March 2026 will be remembered as the month when the vision of a single, borderless internet finally died. Across three continents, events have converged to reveal a new digital reality: one where governments control connectivity as a weapon of state, where infrastructure fragmentation threatens the network’s underlying architecture, and where the ability to access information depends increasingly on where you live—and who governs you. From Russia’s systematic dismantling of independent online communication to Iran’s selective connectivity for regime loyalists, and from the European Union’s push for digital sovereignty to the technical exhaustion of the internet’s foundational protocols, the forces reshaping the global network have never been more visible—or more consequential.
The Russian Model: Cutting Off the Capital
In Russia, the intensification of internet censorship has reached unprecedented levels. Since early March, authorities have imposed sweeping mobile internet restrictions across Moscow and the surrounding region, with connectivity in the capital’s center rendered almost non-existent and access in other districts limited to government-approved websites . The shutdowns, which began in May 2025, have now affected approximately 146 million people nationwide.
The official explanation from the Kremlin is Ukrainian drone attacks. On March 10, Kremlin spokesman Dmitry Peskov attributed the outages to «the primary need to ensure security» . But analysts dismiss this justification. «It’s a general drive to restrict all forms of communication and access to independent information, and to establish control over any communication,» Russian columnist Sergei Parkhomenko told the Kyiv Independent. «Any communication is dangerous for a totalitarian regime during wartime» .
The technical architecture of these controls is becoming clear. Authorities are testing «white lists»—government-approved sites that remain accessible during shutdowns—on a district-by-district basis. According to Leonid Iuldashev from eQualitie, a Canadian IT company that develops tools for circumventing censorship, the implementation has been chaotic: «They are checking if they can turn them on for a particular house, for a particular district, for a particular street, and what the collateral damage would be» .
The crackdown extends beyond shutdowns to messaging apps. In August 2025, Russia began blocking calls on Telegram and WhatsApp, though text messaging remained available. In February 2026, authorities started fully blocking Telegram. By mid-March, roughly 80 percent of requests to Telegram domains failed on average across Russia, with some regions seeing failure rates as high as 90 percent .
Parallel to these restrictions, the Russian government is promoting its domestic alternative: the Max messaging app, which has become mandatory on all new electronic devices. The app gathers and retains user metadata—IP addresses, contact lists, activity logs—and its privacy policy permits sharing this information with government agencies .
The Iranian Approach: Selective Access and the Rise of White SIM Cards
If Russia represents a model of total shutdown, Iran has refined a more nuanced approach: selective connectivity. Since the start of the US-Israeli war on Iran, the country has experienced a near-total internet blackout for 20 consecutive days, with connectivity dropping to less than one percent according to NetBlocks, a group that monitors internet access worldwide .
But the shutdown is not universal. The Iranian government has acknowledged providing special internet access to select users capable of promoting its messaging online. Spokeswoman Fatemeh Mohajerani told reporters that Tehran is offering connectivity to «those who can better deliver the message» . Much of this privileged access operates through so-called «white SIM cards»—mobile lines exempt from Iran’s filtering system that allow direct access to blocked platforms such as X, Telegram, and Instagram .
The selective nature of the shutdown represents a form of digital authoritarianism that maintains connectivity for regime loyalists while silencing dissent. NetBlocks noted that «the regime continues to promote its agenda through whitelisted networks, cultivating media assets at home and abroad» . This stands in stark contrast to President Masoud Pezeshkian’s campaign promises to lift filtering—pledges that remain unfulfilled as the shutdown extends into its fourth week.
For ordinary Iranians, accessing the internet has become a dangerous and expensive black market transaction. Users purchase VPN configurations from sellers on Telegram, routing their traffic through servers outside Iran using tools like OpenVPN or V2Ray . Prices have skyrocketed—one user reported paying 50 million rials (approximately $45) for a one-week package, up from 10 million rials just weeks earlier .
The risks are significant. Users report receiving text messages from security agencies warning that they have been detected connecting to the global internet, threatening consequences if they continue. Sellers have become increasingly cautious, preferring to deal only with known contacts . As one seller explained, «This is no longer just about selling VPNs. It has become a security issue» .
The EU’s Counter-Vision: Digital Sovereignty Through Regulation
While Russia and Iran tighten control through shutdowns, the European Union is pursuing a different path to digital sovereignty: regulatory integration. The proposed Digital Networks Act (DNA), unveiled by the European Commission on January 21, 2026, represents the most ambitious overhaul of EU telecom rules in a generation .
The DNA aims to dismantle what officials call the «fragmentation penalty»—the barrier that prevents European telecom operators, which average just 5 million customers each, from achieving the scale necessary to compete with US and Chinese giants . The legislation would replace 27 national regulatory silos with a unified framework, introducing a «single passport» authorization system allowing providers to operate across all member states under one regulatory approval .
Key provisions include:
- Harmonized spectrum management with extended license durations
- An EU-level framework for satellite spectrum
- Mandatory national plans to phase out copper networks by 2035
- Clarified net neutrality rules supporting innovative services
The resilience dimension of the DNA is equally significant. In the wake of geopolitical disruptions, the proposal includes a «Union Preparedness Plan for Digital Infrastructures» that goes beyond traditional cybersecurity to address hybrid threats . This includes cellular sensing capabilities to detect drones and prioritize the transition to post-quantum cryptography .
Henna Virkkunen, the European Commission’s executive vice president for technology sovereignty, framed the legislation as essential to Europe’s strategic autonomy: «The new framework aims to align authorization regimes and spectrum assignments to accelerate investment in next-generation fixed, mobile, and satellite infrastructure» .
The Technical Fragmentation: Peak IPv4 and the Protocol Crisis
Beneath these geopolitical developments, a technical fragmentation is unfolding that could fracture the internet at an even deeper level. According to Geoff Huston, Chief Scientist at APNIC, the internet has likely passed «peak IPv4″—the point at which the IPv4 network stops growing and begins to contract .
The evidence is clear. IPv4 address prices have begun to decline after years of steady increases. The number of IPv4 routes is no longer rising. And the efficiency of IPv4 use has stopped increasing and started to decline . Huston’s analysis suggests that the IPv4 network may begin contracting as early as 2026, with negative growth inevitable in the years ahead .
The implications are profound. As Huston notes, the IPv4 network still functions, but it is holding back innovation, openness, and diversification. The market has concentrated around a small number of very large players who are inherently risk-averse, conservative, and controlling. There is a danger that the existing internet will disintegrate .
The transition to IPv6 has been sluggish. While IPv6 users now account for 45 percent of Google visitors, adoption is increasing by only about 5 percentage points annually . This slow transition means the internet may remain in a degraded state for years to come—one where many users are behind Carrier-Grade Network Address Translation (CGNAT) structures that make them unreachable from the outside world, breaking applications that depend on peer-to-peer connections.
Conclusion: The End of the Borderless Internet
March 2026 has made clear what has been building for years: the internet is no longer a single, unified network. It is a collection of digital territories, each governed by different rules, different access regimes, and different philosophies of connectivity.
Russia is building a network that can be switched off at will, where communication flows only through state-approved channels. Iran has refined selective connectivity, maintaining access for loyalists while isolating the general population. The European Union is constructing a regulated digital sphere designed for strategic autonomy and resilience. And beneath it all, the technical exhaustion of IPv4 threatens the architecture that has held the network together for decades.
The implications for users, businesses, and societies are profound. The assumption of universal connectivity—the idea that anyone with an internet connection can access the same global network—no longer holds. The splinternet is here. The question for the coming years is not whether the internet will remain unified—it will not—but what forms its fragmentation will take, and who will be able to navigate them.
