As the ongoing US-Israel-Iran conflict enters its third week, concerns are escalating over the safety of undersea internet cables in the Strait of Hormuz and Red Sea. These regions, now marked by mines, missile strikes, and attacks by the Houthi movement, host vital digital infrastructure that carries nearly all global internet traffic, including banking systems, artificial intelligence operations, and everyday communications.
Experts and officials warn that any disruption could slow connectivity across Asia, Africa, and Europe, while repair ships remain unable to access damaged cables due to ongoing hostilities. Governments, telecom operators, and international agencies are closely monitoring the situation, even as calls grow for restraint to prevent both economic and digital fallout.
Fragile Digital Lifelines Under Fire
The world’s dependence on undersea fibre-optic cables is both immense and often overlooked. An estimated 95% of global data traffic ranging from financial transactions and cloud computing to video calls and messaging flows through these cables laid across ocean floors. The Red Sea alone hosts around 15-20 major cable systems connecting Europe with Asia and Africa, while additional routes pass through the Strait of Hormuz, making these regions critical digital junctions.
Telecom experts have warned that these cables are particularly vulnerable in narrow maritime choke points, where multiple lines run in close proximity. A senior network analyst noted that “a single incident in these corridors could create cascading effects across continents,” slowing internet speeds, delaying financial transactions, and disrupting services that billions rely on daily.
Officials from global telecom bodies have acknowledged the risks, stating that contingency routes exist but are limited in capacity and could lead to congestion if major lines are severed.
Adding to the concern is the inability to carry out timely repairs. Cable repair ships, which are highly specialised and limited in number, require stable and secure conditions to operate. However, ongoing naval deployments, floating mines, and missile threats have effectively blocked access to affected areas.
Maritime advisories issued in recent days have warned vessels including repair crews to avoid high-risk zones altogether. Industry stakeholders have urged governments to establish temporary safe corridors, but no such guarantees have materialised so far.
Escalation In Strategic Waters
The current risks stem from a broader escalation involving the United States, Israel, and Iran, which has increasingly spilled into maritime domains. The Strait of Hormuz through which roughly a fifth of the world’s oil supply passes has witnessed heightened military activity, including reported mine deployments, drone surveillance, and missile exchanges. At the same time, the Red Sea has seen repeated disruptions linked to attacks by the Houthi movement, who have targeted commercial and strategic vessels.
According to international observers and defence officials, over a hundred commercial ships have faced delays or rerouting due to safety concerns, with some vessels stranded near critical choke points. Statements from U.S. defence authorities indicate that recent operations have aimed to neutralise threats to maritime security, particularly those targeting shipping lanes and infrastructure. Meanwhile, Iranian officials have signalled that the strait remains a strategic lever, fuelling uncertainty about future access and safety.
Global leaders and multilateral organisations have voiced concern over the widening scope of the conflict. A United Nations official recently emphasised the importance of protecting civilian infrastructure, including digital networks, warning that their disruption could have humanitarian consequences far beyond the immediate conflict zone.
Analysts also note that previous incidents such as accidental cable damage caused by ship anchors or natural disasters have already demonstrated how even minor disruptions can affect millions. In a conflict setting, the scale and intent of such damage could be far more severe.
The Logical Indian’s Perspective
The unfolding crisis serves as a powerful reminder that in today’s interconnected world, the impact of conflict extends far beyond borders and battlefields. Undersea cables may be out of sight, but they are the backbone of modern life supporting education, healthcare, commerce, and human connection.
The Logical Indian believes that safeguarding critical global infrastructure must be treated as a shared responsibility that transcends political divisions. While nations may have competing interests, the preservation of systems that enable communication and cooperation should remain non-negotiable.
