TL;DR
Repeated submarine cable cuts in the Middle East have disrupted global internet traffic, prompting interest in Arctic cable routes. The EU is exploring the Polar Connect project to improve resilience and reduce reliance on vulnerable corridors.
Recent disruptions to submarine internet cables in the Middle East, caused by conflict and accidents, are prompting European and global efforts to develop Arctic cable routes as a more resilient alternative.
In 2024, multiple submarine cables in the Red Sea and Persian Gulf were severed due to conflicts, including a missile strike on a cargo ship and anchor dragging by commercial vessels. These incidents caused significant internet outages affecting Africa, Asia, and the Middle East. Repairing these cables has been slow, often taking months due to the delicate nature of submarine cable repairs and the risks posed by conflict zones. As a result, policymakers and industry leaders are considering alternative routes, with the Arctic emerging as a promising option. The EU has designated the Polar Connect project, led by Nordic research and telecom entities, as a key initiative to establish two Arctic cables crossing the North Pole and the Northwest Passage, aiming to improve resilience and reduce dependency on traditional routes like the Red Sea and Russia-controlled pathways.
Why It Matters
This development is significant because it highlights vulnerabilities in the current global internet infrastructure and the geopolitical risks associated with traditional submarine cable routes. The Arctic cables could enhance Europe’s data security, lower latency, and provide strategic independence, especially amid ongoing conflicts in the Middle East and tensions involving Russia and Iran. The initiative also signals a shift toward more resilient infrastructure planning in the face of increasing geopolitical instability and climate change impacts on Arctic conditions.

Background
Submarine cables carry over 90% of global internet traffic, with major routes passing through the Red Sea, Persian Gulf, and Russia. Disruptions in 2024, including a missile strike on a cargo ship in the Bab-el-Mandeb Strait and anchor dragging incidents, have exposed the fragility of these routes. Historically, Arctic cables have faced technical and environmental challenges, such as ice scour from icebergs and the difficulty of maintenance during winter months. The Quintillion project, launched in 2016, encountered repeated iceberg damage, illustrating the technical hurdles. The EU’s recent focus on Arctic routes reflects a strategic shift driven by these vulnerabilities and the desire for greater data sovereignty.
“The Persian Gulf will never go back to what it was before, when the Iranians wouldn’t dare assert control.”
— Roderick Beck
“The cable would make Europe’s data infrastructure more resilient, lower latency between the EU and Asia, and strengthen Europe’s autonomy.”
— Pär Jansson
“Icebergs can drag along the bottom of the ocean floor, digging long grooves and damaging cables. Repairing them is very challenging.”
— Alan Mauldin

What Remains Unclear
It remains unclear whether the Arctic cable projects will be financially viable given the high costs and technical challenges, or if geopolitical tensions will accelerate their development. The long-term effectiveness of Arctic routes in extreme weather and ice conditions is still uncertain, and the timeline for full deployment is not yet established.

What’s Next
Next steps include completing the planned route survey for the Polar Connect project this summer, securing additional funding, and addressing technical challenges such as ice management and repair logistics. The project aims to begin construction within the next few years, with operational cables expected in the late 2020s or early 2030s.

Key Questions
Why are submarine cables in the Middle East vulnerable?
The cables are vulnerable due to geopolitical conflicts, accidents such as anchor dragging, and targeted attacks, which can cause prolonged outages and impact global internet traffic.
What advantages do Arctic cables offer over traditional routes?
Arctic cables could provide more resilient, less politically sensitive routes, lower latency between Europe and Asia, and greater strategic independence for Europe and other regions.
What are the main technical challenges in deploying Arctic cables?
Challenges include ice scour damage from icebergs, extreme weather conditions, high costs of specialized ice-capable ships, and difficulties in maintenance and repair during winter months.
How soon could Arctic cables become operational?
If planning proceeds smoothly, construction could start within the next few years, with operational cables possibly in the late 2020s or early 2030s.
