Repeated submarine cable cuts in the Red Sea and Persian Gulf have disrupted global internet traffic, leading Europe to explore Arctic cable routes for increased resilience. The plan faces technical and financial challenges but reflects growing geopolitical concerns.
Recent disruptions to submarine fiber optic cables in the Middle East, caused by conflicts and accidents, have heightened concerns over global internet resilience, leading European officials to pursue alternative Arctic routes.
Over the past year, multiple submarine cables in the Red Sea and Persian Gulf have been severed due to military conflicts and commercial accidents, disrupting internet traffic across Africa, Asia, and the Middle East. Repair efforts have faced delays because cable repair ships cannot operate safely in war zones, often taking months to restore connectivity.
This situation has prompted policymakers and telecom companies to consider alternative routes that bypass these chokepoints. The most ambitious plan involves laying fiber optic cables across the Arctic, connecting Europe to Asia via the Northwest Passage and the North Pole. The European Union has designated this project as a ‘Cable Project of European Interest,’ investing around 9 million euros in preliminary work, with full costs estimated at approximately 2 billion euros.
Why It Matters
This development is significant because it addresses the vulnerability of the current global internet infrastructure, which heavily relies on a handful of underwater cables passing through geopolitically unstable regions. Establishing Arctic routes could enhance data resilience, lower latency, and strengthen Europe’s technological independence. However, technical challenges related to ice, maintenance, and costs remain substantial hurdles.

Background
Since 2024, the Red Sea and Persian Gulf have experienced multiple cable cuts, attributed to conflicts, anchor dragging, and natural hazards like ice scour. Previous Arctic cable projects, such as Quintillion, faced failures due to ice damage and logistical difficulties. The EU’s renewed interest reflects a broader strategic shift to diversify critical infrastructure amid increasing geopolitical tensions and climate change impacts on Arctic conditions.
“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
“Icebergs can drag along the bottom of the ocean floor, digging grooves and damaging cables, making Arctic cables very challenging to maintain.”
— Alan Mauldin, research director at TeleGeography

What Remains Unclear
It remains unclear whether the Arctic cable project will proceed to full construction, given the high costs, technical challenges, and environmental risks. The timeline for deployment and the potential geopolitical opposition are also still uncertain.

What’s Next
The upcoming summer survey will assess the feasibility of the Arctic cable route. If the project advances, detailed planning and negotiations will follow, aiming for potential construction within the next few years. Meanwhile, efforts to improve resilience of existing cables continue.

Key Questions
Why are submarine cables so vulnerable?
They are vulnerable due to natural hazards like ice scour and storms, as well as human actions such as military conflicts and accidental damage from ships dragging anchors.
What are the main challenges of Arctic cable routes?
Technical difficulties include ice damage, high costs of specialized ships and icebreakers, and long repair times during winter months when repairs are impossible.
How will Arctic cables improve internet resilience?
They would provide alternative pathways that bypass conflict-prone regions, reducing reliance on a few chokepoints and lowering the risk of widespread outages.
When could these Arctic routes become operational?
If planning proceeds smoothly, construction could begin within the next few years, with operational status possibly achieved by the late 2020s or early 2030s.
