The escalating conflict involving Iran, the United States and Israel is no longer being seen only as an energy and shipping crisis. It is also raising fears over the safety of Hormuz subsea cables and Red Sea cables that support some of the world’s most critical digital traffic. Experts say any serious damage to these routes would not shut down the entire global internet, but it could trigger major regional slowdowns, rerouting problems, financial network stress and broader global internet disruption across markets that depend on stable international data flows. TeleGeography, a specialist research firm tracking telecom infrastructure, says the Strait of Hormuz carries several active submarine cable systems, including AAE-1, FALCON, Gulf Bridge International Cable System and Tata-TGN Gulf.
The immediate concern is that the Strait of Hormuz and Bab el-Mandeb have become dual choke points for both energy and digital infrastructure. Industry experts say these corridors are critical because they sit on routes linking Asia, Europe and Africa. TeleGeography’s recent analysis indicates that damage inside the Gulf would be particularly difficult to repair if access remains constrained by conflict, mines or active naval threats. That means the danger is not only the initial break, but the possibility that broken systems could remain offline for a prolonged period because cable-repair ships may not safely enter the area.
Red Sea cables and Hormuz subsea cables form a vital digital corridor
The wider network risk becomes more serious because the Red Sea is already a dense corridor for international connectivity. Recent reporting from Rest of World says the Red Sea and the Strait of Hormuz together carry the undersea cable traffic that underpins the Gulf’s growing cloud and artificial intelligence ambitions. The same report cited Kentik internet analyst Doug Madory as saying that simultaneous disruption at both choke points would be a globally disruptive event. That assessment is especially important because the risk is not confined to one country or one cable system. It affects an interconnected mesh of routes that support data centres, financial systems, enterprise traffic and consumer internet services across regions.
There is also a factual point worth clarifying. The most commonly cited count for the Red Sea corridor in recent expert reporting is 17 submarine cables, not 20. That figure appears in recent infrastructure coverage and has become a baseline reference in discussions about Red Sea cables and undersea cable risk. Even so, the exact number matters less than the concentration of capacity moving through a narrow and conflict-exposed maritime zone.
India internet connectivity could face stress even without a total outage
For India, the danger is not necessarily a complete loss of internet access but weaker resilience in overseas connectivity. TeleGeography identifies Tata-TGN Gulf as one of the active systems through the Strait of Hormuz, making India internet connectivity directly relevant to the story. If one or more Gulf routes are damaged, traffic can often be rerouted through alternate systems, but that usually comes with higher latency, reduced redundancy and possible congestion. In practice, that can affect cloud platforms, international payments, enterprise communications, data centre performance and other digital services that rely on fast, stable cross-border links.
This is why experts are framing the issue as global internet disruption risk rather than a simplistic “internet shutdown” scenario. TeleGeography’s Alan Mauldin has argued that Hormuz alone poses limited danger to all Europe-Asia traffic, but he has also stressed that repair operations in a war zone are a major concern. That means undersea cable risk rises sharply when military activity, mines and restricted access make even routine maintenance or emergency response difficult.
Past cable damage shows how fragile digital routes can be
Recent history suggests these fears are not theoretical. Reporting cited across current coverage notes that attacks linked to Houthi activity in the Red Sea damaged multiple subsea cables in 2025, contributing to internet slowdowns in parts of Asia and the Middle East and complicating repairs because access to the damaged zone was restricted. Those incidents demonstrated how vulnerable underwater infrastructure can be when maritime security deteriorates. They also showed that even when the global internet remains functioning, local and regional services can be significantly affected for extended periods.
The expert takeaway is that modern digital systems depend on surprisingly fragile physical infrastructure. Undersea cable risk is often underestimated because most users experience the internet as a cloud-based service rather than a network of physical fibre lines on the seabed. But these cables support banking, healthcare systems, stock exchanges, international logistics, government communications and artificial intelligence workloads. A prolonged interruption in Hormuz subsea cables or Red Sea cables would therefore be felt far beyond ordinary browsing speeds
