Undersea cables for Africa’s web retrace historical past and depart digital gaps as they join continents

Must read


Giant elements of west and central Africa, in addition to some nations within the south of the continent, had been left with out web providers on 14 March due to failures on 4 of the fibre optic cables that run under the world’s oceans. Nigeria, Côte d’Ivoire, Liberia, Ghana, Burkina Faso and South Africa had been among the many worst affected. By noon on 15 March the issue had not been resolved. Microsoft warned its clients that there was a delay in repairing the cables. South Africa’s News24 reported that, whereas the reason for the injury had not been confirmed, it was believed that “the cables snapped in shallow waters close to the Ivory Coast, the place fishing vessels are prone to function”.

Jess Auerbach Jahajeeah, an affiliate professor on the College of Cape City’s Graduate College of Enterprise, is at the moment writing a e book on fibre optic cables and digital connectivity. She frolicked in late 2023 aboard the ship whose crew is chargeable for sustaining most of Africa’s undersea community. She spoke to The Dialog Africa in regards to the significance of those cables.

1. What’s the geographical extent of Africa’s present undersea community?

Fibre optic cables now actually encircle Africa, although some elements of the continent are much better related than others. It is because each private and non-private organisations have made main investments prior to now ten years.

Based mostly on an interactive map of fibre optic cables, it’s clear that South Africa is in a comparatively good place. When the breakages occurred, the community was affected for just a few hours earlier than the web visitors was rerouted; a technical course of that relies upon each on there being various routes accessible and company agreements in place to allow the rerouting. It’s the identical as driving utilizing a instrument like Google Maps. If there’s an accident on the highway it finds one other technique to get you to your vacation spot.

However, in a number of African nations – together with Sierra Leone and Liberia – a lot of the cables don’t have spurs (the equal of off-ramps on the highway), so just one fibre optic cable really comes into the nation. Web visitors from these nations mainly stops when the cable breaks.

Naturally that has enormous implications for each side of life, enterprise and even politics. While some communication will be rerouted through satellites, satellite tv for pc visitors accounts for solely about 1% of digital transmissions globally. Even with interventions equivalent to satellite-internet distribution service Starlink it’s nonetheless a lot slower and far more costly than the connection supplied by undersea cables.

Mainly all web for normal folks depends on fibre optic cables. Even landlocked nations depend on the community, as a result of they’ve agreements with nations with touchdown stations – highly-secured buildings near the ocean the place the cable comes up from underground and is plugged into terrestrial methods. For instance southern Africa’s web comes largely via connections in Melkbosstrand, simply exterior Cape City, and Mtunzini in northern KwaZulu-Natal, each in South Africa. Then it’s routed overland to varied neighbours.

Every fibre optic cable is extraordinarily costly to construct and to take care of. Relying on the technical specs (cables can have extra or fewer fibre threads and allow totally different speeds for digital visitors) there are complicated authorized agreements in place for who’s chargeable for which points of upkeep.

2. What prompted you to jot down a e book in regards to the social historical past of fibre optic cables in Africa?

I first visited Angola in 2011 to begin work for my PhD venture. The web was all however non-existent – sending an electronic mail took a number of minutes on the time. Then I went again in 2013, after the South Atlantic Cable System went into operation. It made an unimaginable distinction: abruptly Angola’s digital ecosystem was up and working and all people was on-line.

On the time I used to be engaged on social mobility and the way folks in Angola had been enhancing their lives after an extended battle. Unsurprisingly, having digital entry made all types of issues attainable that merely weren’t possible earlier than. I picked up my curiosity once more as soon as I used to be professionally established, and am now writing it up as a e book, Capricious Connections. The title refers to the truth that the cables wouldn’t do something if it wasn’t for the infrastructure that they plug into at numerous factors.

Touchdown centres equivalent to Sangano in Angola are fascinating each due to what they do technically (connecting and routing web visitors everywhere in the nation) and since they usually spotlight the complexities of the digital divide.

For instance, Sangano is a outstanding excessive tech facility run by an extremely competent and socially engaged firm, Angola Cables. But the college just a few hundred metres from the touchdown station nonetheless doesn’t have electrical energy.

Once we take into consideration the digital divide in Africa, that’s usually nonetheless the fact: you may convey web all over the place but when there’s no infrastructure, abilities or frameworks to make it accessible, it may stay one thing summary even for individuals who reside proper beside it.

When it comes to historical past, fibre optic cables observe all types of fascinating world precedents. The 2012 cable that related one facet of the Atlantic Ocean to the opposite is laid nearly precisely over the route of the transatlantic slave commerce, for instance. A lot of the essential cable map is layered over the routes of the copper telegraph community that was important for the British empire within the 1800s.

Most of Africa’s cables are maintained at sea by the outstanding crew of the ship Léon Thévenin. I joined them in late 2023 throughout a restore operation off the coast of Ghana. These are uniquely expert artisans and technicians who retrieve and restore cables, generally from depths of a number of kilometres below the ocean.

After I frolicked with the crew final 12 months, they recounted as soon as by accident retrieving a bit of Victorian-era cable once they had been making an attempt to “catch” a way more latest fibre optic line. (Cables are retrieved in some ways; a technique is with a grapnel-like hook that’s dragged alongside the ocean mattress in roughly the correct location till it snags the cable.)

There are some very attention-grabbing questions rising now about what is often referred to as digital colonialism. In an atmosphere the place information is commonly referred to with phrases like “the brand new oil”, we’re seeing an essential change in digital infrastructure.

Beforehand cables had been often financed by a mix of private and non-private sector partnerships, however now large non-public corporations equivalent to Alphabet, Meta and Huawei are more and more financing cable infrastructure. That has severe implications for management and monitoring of digital infrastructure.

Given all of us rely a lot on digital instruments, poorer nations usually have little alternative however to simply accept the phrases and situations of rich company entities. That’s doubtlessly extremely harmful for African digital sovereignty, and is one thing we needs to be seeing much more public dialog about.
