AiBotThe ongoing closure of the Strait of Hormuz since March 2026 has brought to light the vulnerabilities of SpaceX’s Starlink satellite internet network, revealing an unexpected interdependence on ground infrastructure. According to an analysis published by HSToday, the American homeland security-focused outlet, the shutdown has had far-reaching effects on the supply chain, severely disrupting the network’s ability to maintain and expand its operations.
Starlink’s reliance on low-Earth-orbit satellites, comprising over 9,400 units, has often led to the misconception that it operates independently from ground infrastructure. However, the analysis sheds light on key components critical to the network’s functioning, which now face significant disruptions. Helium, cooling gases, and specialized semiconductors – all essential to the network’s operation – are unable to transit through the Strait of Hormuz, leading to a grinding halt in the supply chain.
Each Starlink ground station, comprising massive antennas and heavy equipment weighing several tons, relies on sea-based transportation through the Strait of Hormuz to reach West Asia and Africa. With the Strait closed, no new equipment or spare parts are arriving, forcing the network to suspend critical maintenance and upgrades. The report notes that if the undersea cables, which carry 97% of global internet traffic, were also cut, it would precipitate a ‘no cables, no satellites’ scenario, exposing the interconnectedness of modern global communication systems.
Moreover, Starlink’s reliance on laser links between satellites has been put to the test during recent crises, with the system struggling to manage massive traffic volumes. In instances of extreme traffic, latency has reportedly reached as high as 300 milliseconds, underscoring the network’s limitations. This situation highlights the challenges of scaling up satellite-based communication systems, as they confront the demands of exponential data growth.
While Starlink’s resilience in the face of adversity has garnered praise, this recent episode serves as a timely reminder of the interconnectedness of modern global communication systems. As nations and companies explore new technologies to propel global connectivity, they must also acknowledge the need for redundancy, diversification, and resilience in infrastructure design to mitigate disruptions. By studying this experience, stakeholders can better prepare for the intricacies of modern communication networks and foster more robust systems that can withstand the demands of an increasingly interconnected world.
