectivity. Disruptions in March and May caused online banking problems and communication delays. Businesses experienced interruptions in many countries. In March, on the Atlantic coast of West Africa, four submarine cables that deliver the internet to at least 17 countries went offline. Less than two months later, Eastern and Southern Africa experienced outages after two undersea cables were damaged. In Tanzania, the U.S. Embassy in Dar es Salaam closed for two days due to the disruption. Ben Gumo, a Kenyan who relies on the internet to sell clothes, shoes and children’s wares, said he lost business during the May disruption. “Someone … puts stuff in the [online] basket, but because of the outage he cannot complete the sale, so he cancels,” Gumo said, adding that he couldn’t update his website with new products. According to the telecommunications research company Telegeography, over 100 cable cuts occur globally each year. Experts blame undersea volcanic activity, rock falls, recent rainfall and currents in rivers that are much stronger than when some of the cables were built. Manmade activities also cause disruptions. According to one report, a ship was attacked in the Red Sea and drifted, its anchor pulling up three underwater cables. Mike Last works with the West Indian Ocean Cable Company, which operates in 20 African countries and has built 36 data centers. He said recent disruptions prompted government officials and businesspeople to recognize the need for better internet infrastructure. “What it made people realize is that you have to invest in a reliable network, you have to invest in redundancy,” Last said, meaning that internet service is provided by more than one source. “We’ve seen a real boom in clients coming to us wanting connectivity on the new subsea systems.” Some countries can stay online when one internet source is cut off, although service is often slow and not stable, because service providers and telecommunication carriers invested in more than one international connection. According to the World Bank, sub-Saharan Africa’s digital infrastructure coverage, access and quality are far behind those of other regions. However, Africa is embracing the digital future. According to the Submarine Cable Networks, 37 countries have at least one subsea cable connection, and 20 countries have more than two subsea cables. Last said cables planned by Google and Meta will improve connectivity. One of the new cables, he said, has a high capacity. Another new cable — named 2Africa and led by Meta, the parent company of Facebook — is being built all the way around Africa. “It brings a lot of capacity to Africa, and that will help,” Last said. Experts warn that disparities in connectivity across Africa are expected, but that the development of infrastructure, government policies and private sector investments can accelerate growth.
