As if three cable faults within the Pink Sea weren’t sufficient of a headache, a collection of West African cables had been broken on March 14.
The exact location and trigger of those faults will not be identified presently, however let’s have a look at what we do know.
Which cables are broken?
Primarily based on experiences from a number of community operators within the area, the next cables are broken:
It isn’t clear presently if all 4 cables had been broken in the identical occasion or if some had pre-existing faults. These cables be a part of the beforehand broken AAE-1, EIG, and SEACOM/TGN-Eurasia techniques within the Pink Sea, which stay out of service.
Which nations are most impacted?
Presently, there is not any official phrase on the fault places.
The Nigerian Communications Fee indicated the harm was someplace between Senegal and Côte d’Ivoire. Different experiences have recognized the placement as instantly off Abidjan, Côte d’Ivoire.
CloudFlare has noticed service disruptions for a number of nations beginning south of Senegal, which can point out harm to at the very least one cable someplace off the coast of Senegal and Gambia.
Assuming that’s the doable demarcation level for harm, right here’s a listing of the coastal West African nations south of this line, the variety of intercontinental cables linked to them, and their statuses:
For West African nations that rely solely on one of many broken cables, this doesn’t imply they’ve misplaced entry to intercontinental connectivity. They might ship visitors subsea or terrestrially to different nations that retain intercontinental cable connectivity. Techniques nonetheless on-line embody the brand new Equiano cable, in addition to EASSy, Glo-1, and Maroc Telecom West Africa.
Let’s additionally not overlook that landlocked African nations like Botswana, Burkina Faso, Zambia, and Zimbabwe additionally depend on these cables for intercontinental connectivity and could also be impacted as effectively.
How lengthy will it take to repair these cables?
The time is takes to restore a cable is dependent upon on many elements together with:
- Permits – upkeep vessels require permits from governments when repairs are required inside their waters.
- Loading – the restore vessel might want to go to a depot to load spare cable to accommodate the broken cable.
- Transit time – it takes time for a restore vessel to achieve the realm of suspected harm.
- Fault location – finding the broken portion of the cable is just not all the time simple as the placement of a cable could have shifted throughout the fault.
- Fault restore – the variety of fibers and kind of injury play a task in restore size.
- Climate window – earlier than a restore begins, upkeep firms should assess if the climate will stay appropriate for a protracted sufficient interval to make the restore.
Repairs will virtually actually be swifter for these West Africa cables in comparison with these within the Pink Sea, the place allowing challenges and ongoing Houthi assaults portend prolonged delays.
Whereas every restore scenario is exclusive, we are able to have a look at the August 2023 repairs off of the West African coast close to Angola and the Democratic Republic of Congo as a tough information. Primarily based on TeleGeography’s Submarine Cable Faults Database, the variety of days to restore these cables had been as follows:
- ACE – 37 days
- SAT-3/WASC – 43 days
- WACS – 30 days

Word: The information proven is restricted to what has been disclosed to the general public.
What’s the influence on shoppers and enterprises?
Community operators routinely carry their visitors throughout a number of cables in case of outages like this one. Numerous cable outages reduces the quantity of capability obtainable, which can degrade the standard of service. Nevertheless, it’s necessary to bear in mind which functions and companies are used. In any case, not all consumer exercise generates intercontinental visitors. Many companies will proceed to function usually.
On the time of writing, Amazon’s AWS cloud platform is just not reporting any points in South Africa, neither is Google Cloud. Microsoft has indicated some customers of their Azure cloud platform could expertise elevated latency and packet loss. The corporate said it’s including further capability and expects the issue to be resolved at the moment, March 15.
Can satellites clear up this drawback?
Not likely.
Submarine cables present much more bandwidth than satellites can. Satellites are actually helpful in making certain very important enterprise and governmental companies stay energetic if fiber connectivity is impaired or misplaced fully. Nevertheless, satellites are capacity-constrained.
In the event you put collectively all of the capability from Starlink, Amazon Kuiper, and different new satellite tv for pc constellations, they might nonetheless account for lower than one-tenth the capability of a single, trendy fiber-optic undersea cable.
