The story being told about Iran’s war on tech infrastructure focuses on data centers and cloud outages. That story is real — but incomplete. The deeper, slower, more structurally damaging dimension of this conflict is what is happening to the physical cables, shipping lanes, and logistics corridors that carry the internet itself. More than 3,000 drones and missiles have been fired on the United Arab Emirates, Saudi Arabia, Bahrain and Kuwait since the conflict began. CNBC Every one of those strikes carries a tail risk for the physical infrastructure of the global internet.
The Strait of Hormuz Is Also an Internet Chokepoint
Through these waters pass an estimated 30,000 vessels per year. They carry not only a fifth of the world’s seaborne oil and liquefied natural gas but also the urea needed for fertilizers, the aluminium for infrastructure, the helium that cools its semiconductors, and the petrochemicals that form modern supply chains.

A total of 17 submarine cables pass through the Red Sea, carrying most of the data traffic between Europe, Asia, and Africa. With Iran’s closure of the Strait of Hormuz and renewed Houthi threats in the Red Sea, both critical data chokepoints are simultaneously in active conflict zones. The Interpreter
The Submarine Cable Risk Map
| Cable System | Route | Traffic Carried | Current Risk |
|---|---|---|---|
| AAE-1 | Asia–Africa–Europe | Major Europe-Asia backbone | Red Sea conflict zone |
| SEA-ME-WE 5 & 6 | Southeast Asia–Europe | Intercontinental backbone | Active risk zone |
| Tata TGN Gulf | Gulf regional | GCC regional internet | Within strike range |

What Happens If a Major Cable Gets Cut
Unlike a data center outage — which affects one cloud region — a submarine cable cut degrades global internet performance simultaneously across multiple continents:
- Latency spikes for all traffic between Europe and Asia rerouted around the Cape of Good Hope
- Bandwidth bottlenecks as surviving cables absorb redirected traffic loads they were not designed to carry
- Cloud service degradation as cross-region replication slows, affecting disaster recovery systems globally
- Financial market disruption as low-latency trading connections between Asian and European exchanges degrade
The Air Freight Collapse Nobody Is Watching
Air cargo hubs in the Gulf region play a major role in semiconductor wafer transportation. Any sustained disruption could slow chip distribution even if production remains stable. Air freight capacity at Gulf hubs would begin recovering, but with Abu Dhabi at 66%, Dubai at 50%, and Doha at only 17% of pre-conflict levels as of late March, meaningful recovery to normal routing would take weeks to months even in an optimistic scenario.

Semiconductor wafers do not travel by container ship. They travel by air — through Dubai, Abu Dhabi, and Doha. Those three hubs are now operating at a fraction of their normal capacity.
The Recovery Timeline If a Ceasefire Happened Tomorrow
Mine clearance of the Strait of Hormuz under a cooperative ceasefire scenario could enable limited, escorted commercial transit within three to four weeks, though historical precedent suggests at least seven weeks for comparable operations. The backlog of approximately 1,900 stranded ships — half carrying oil, LNG, or chemicals — could begin clearing within days to weeks of reopening, but naval patrol requirements would constrain throughput well below pre-war levels. Tim Harper
The internet's physical infrastructure does not have a fast-reboot option. The cables are on the ocean floor. The ships are anchored in open water. The helium plant in Qatar needs three to five years of repairs. Every week the conflict continues adds months to the recovery timeline for tech supply chains that were already running at maximum tension before the first missile was fired.
