Could Iran Cut the Global Internet with Cables in the Strait of Hormuz?

The escalating conflict between Iran and the West, coupled with instability in the Red Sea, is creating a dangerous 'double chokepoint' for the global network of submarine fiber optic cables, which carry 99% of the world's internet traffic. Approximately 600 cables, extending over 1.5 million kilometers, lie on the ocean floor and are not designed for wartime conditions, making them vulnerable to damage. The Persian Gulf and Red Sea region, where at least 17 major cables pass, has become a 'high-risk zone' due to mine laying and attacks. Attacks in the Red Sea have already caused internet slowdowns, while access for repairs is limited. The situation has led to the suspension of infrastructure projects, such as the 2Africa Pearls cable system, and raises concerns about the economic impact of a disruption to global connectivity. The lack of protection for these critical infrastructures, combined with increasing geopolitical tensions, creates an unprecedented challenge for digital security.
