As if three cable faults within the Pink Sea weren’t sufficient of a headache, a sequence of West African cables have been broken on March 14.
The exact location and reason for all of those faults should not recognized right now, however let’s take 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 is not clear right now if all 4 cables have been broken in the identical occasion or if some had pre-existing faults. These cables be part of the beforehand broken AAE-1, EIG, and SEACOM/TGN-Eurasia methods within the Pink Sea, which stay out of service.
Which international locations are most impacted?
Presently, there isn’t any official phrase on the entire fault areas.
The Nigerian Communications Fee initially indicated the harm was someplace between Senegal and Côte d’Ivoire. Different experiences have recognized the placement as instantly off Abidjan, Côte d’Ivoire. Late on March 15, MainOne introduced that their fault was certainly off of Côte d’Ivoire. The corporate state their preliminary evaluation of the fault trigger is seismic exercise, however may have extra perception as soon as the cable is repaired.
CloudFlare has noticed service disruptions for a number of international locations beginning south of Senegal, which can point out harm to at the least one cable someplace off the coast of Senegal and Gambia.
Assuming that’s the potential demarcation level for harm, right here’s an inventory of the coastal West African international locations south of this line, the variety of intercontinental cables linked to them, and their statuses:
For West African international locations that rely solely on one of many broken cables, this doesn’t imply they’ve misplaced entry to intercontinental connectivity. They may ship visitors subsea or terrestrially to different international locations that retain intercontinental cable connectivity. Methods nonetheless on-line embrace the brand new Equiano cable, in addition to EASSy, Glo-1, and Maroc Telecom West Africa.
Let’s additionally not neglect that landlocked African international locations like Botswana, Burkina Faso, Zambia, and Zimbabwe additionally depend on these cables for intercontinental connectivity and could also be impacted as properly.
How lengthy will it take to repair these cables?
The time is takes to restore a cable depends upon on many components 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 at all times simple as the placement of a cable might have shifted in the course of the fault.
- Fault restore – the variety of fibers and sort of injury play a job in restore size.
- Climate window – earlier than a restore begins, upkeep corporations should assess if the climate will stay appropriate for an extended 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 will take 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 have been as follows:
- ACE – 37 days
- SAT-3/WASC – 43 days
- WACS – 30 days

What’s the impression 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 out there, which can degrade the standard of service. Nevertheless, it’s vital to take into consideration which purposes and companies are used. In spite of everything, 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 might expertise elevated latency and packet loss. The corporate said it’s including extra capability and expects the issue to be resolved at this time, March 15.
Can satellites resolve this downside?
Probably not.
Submarine cables present much more bandwidth than satellites can. Satellites are actually helpful in guaranteeing important enterprise and governmental companies stay lively if fiber connectivity is impaired or misplaced totally. 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’d nonetheless account for lower than one-tenth the capability of a single, trendy fiber-optic undersea cable.
