The Hormuz Digital Chokepoint: How Does the Iran War Threaten Subsea Cables?
The Strait of Hormuz, a narrow waterway between Iran and Oman, is not only a vital passage for oil tankers but also a critical chokepoint for global internet connectivity. A significant portion of the world's subsea fiber-optic cables pass through this region, linking the Middle East, Asia, and Europe. In the event of a conflict with Iran, these cables could be severed or disrupted, causing widespread internet outages and economic damage.
Why Is the Strait of Hormuz Important for Digital Infrastructure?
Subsea cables are the backbone of the internet, carrying over 95% of international data traffic. Several major cable systems traverse the Strait of Hormuz, including the Falcon, SEA-ME-WE-4, and the Gulf Bridge International cables. These cables provide connectivity to countries like the United Arab Emirates, Saudi Arabia, Qatar, and India. The strait's shallow waters and heavy shipping traffic make it a vulnerable point for cable damage.
What Are the Risks of a Conflict?
In a military confrontation, Iran could target or mine the strait, damaging cables directly or indirectly. Anchor drops from naval vessels or sabotage could sever cables, leading to months-long repairs. Such disruptions would impact financial markets, cloud services, and communication networks globally. For instance, a cable cut in the Red Sea in 2020 affected internet speeds in several African countries.
How Can Countries Mitigate the Threat?
Diverse routing is key. New cable projects like the 2Africa and Blue-Raman cables are exploring alternative paths bypassing the strait. Additionally, satellite internet services, such as Starlink, could provide backup connectivity. Governments and telecom companies must invest in redundant infrastructure to ensure resilience. The strategic importance of the Strait of Hormuz as a digital chokepoint underscores the need for international cooperation to protect undersea cables.
As tensions with Iran persist, the vulnerability of global internet infrastructure demands urgent attention. The digital world is more interconnected than ever, and a single chokepoint like Hormuz could bring it to its knees.
