How the Iran War Could Threaten Global Internet Access

The latest salvo in the ongoing Iran-US conflict has sparked concerns over global internet access. Iranian lawmakers are proposing an annual fee for tech companies using fiber-optic cables that traverse beneath the Strait of Hormuz, a critical digital artery connecting India, Southeast Asia with Europe.

This move is more than just a technicality; it speaks to a broader struggle for control over global infrastructure. Nations have long taken their digital connectivity for granted, assuming it’s an immutable backdrop against which international relations unfold. However, the Strait of Hormuz is a linchpin in the world’s internet backbone.

Undersea cables are essential to modern global economies, carrying more than 99% of international internet traffic, according to the International Telecommunication Union (ITU). Disruptions here could slow or interrupt internet services worldwide, affecting military communications, financial transactions, cloud computing, and digital services. The stakes are high enough that even a hint of disruption has sent shockwaves through the tech world.

The Iranian government’s plan mirrors its efforts to assert control over shipping through the Strait. In retaliation for US-led airstrikes, Iran effectively closed the waterway to most ships in February, citing the need for safe transit fees after the conflict ends. The timing is telling – just as peace negotiations with the US were gaining traction.

The idea that a single nation could hold the world’s internet hostage may seem far-fetched, but it’s not unprecedented. In 2010, Egypt briefly cut off internet access during widespread protests, crippling global connectivity and prompting comparisons to a “digital blackout.” While that incident was short-lived, its implications were clear: in an era where data transmission is critical to modern economies, any disruption can have far-reaching consequences.

The Strait of Hormuz’s unique geography makes it particularly vulnerable. At just 21 nautical miles wide at its narrowest point, it’s a chokepoint waiting to happen – and the fact that multiple commercial submarine cable systems traverse this critical corridor only amplifies the risk.

Middle Eastern and Asian countries will be disproportionately affected by any disruptions. Gulf states like Qatar, Bahrain, and Kuwait rely heavily on these cables and would face severe operational bottlenecks in the event of damage or disruption. The impact won’t stop there – as more countries increasingly rely on digital infrastructure to underpin their economies, even minor disruptions can have far-reaching consequences.

In an era where cloud services are the norm and data transmission is near-instantaneous, any significant slowdown could send shockwaves through global markets. As tensions simmer in the Middle East, it’s time for nations to confront the elephant in the room: our reliance on digital infrastructure as a fragile, high-stakes system.

We can no longer afford to take this connectivity for granted – or assume that someone else will pick up the slack if disaster strikes. The Strait of Hormuz is more than just a waterway; it’s a stark reminder of our collective vulnerability in the face of global uncertainty.
