As the US‑Iran war continues into its fifth week with no clear end in sight, fears about global internet disruptions are rising sharply due to the strategic vulnerabilities of undersea fibre‑optic cables in the Red Sea and Strait of Hormuz key chokepoints for global digital traffic.
Although Tehran has not directly threatened to cut these cables, Iran‑aligned Houthis in Yemen have expanded their military role and issued threats against regional shipping routes, heightening concerns about deliberate or collateral damage to critical infrastructure.
In response, India’s telecommunications regulator has asked operators to prepare contingency plans, while global markets including India’s IT stocks have reacted nervously to the risk of subsea cable outages that could hamper cloud services, online payments, and AI workloads.
Global Internet at Conflict Risk
Undersea internet cables are the hidden backbone of the modern digital economy, carrying nearly all international data traffic from emails and video calls to financial transactions and cloud computing services. Tens of thousands of kilometres of fibre‑optic lines run along the ocean floor, linking continents and enabling the seamless flow of data that billions of people and businesses depend on. In the Red Sea alone, dozens of such cables cross one of the world’s most strategic maritime corridors, connecting Europe, Asia, and Africa.
Recent reports suggest that part of Meta’s 2Africa submarine cable project, which was planned to enhance connectivity across the Gulf region and beyond, has been paused amid the conflict, illustrating how even ongoing infrastructure projects are being affected.
While accidental damage such as the September 2025 incident where cables were severed by a ship’s dragged anchor can be repaired when conditions allow, a deliberate attack or extended conflict could create far longer outages, complicating repairs in contested waters.
India’s Digital Lifeline and Economic Stakes
India is particularly exposed to these risks. The country hosts 17 submarine cables across 14 landing stations in cities including Mumbai, Chennai, Cochin, Tuticorin, and Trivandrum, which together handle a substantial volume of the nation’s international internet traffic. Experts note that roughly two‑thirds of this traffic is routed through Mumbai, making the system vulnerable to bottlenecks and performance issues if cables in the Red Sea or Hormuz region are damaged or disrupted.
During the 2025 Red Sea outage, India experienced slower speeds and latency issues, though broad internet access did not collapse. However, given India’s deepening reliance on digital services including online banking, digital payments, cloud storage, and AI technologies any significant break in connectivity could have cascading economic impacts, from slowed business operations to reduced productivity and potential revenue losses for tech and financial sectors.
Reflecting these concerns, India’s Department of Telecommunications has issued guidance to telecom firms and subsea cable operators to assess and plan for potential disruptions. This includes exploring alternate routing, redundancy measures, and collaboration with international partners to ensure continuity of service.
Meanwhile, Indian markets have already felt effects: IT stocks fell as investors grew wary about the possibility of internet infrastructure risks slowing growth or affecting earnings for tech firms reliant on global connectivity.
Escalation in the Middle East Broadens Strategic Risks
The geopolitical backdrop has grown increasingly volatile. Across the conflict zone, there is evidence of broadening involvement by Iran‑aligned forces, including the Houthis in Yemen, who have launched ballistic missile attacks on Israel and continue to threaten regional shipping routes. This marks a notable shift, as the Houthis had largely avoided direct engagement earlier in the war.
At the same time, global energy chokepoints have also become flashpoints. The Strait of Hormuz through which an estimated one‑fifth of the world’s oil supplies flow has been largely closed to commercial traffic, disrupting global energy markets and pushing prices higher. Some observers warn that both the Red Sea and Hormuz have effectively become dual chokepoints for modern civilisation’s critical infrastructure.
In parallel, there are mixed signals diplomatically; reports indicate that US President Donald Trump may be willing to end the war even if the Strait of Hormuz remains closed, while Iranian officials categorically deny participating in direct talks and accuse the US of planning a ground invasion.
The Logical Indian’s Perspective
The threat to the global internet a resource that has become essential to everyday life, education, trade, health, and governance serves as a stark reminder of how interconnected modern civilisation has become. These cables, largely unseen beneath the waves, are as crucial to global communication as roads and bridges are to physical commerce. Yet they are uniquely vulnerable to geopolitical instability and conflict.
The escalating tensions in the Middle East underscore how technological infrastructure and geopolitics now intersect in ways that directly affect ordinary citizens across continents. The Logical Indian believes that protecting critical infrastructure should be a priority for all nations, and that diplomacy, peacebuilding, and international cooperation must be pursued earnestly to prevent such conflicts from inflicting broader harm on the digital lifelines of millions.
