TL;DR
Repeated submarine cable cuts in the Middle East have disrupted global internet traffic, prompting Europe to consider Arctic cable routes for resilience. The plan faces technical and financial hurdles, but geopolitical tensions accelerate interest.
Recent submarine cable cuts in the Red Sea and Persian Gulf have disrupted internet traffic across Africa, Asia, and the Middle East, prompting discussions about alternative routes, including Arctic cables, to improve resilience.
The disruptions began in 2024 when a missile strike on a cargo ship in the Bab-el-Mandeb Strait severed multiple cables, taking months to repair due to the delicate nature of submarine cable repair work in conflict zones. Further cable severances in September 2024, likely caused by commercial vessel anchors, compounded the problem, highlighting the vulnerability of current routes.
These repeated incidents have led to a shift away from traditional routes through the Red Sea and Persian Gulf, with governments and companies exploring overland routes and, notably, proposals for Arctic cables to connect Europe and Asia. The European Union has endorsed the Arctic route, allocating funds and conducting surveys to develop two cables crossing the North Pole and the Northwest Passage, aiming to reduce reliance on geopolitically unstable regions.
Why It Matters
This development matters because the current reliance on submarine cables passing through conflict-prone regions exposes global internet infrastructure to significant risks. The move toward Arctic cables reflects an effort to enhance resilience, reduce latency, and improve European data autonomy amid geopolitical tensions, especially involving Iran and the Middle East.
However, the technical challenges and high costs associated with Arctic cable installation and maintenance could limit the feasibility of these routes. The outcome will influence future global data infrastructure planning and regional security strategies.

Background
Most of the world’s data traffic runs through submarine cables established since the telegraph era, with key choke points in the Middle East. Recent conflicts, particularly involving Iran and Yemen, have caused multiple cable severances, disrupting international connectivity. Historically, efforts to develop Arctic cables have faced technical hurdles, notably ice scour damage from icebergs and the difficulty of maintaining cables in extreme conditions. Previous Arctic projects, like Quintillion, suffered from repeated damage and high repair costs, discouraging large-scale deployment. The current geopolitical climate has increased interest in Arctic routes, with the EU actively supporting new projects to diversify global connectivity options.
“The Persian Gulf will never go back to what it was before, when the Iranians wouldn’t dare assert control.”
— Roderick Beck, cable industry veteran
“The cable would make Europe’s data infrastructure more resilient, lower latency between the EU and Asia, and strengthen Europe’s autonomy.”
— Pär Jansson, Senior Vice President at GlobalConnect
“What if there is damage to the cable from ice scour? Repair can only happen in summer, making Arctic cables very challenging.”
— Alan Mauldin, research director at TeleGeography

What Remains Unclear
It is still unclear whether the Arctic cable projects will overcome the technical, environmental, and financial hurdles. The long-term viability and actual deployment timelines remain uncertain, as does the geopolitical support beyond initial planning stages.

What’s Next
Next steps include conducting detailed route surveys, securing funding, and developing specialized ice-capable cable ships. The EU plans to complete surveys this summer, with full construction potentially years away. Monitoring of geopolitical developments and technological advances will influence project progress.

Key Questions
Why are submarine cables so vulnerable to damage?
Submarine cables are vulnerable due to natural hazards like ice scour and human activities such as anchor dragging and fishing. Conflict zones also pose risks, making repairs complex and time-consuming.
What are the advantages of Arctic cables over traditional routes?
Arctic cables could bypass conflict-prone regions, reduce latency, and increase resilience by diversifying global internet infrastructure. They also offer environmental monitoring opportunities.
What technical challenges do Arctic cables face?
Harsh environmental conditions, including icebergs, extreme cold, and difficult maintenance, make Arctic cables expensive and complex to install and repair.
How soon could Arctic cables be operational?
While surveys are underway, actual deployment could take several years, with full operation possibly not before the late 2020s or early 2030s, depending on funding and technological progress.
