Over 99% of intercontinental data travels through cables on the ocean floor, not satellites or wireless networks. The industry has quietly shifted its priority from raw bandwidth to survivability. A $16 billion build-out through 2029 is now explicitly designed around resilience, and not every region will benefit equally.
Failures Are Routine, Repairs Are Slow
Cable faults are not rare emergencies. The industry treats them as a steady operational baseline. Anchors drag, trawlers snag, and earthquakes shift seabeds. The 2022 Tonga eruption cut the island nation off for weeks. West Africa lost significant connectivity in early 2024 when cables in the same corridor were severed within days of each other.
Three things make recovery harder than it sounds. The global fleet of specialized repair ships is small and often out of position when faults cluster. Permitting across jurisdictions can stretch timelines from weeks to months. And many regions funnel all traffic through one or two chokepoints, so a single incident cascades.
Cable failures remain a leading cause of revenue loss in subsea infrastructure, and the question is never whether cables fail but how fast the system absorbs it.A Two-Tier Internet Is Forming
The $16 billion build-out is not evenly distributed. Projects like 2Africa are adding multiple landing points across the African continent and Southeast Asia. Hyperscaler-funded routes are multiplying across the Pacific.
Small island states and landlocked nations often depend on a single transit cable. When it cuts, the fallback is expensive satellite capacity: usable, but not at the latency or cost profile that supports cloud workloads, telemedicine, or financial services.
A region with three diverse cable landings behaves very differently under stress than one with a single corridor, and that gap is widening.
