The Physical Vulnerability of the Internet_ Iran's Cable Mapping Explained

The internet relies on a physical backbone of undersea fiber optic cables that carry 97% of international data traffic, from emails to video streams. These cables form a vulnerable network, especially in geopolitically tense regions like the Middle East, where Iran's central position exposes its connections to disruption. This episode maps Iran's cable infrastructure, highlighting how its links to neighbors and major routes create both opportunities and risks for global communications.

Iran's Regional Fiber Optic Links

Iran sits at a crossroads for Middle Eastern internet traffic, with fiber optic networks connecting it to Turkey, Iraq, Kuwait, Oman, and other neighbors. These land-based channels support daily data exchange for users and businesses, integrating Iran into the broader regional web. The country's location amplifies its role, as traffic funnels through limited paths, making any break in connectivity propagate widely. While Iran has expanded its domestic fiber network, this setup underscores a dependence on shared infrastructure prone to regional instability.
