The idea of Iran cutting undersea internet cables is often mentioned in geopolitical discussions, but the reality is more complex. Here’s another way to look at it:
🌐 Why undersea cables matter
Around 95–97% of global internet traffic travels through submarine fiber-optic cables lying on the seabed. These cables carry almost everything online—banking data, government communications, financial trading, and everyday internet traffic.
📍 If cables in the Gulf or Red Sea were damaged
If several cables in that region were cut, the impact would likely include:
1️⃣ Regional connectivity problems
Countries around the Gulf—such as Kuwait, Qatar, Bahrain, Saudi Arabia, the UAE, Iraq, and parts of Iran—could experience severe internet slowdowns or temporary outages.
2️⃣ Financial disruptions
Cities like Dubai are major financial hubs. Slower connectivity could affect banking transactions, international payments, and trading systems that rely on ultra-fast internet connections.
3️⃣ Wider ripple effects
Internet routes between Europe, Asia, and parts of Africa pass through the Red Sea and the Persian Gulf, so disruptions there could cause slower internet speeds or rerouting of traffic across other cables.
🛠️ Repairing submarine cables
Fixing a damaged cable usually involves specialized ships that locate the break, pull the cable up from the seabed, repair it, and place it back underwater. Depending on depth, weather, and access, repairs can take several days to a few weeks.
⚠️ Would the world lose the internet?
A complete global blackout is unlikely because:
Most regions are connected through multiple cable routes
Data can often be rerouted automatically
Satellite systems provide limited backup communication
So the impact would probably be regional disruption and slower connectivity, not the collapse of the entire internet.
₿ Crypto impact
If a region temporarily lost internet access, people there might not be able to access exchanges or wallets. However, the Bitcoin network itself would continue running globally through nodes in other countries.
✅ In short: damaging a few cables could create serious regional disruptions and financial delays, but a worldwide internet shutdown would be extremely difficult.
