Moscow's blackout began on 5 March, starting in outer suburbs before spreading through downtown areas, trapping approximately 13 million residents without mobile internet for a week. During the disruption, many foreign websites were blocked on mobile phones, while online government services, top banks and taxi apps also stopped working.
The chaos was both immediate and absurd. Wildberries recorded a 27 per cent rise in sales of walkie-talkies in early March compared to February, while sales of pagers grew 73 per cent. Road map sales in Moscow surged 170 per cent. Residents who had grown accustomed to digital maps and ride-share apps found themselves navigating streets with paper atlases and communicating via devices that belonged in a Cold War thriller. Even the State Duma, Russia's lower house of parliament, lost internet connectivity in its own building, forcing lawmakers to use landline phones.
The bill to Moscow's economy was staggering. Russian media outlet Kommersant estimated that a five-day shutdown cost the city's businesses between $54 million and $89 million. The disruption was neither uniform nor predictable; some neighborhoods lost service while others maintained connectivity, and residents reported that even "whitelist" services—supposedly essential websites meant to stay online—disappeared in certain districts.
Officially, Russian authorities claimed the restrictions were part of measures to protect against Ukrainian drone attacks. Kremlin spokesperson Dmitry Peskov said the shutdowns were carried out in "strict conformity with the law" and would continue "as long as additional measures to ensure security of our citizens are necessary". Yet the scale and timing of the Moscow disruptions suggest something larger at work.
Since 2019, Russia's "sovereign Internet" law has been in effect—a measure that is expected to ultimately enable the government to monitor electronic information flows in real time, cut off access to content it deems "dangerous," and isolate the Runet as a defence against foreign cyberattacks. The underlying technology relies on deep packet inspection (DPI) technology, which allows the authorities to filter and reroute traffic without the active participation of ISPs.
What Moscow residents experienced last week appears to align with tests of this censorship infrastructure. A source from the Digital Development Ministry told the RBC business daily that the Moscow internet outages were a test of the ability to block access to sites not on the "white list." The whitelist system is designed to allow access only to government-approved websites. During such periods, only websites and services that are on a government-approved list remain accessible.
The concerning element is permanence. The use of whitelists has not only failed to solve the problem of access to internet services during mobile internet blackouts; it has spawned a fear that the authorities will never restore full internet access—even after the end of the war—and that whitelists will end up becoming the new normal. Russian internet analysts note that earlier versions of this infrastructure proved unreliable, but the Kremlin continues refining the system.
This is not merely a Moscow story. In June 2025, there were 655 internet shutdowns recorded in the country, and by July, this figure had risen to 2,099, exceeding the number of shutdowns worldwide for the entire year. Regions across Russia have experienced rotating blackouts since May 2025, initially framed as security measures around Victory Day celebrations.
The technical reality is that Russia's approach differs significantly from China's Great Firewall. The main difference between the "sovereign Runet" and the "Great Firewall" of China lies in their architecture. In Russia, filtering and traffic management systems are installed on the side of telecom operators; but in China, that control technology is situated on its 'border' with the rest of the world. Russian internet experts have warned that this decentralised approach is fragile; filtering systems malfunction regularly, and operators lack a unified command structure.
Still, the Kremlin persists. Efforts have also intensified to replace foreign platforms and online services with domestic equivalents, which are kept under full control of the security services. When foreign websites become unreliable or blocked, Russian government-backed alternatives gain market share by default. The pattern repeats across messaging apps, social networks, and payment systems.
For observers in the Indo-Pacific region, the Moscow blackouts illustrate a broader trend toward digital authoritarianism. Countries in Russia's geopolitical sphere of influence have been importing its SORM tech and replicating its legal framework for surveilling domestic citizens. Aspects of Russia's version of cyber sovereignty are expanding to Brazil, India, and Turkey, where policymakers have been discussing provisions that can enable further crackdowns on free expression, privacy, and other human rights. The infrastructure Moscow is testing becomes an export product—a model for aspiring digital autocrats elsewhere.
The ordinary Moscow resident adapting to offline life, drawing routes on paper and communicating by radio, may not see themselves as part of a larger experiment in state control. But the Kremlin's repeated testing of internet isolation, its steady refinement of censorship equipment, and its replacement of foreign platforms with domestic alternatives paint a picture of deliberate system-building. Whether the blackouts were intended as dry runs for permanent isolation or simply tests of existing infrastructure remains unclear. What is certain is that Moscow's week without the internet revealed both the fragility of modern digital life and the growing capacity of states to disrupt it on demand.
