Iran is About to Cut Ties With the Global Internet

Twenty-five days and counting. That's how long Iran kept 90 million people in digital darkness ever since the beginning of January. The government shut down the entire internet as protests erupted across the country, severing not just connections to the outside world but even Iran's own domestic network.

Hospitals ran out of blood, the economy bled $35 million per day, and under that blanket of silence, security forces killed what some estimate to be up to 30,000 protesters. And the worst of it? All of this was just a dress rehearsal for what’s to come.

What Iran's actually building is way more permanent than a temporary shutdown. The National Information Network, or NIN for short (no, sadly it’s not the Nine Inch Nails), isn't your standard censorship system where the government blocks websites and you fire up a VPN to get around it. This is something a lot more like what North Korea's been running for decades.

A walled garden where the entire country gets cut off from the global internet, and only a select few with special permissions can peek outside, is pretty much already covering Iran. Calling this situation dire would be an understatement. 

What Iran is Actually Building

The National Information Network started as an idea way back in 2005. Iran's government called it the "halal internet" at first, framing it as a way to protect citizens from immoral Western content. That marketing didn't stick, so they rebranded it as the NIN. But the goal never changed: total control over what Iranians can see, say, and share online.

Over the past two decades, Iran's dumped more than $6 billion into building this thing. They've laid fiber optic cables, set up domestic data centers, and created Iranian alternatives to YouTube, Amazon, and messaging apps. The infrastructure is all there and what happened now was just the flip of the switch.

The NIN operates as a domestic intranet, like a giant corporate network but for an entire country. All internet traffic routes through government-controlled gateways, which means authorities can see everything, block anything, and most critically, separate domestic traffic from international traffic.

We’ve already seen examples of this when, during the recent shutdown, Iranian authorities kept IPv4 routes online while disrupting IPv6 traffic. By maintaining those routes, they could selectively grant internet access to specific users while denying it to everyone else.

That's where whitelisting comes in. Instead of blocking bad sites (blacklisting), Iran is moving to a system where they only allow access to approved sites. Everything else? Blocked by default. According to digital rights group Filterwatch, Iran has already deployed Deep Packet Inspection updates specifically designed to fingerprint and block VPN traffic.

The system includes tiered access. Regular Iranians get the domestic internet only: government-approved news sites, state-run social media alternatives, and banking services that stay within Iran's borders. Then there's a privileged class, including government officials, academics on special lists, and certain businesses, who get broader access through state-issued VPNs.

But even those “privileged” users aren’t exactly free to act as they please. For example, at the moment, members of the Chamber of Commerce in certain cities are granted around 20-30 minutes of unfiltered internet access per day. Sounds bad? Well, it gets even worse, because this only happens after several stages of identity verification and only under the physical supervision of security or intelligence agents.

North Korea has been running a similar setup called Kwangmyong since 2000. It's an intranet with maybe a few thousand websites, all government-approved. Most North Koreans have never seen the actual internet. Iran's version will be bigger and more sophisticated, but the principle's the same: build a digital prison and call it national security.

Why This Matters More Than Regular Censorship

There's a massive difference between censorship and isolation. Censorship blocks specific content. You can work around it, fight it, and expose it. Isolation cuts the connection entirely. It's the difference between living in a country with strict press laws and living in a country where newspapers practically don't exist.

For Iran's researchers and scientists, this is catastrophic. According to Science Magazine, Iranian universities have already been asked to provide lists of academics who'll get special internet access. That means collaboration with foreign researchers becomes impossible for everyone else. Peer review? Forget it. Access to international journals? Only if you make the government's approved list and accept that they're watching everything you read.

The economic damage is staggering. During just the recent blackout, online sales dropped 80%, and the Tehran Stock Exchange lost 450,000 points in four days. One hundred thirty trillion Iranian tomans evaporated daily. Now imagine that becoming the new normal, where international commerce requires special permissions and every transaction leaves a government-readable trail.

But the human cost is what really matters. Internet shutdowns don't just inconvenience people but are also a perfect cover-up for violence. During these past twenty-five days, the world got fragments of information about massacres, hospitals overwhelmed with gunshot victims, and bodies piled up at forensic centers. We got those fragments because a tiny percentage of people managed to connect through Starlink or cellular networks from neighboring countries. And yet, there undoubtedly is plenty more of that we don’t know about.

The NIN makes that darkness permanent. Forget about emergency Starlink connections or clever VPN workarounds. It will be a population cut off from the world while their government does whatever it wants behind a digital wall.

When Walls Get Higher, Freedom Gets Smaller

Iran's not doing this in a vacuum. Russia's watching closely and reportedly moving toward its own whitelisting system. They've been building their domestic internet, the Runet, for years. Now they're taking notes from Iran's playbook about how to make the transition from heavy censorship to total isolation.

This is how it spreads. China already exports its Great Firewall technology to countries like Ethiopia, Myanmar, and Kazakhstan. Iran's NIN project had Chinese technical assistance in developing its infrastructure and surveillance algorithms. Now Iran's pioneering the next dystopian evolution.

The implications go way beyond Iran, too. The technology's getting cheaper, while the infrastructure is becoming more standardized. Every successful implementation of total digital isolation makes it easier for the next country to try it, and dictatorships are excellent at learning from each other.

What makes this especially dangerous is that it works. North Korea has kept its population in digital isolation for decades. China's Great Firewall, while not complete isolation, has proven that a government can effectively control what 1.4 billion people see online. But now, Iran's demonstrating that even a country integrated into global trade and dealing with international sanctions can still cut its population off from the world when it wants to.

Iran is planning to fully enforce this system by March 2026 at the latest. Ninety million people are about to be cut off from the world, maybe permanently. And for the rest of us, it’s a warning.

The open internet, the one we've been using since the 1990s, is, unfortunately, dying. It's being replaced by nationalized internets, digital territories with hard borders where governments control not just what you can say but what you can see and who you can talk to. Iran’s situation may seem distant right now, but don’t get fooled, because it’s a lot closer to home than it appears.
