TL;DR
Cable cuts in the Middle East, especially in the Red Sea, have disrupted global internet traffic, leading to increased interest in Arctic submarine cables. The EU is exploring plans to build Arctic routes to improve resilience and reduce reliance on traditional choke points.
Recent disruptions to submarine fiber optic cables in the Middle East, caused by conflicts and accidents, have exposed vulnerabilities in global internet infrastructure, prompting European and global policymakers to consider Arctic routes as an alternative.

In 2024, a missile strike on a cargo ship in the Bab-el-Mandeb Strait damaged multiple submarine cables, disrupting internet traffic across Africa, Asia, and the Middle East. Repair efforts faced delays of months due to the delicate nature of cable splicing and the risks posed by ongoing conflict zones.
Following these disruptions, several cable projects in the Persian Gulf were halted or rerouted, with experts noting that the region’s cable infrastructure has been fundamentally altered. The US and Israel’s recent military actions against Iran further complicate the situation, limiting the feasibility of traditional routes through the Red Sea and Gulf.
As a result, European officials and industry leaders are increasingly exploring alternative routes, notably through the Arctic. A European Union panel has recommended building two Arctic cables—one through Canada’s Northwest Passage and another across the North Pole—to bypass vulnerable choke points and improve resilience. The Polar Connect project, led by Nordic research and telecom organizations, has received €9 million in EU funding for preliminary work, with full costs estimated around €2 billion.
Why It Matters
This development is significant because it reveals the fragility of current global internet infrastructure, which relies heavily on a handful of submarine cable routes passing through conflict-prone regions. Building Arctic cables could enhance Europe’s data sovereignty, lower latency, and improve resilience against future disruptions. It also signals a geopolitical shift, as nations seek to secure critical infrastructure in strategic Arctic territories amid rising tensions in traditional choke points.

Background
Most of the world’s internet data travels through undersea cables, with critical routes passing through the Red Sea, Persian Gulf, and Russia. Disruptions in 2024, including missile strikes and accidental damage, have underscored vulnerabilities in these routes. Historically, attempts to establish Arctic cables date back over 20 years, but ice conditions and maintenance challenges have prevented successful deployment until now. The EU’s renewed interest reflects both technological and geopolitical motivations to diversify and secure internet infrastructure amid ongoing conflicts and climate change impacts in Arctic regions.
“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 VP at GlobalConnect
“What if there is damage from ice scour? It’s very challenging to repair in Arctic conditions.”
— Alan Mauldin, research director at TeleGeography
What Remains Unclear
It remains unclear whether Arctic cable projects will proceed to full deployment given the high costs, technical challenges, and geopolitical considerations. The long-term viability of Arctic cables depends on advances in icebreaker technology and the political will of Arctic nations and Europe.
What’s Next
Next steps include completing the planned survey for the Polar Connect project this summer, securing additional funding, and addressing technical challenges such as ice damage and repair logistics. Monitoring developments in Arctic geopolitics and climate conditions will be crucial for the project’s future.
Key Questions
Why are submarine cables vulnerable to damage?
Submarine cables are vulnerable due to natural hazards like ice scour and earthquakes, as well as human activities such as anchoring, fishing, and military conflicts.
What are the main challenges of Arctic cable projects?
Challenges include extreme weather conditions, ice damage, high installation costs, and difficulties in maintenance and repair, especially during winter months.
How would Arctic cables improve internet resilience?
Arctic cables would provide alternative routes that bypass conflict zones and traditional choke points, reducing the risk of widespread outages caused by regional disruptions.
When could Arctic cables become operational?
Full deployment is likely several years away, contingent on successful surveys, funding, and overcoming technical hurdles. The earliest estimates suggest operational cables could be in place within the next decade.
