Russian units fighting in Ukraine have been abruptly severed from the Starlink satellite network they had quietly come to depend on for battlefield communications. Elon Musk ordered Russian army-linked terminals in occupied territory cut off, a move Ukrainian officials describe as a serious blow to Kremlin forces’ ability to coordinate along the front.
The blackout has exposed how deeply both armies had woven commercial space internet into their daily operations, and how much power now rests with a single private company. It has also triggered a new round of debate over whether one tech billionaire should be able to tilt the balance of a major war with a software update.
How Russia ended up relying on Starlink in a war built on it
From the first months of the full-scale invasion, Ukraine treated Starlink as a lifeline, using tens of thousands of terminals to keep artillery crews, drone operators and field commanders online when fiber lines and cell towers were destroyed. Over time, Russian units on the other side of the trenches began acquiring their own terminals through gray markets and intermediaries, turning the same low-orbit constellation into a tool for their own command-and-control. Ukrainian officials now say that Russian-operated devices inside Ukraine have been identified and cut off, leaving those units suddenly offline along key stretches of the front, a disruption they link directly to the decision to disable Russian Starlink access in occupied areas.
Advisers to the Ukrainian defense ministry describe the impact in stark terms, saying the shutdown has had a serious effect on Russian operations, with some claiming that command-and-control links have been broken and that units are reverting to couriers carrying memory sticks between positions. Those advisers argue that the Russian army had grown dependent on the same commercial network that underpins much of Ukraine’s own battlefield connectivity, and that the sudden loss of service is forcing Russian commanders to fall back on less secure and slower systems. Their assessment is echoed in Ukrainian reports that frontline Russian formations are now struggling to maintain stable links after their Russian terminals went dark.
Musk’s “unauthorized use” crackdown and the technical cut-off
Elon Musk has framed the move as a response to what he calls “unauthorized” Russian use of Starlink, insisting that his company never sold service to the Russian state and that any military access was obtained through back channels. He has said that SpaceX is taking steps to stop Russia of using the Starlin network without permission, describing on Sunday how the company is tightening controls so that terminals registered to Ukraine remain active while those linked to Russian forces are excluded. In his telling, the company is trying to balance support for Kyiv’s military, which relies on tens of thousands of devices, with a refusal to provide connectivity to an army operating under Western sanctions, a stance he has reiterated in public comments about Starlin access.
Earlier this year, Musk also said that SpaceX had successfully cut off the Russian military link to its satellites, presenting the change as a targeted technical intervention rather than a blanket shutdown. He described how the company can identify traffic patterns and device registrations associated with Russian units and then revoke their ability to connect, while keeping Ukrainian accounts whitelisted. That approach, he suggested, allows SpaceX to surgically deactivate only Russian units without harming Ukraine’s own connectivity, a claim that aligns with reports that the company has moved to block Russian military access while keeping Ukrainian networks intact.
On the ground: a communications shock for Kremlin troops
For Russian soldiers at the front, the change has been felt less as a policy shift and more as a sudden blackout. Ukrainian officials say Russian troops on the front lines have lost access to Starlink internet terminals, reporting that units which had been using the system for encrypted chats, drone feeds and logistics are now cut off. They argue that this has created a serious disruption in Russian command chains, with some positions reportedly unable to reach higher headquarters except through vulnerable radio channels after their Starlink internet links were severed.
Ukrainian defense officials say the effect is visible in intercepted communications and battlefield behavior, with Russian units reportedly taking longer to respond to attacks and struggling to coordinate artillery and drone strikes. Advisers to the ministry say the shutdown has had a serious impact on Russian operations, describing it as a blow that compounds existing logistical and morale problems. They also stress that Ukrainian forces remain online, since their own terminals are registered and approved, while Russian devices are being blocked unless they are re-registered in jurisdictions that comply with restrictions on equipment used in Russia under U.S. sanctions.
Ukraine’s advantage and Moscow’s scramble for alternatives
Ukrainian officials and analysts say the outage has tilted the communications balance in Kyiv’s favor, at least temporarily. They argue that Russian forces are now facing a “catastrophe” along parts of the front line, with units deprived of the vital satellite services they had come to rely on for everything from drone reconnaissance to basic messaging. Reports from the region describe Russian formations that are cut off from vital Starlink satellites and forced to fall back on older systems, a shift that Ukrainian commanders believe will slow Russian decision making and blunt the effectiveness of its Russian forces.
At the same time, Ukrainian officials caution that Moscow is already searching for workarounds, including attempts to re-register terminals abroad or switch to other satellite providers. They note that some Russian units may eventually restore connectivity after registering their terminals in countries that are not enforcing the same restrictions, which is why Kyiv is pushing Western partners to tighten export controls and monitoring. Ukrainian voices also point to broader geopolitical stakes, with one Polish PM warning that Russia is facing a wider “catastrophe” as sanctions and technology denials erode its military capabilities, even as separate allegations swirl about Epstein and a Russian honeytrap aimed at Americans and public comments from Melania Trump about talks with Americans and the conflict.
Russian pro-war bloggers, Ukrainian officials and the information battle
Even as Ukrainian officials celebrate the disruption, Russian pro-war bloggers have been forced to acknowledge the outage, turning it into a new front in the information war. One pro-Kremlin military blogger, Boris Rozhin, wrote a Q&A-style post on Telegram, conceding that the loss of service would have a certain impact on Russian units but insisting that they would adapt and that everything is fine. His comments reflect a broader effort by Kremlin-aligned voices to reassure their audience that the army can cope without Starlink, even as they confirm that the blackout is real and affecting One Kremlin aligned commentator’s followers.
Other pro-war commentators have reported Starlink outages on the Ukrainian front line, describing how Russian troops suddenly lost connectivity and were forced to switch to less capable systems. Their posts, amplified across social media, have become a rare public confirmation from the Russian side that the network disruption is biting, even as they call on supporters to back the war effort and Support The Moscow Times style appeals to Support The Moscow and other outlets sympathetic to their cause. These accounts, which describe a War Bloggers Report Starlink Outage on the Ukrainian Front Line, underline how the communications blackout has become both a tactical problem and a propaganda issue for Pro War voices.
