March 2026 will be remembered as the month the internet finally splintered beyond repair. In a span of just two weeks, three separate developments across three continents have revealed a new global reality: the open, borderless network that defined the digital age is being systematically dismantled. In Washington, the Federal Communications Commission (FCC) effectively banned foreign-made consumer internet routers, citing national security concerns and a wave of state-sponsored cyberattacks . In Moscow, the Kremlin imposed sweeping mobile internet blackouts across the capital, testing a nationwide censorship system designed to control communications during wartime . And in Tehran, the government entered its 23rd day of near-total internet isolation—over 500 consecutive hours without meaningful connectivity—as the conflict with the United States and Israel escalated .
Taken together, these events signal the end of an era. The internet is no longer a single, unified space. It is becoming a collection of digital territories—each with its own borders, its own gatekeepers, and its own rules about who can connect, what they can see, and how they can communicate.
The American Wall: Foreign-Made Routers Banned
On March 23, the Federal Communications Commission delivered a seismic shift in U.S. internet policy, adding all consumer-grade routers made outside the United States to a list of equipment deemed a national security risk . The ban, which takes effect immediately, prohibits the import, marketing, or sale of any new foreign-made router models. Americans can continue using routers they already own, but the market for new devices has been fundamentally restructured.
The FCC’s justification was stark. “Malicious actors have exploited security gaps in foreign-made routers to attack American households, disrupt networks, enable espionage, and facilitate intellectual property theft,” the commission said in its announcement . The decision follows years of growing concern over router vulnerabilities, which were implicated in three major cyberattacks—dubbed Volt, Flax, and Salt Typhoon—targeting U.S. infrastructure between 2024 and 2025. U.S. government investigations attributed those attacks to actors working on behalf of the Chinese government.
The ban applies even to routers designed in the U.S. but manufactured abroad—a category that includes virtually every major brand except Starlink, whose routers are made in Texas . Companies seeking to import foreign-made routers can still apply for conditional approval, but only if they disclose foreign investors and commit to eventually moving manufacturing to the United States. The message from Washington is unmistakable: the infrastructure of the American internet must be American-made.
The Russian Model: Moscow Goes Dark
Half a world away, Russia is pursuing a different vision of digital sovereignty—one built on control rather than self-reliance. Since early March, mobile internet in central Moscow has been completely down for hours at a time, with connectivity disappearing entirely during peak hours . The outages, which began affecting Russia’s regions in May 2025, now impact approximately 146 million people nationwide. In Moscow alone, the disruption has paralyzed daily life: office workers without connectivity, taxi drivers unable to navigate, teenagers cycling through increasingly scarce VPNs to reach blocked services.
The Kremlin has defended the shutdowns as necessary security measures against Ukrainian drone attacks, which can use cellular networks for navigation. “These measures are taking place,” Kremlin spokesman Dmitry Peskov said when asked about the restrictions. “They are partly related to the fact that a number of foreign companies refuse to comply with the norms of Russian legislation, and partly due to security measures against the threat of Ukrainian drones” .
But analysts and diplomats see a deeper agenda. New laws now oblige mobile operators to cut off any client at the demand of the Federal Security Service (FSB), giving the agency sweeping powers to control connectivity at will . Andrei Soldatov, a Russian investigative journalist and expert on the security services, told Reuters that Moscow has studied the experiences of China and Iran and is now building a system that can block swathes of the internet while controlling online communications. “What is happening now is that the security services are trying to create a situation in which—if Putin signs a peace deal or if Putin goes for a protracted war—it would not destroy the whole thing” .
The human toll is already visible. In suburban Moscow, a mother named Svetlana relies on continuous internet to monitor the blood sugar levels of her diabetic eight-year-old son, using Telegram to send insulin dosage instructions. Last month, Telegram was blocked entirely. “This internet restriction seems so illogical,” she told CNN. “For decades, we were told that the internet and digitalization were so cool and so important. And then suddenly, everything we had built, everything we had been encouraged to rely on, is restricted” .
The Iranian Siege: 528 Hours and Counting
If Russia is testing a system of selective control, Iran has entered the realm of total isolation. According to NetBlocks, the international internet monitoring service, Iran has been under near-total internet blackout for over 500 hours—22 days and counting—since the outbreak of hostilities with the United States and Israel on February 28 .
“After 528 hours, Iran is entering a 23rd day isolated from the world as the regime-imposed internet blackout continues in its fourth week,” NetBlocks said in a statement on X . Iranian Foreign Minister Abbas Araghchi acknowledged the restrictions earlier this month, stating that the internet is limited “for security reasons, since the state is subjected to aggression and is obliged to protect the people” .
The shutdown has been nearly total. For three weeks, Iranians have been cut off from the global internet, with only a privileged few—government officials, Revolutionary Guard personnel, and pro-regime media—maintaining connectivity through “white SIM cards” exempt from the filtering system. The regime’s approach represents a new form of digital authoritarianism: total isolation for the general population, selective access for those who can “better deliver the message” .
For ordinary Iranians, the consequences have been devastating. Without access to global news, social media, or encrypted messaging apps, citizens have been left in the dark about the conflict unfolding around them. When reports emerged this weekend of a strike on a building linked to the sanctioned Iranian electronics firm Sairan in central Tehran, residents struggled to verify the information or communicate with loved ones . In a country where the economy had already been battered by sanctions, the internet blackout has paralyzed businesses, cut off remittances from the diaspora, and left families scrambling for any means of communication.
The Infrastructure Reality: Subsea Cables and Supply Chains
Beneath these headline-grabbing developments, a more subtle crisis is unfolding in the physical infrastructure of the internet. The Strait of Hormuz, already a chokepoint for global oil supplies, is also a critical passage for subsea cables linking Asia, Europe, and Africa. The conflict has disrupted multiple cable projects, including Meta’s massive 2Africa system—a 45,000-kilometer network that will be the world’s largest fiber-optic cable when completed . Alcatel Submarine Networks, the French state-owned company laying the cable, has sent force majeure notices to customers, and its installation ship remains stranded off Saudi Arabia.
The impact on repairs is equally concerning. Cable ships are not operating in areas with active military operations, meaning that if existing cables are damaged—whether by ship anchors, underwater explosions, or accidents in crowded waterways—fixing them could take weeks or months. For the average user, experts warn that the result will likely be widespread slowdowns rather than total blackouts, as traffic spills into congested alternative routes . Streaming quality may drop. Gaming latency could spike. And the invisible infrastructure that powers global finance, communication, and commerce will become visibly fragile.
The Outlook: A Contested Future
As March 2026 draws to a close, the internet stands at a crossroads. In the United States, the response to perceived threats has been to build walls—to secure the network by controlling the hardware that connects to it. In Russia, the response has been to build levers—to create a system that can be switched on and off at the government’s discretion. In Iran, the response has been to build a cage—to isolate the population entirely, preserving connectivity only for those loyal to the regime.
Each model reflects a different vision of what the internet should be. But together, they reveal a common trajectory: the end of the unified, borderless network that defined the digital age. The internet of 2026 is not the internet of 2016. It is more contested, more fragile, and more fragmented. For users in Moscow, Tehran, and beyond, the question is no longer whether they can connect, but what version of the internet they will be allowed to see.
As one analyst put it: “The infrastructure of the digital world is no longer invisible. For the first time, we are being forced to see it for what it is: a system that can be broken, a tool that can be weaponized, and a space that must be defended” .
