Starlink Under Control: How Ukraine’s White List Disrupted Russian Military Communications
On February 5, Ukraine’s Minister of Defense Mykhailo Fedorov announced the launch of a full-scale “white list” mechanism for Starlink satellite internet terminals. Verified and registered devices are operating, while terminals used by Russian forces have been blocked. This information was confirmed not only by Ukrainian officials but also by Russian Z-channels and so-called “war correspondents,” who openly spoke of large-scale disruptions and a loss of military command and control.
Time for Action analyzed what exactly happened, why the effect proved so abrupt, and what consequences this decision has for both sides of the war.
In January 2026, confirmed reports began to emerge that the Russian army was using Starlink terminals to control long-range drones during strikes against Ukraine. These were not isolated cases but a serial solution. Russian drones equipped with satellite communications are difficult to intercept or suppress with electronic warfare; they fly at low altitudes and are controlled by operators in real time over long distances. The Ukrainian side chose not a path of selective bans but a systemic approach. The key element was coordination with SpaceX and a move toward authorizing every terminal. The decision was formalized by a government resolution on February 2. From that point on, only verified and registered devices are allowed to operate in Ukraine; everything else is subject to disconnection.
According to Mykhailo Fedorov, the first batch of terminals included in the “white list” is already functioning. The lists are updated once a day. This means the system is not a one-off measure but a continuous access filter. Civilian users must verify their Starlink terminals through administrative service centers. For legal entities, a corresponding service is expected to become available on the Diia portal. The Ministry of Defense emphasizes that the process is large-scale and requires time, while real-time verification is still under development. Particular emphasis is placed on the continuity of communications for the front. That is why military units and commanders were involved in the rapid submission of data for verification.
The Russian response: from disruptions to “catastrophe”
The most telling indicator of the decision’s effectiveness was the reaction of the Russian information space. Pro-war channels almost simultaneously reported mass Starlink outages. Their posts described the loss of internet not only for drone crews but also for infantry units, electronic reconnaissance assets, and firing positions. Radio technology expert and adviser to Ukraine’s Minister of Defense Serhii “Flash” Beskrestnov described the situation for the adversary as catastrophic. According to him, assault operations halted in many sectors of the front. At the same time, he noted that on the Ukrainian side, problems arose among those who failed to promptly submit lists for private Starlink terminals. Russian channels openly acknowledge the lack of a full-fledged alternative to SpaceX’s satellite communications. Their messages include calls to urgently find technical solutions and promises to refund money for “Starlinks” purchased through public fundraising campaigns in Russia.
The disconnections affected not only the military. In occupied cities, including Sievierodonetsk, residents are mass-complaining about the complete loss of satellite internet. In regions where other communication channels have been blocked or destroyed, Starlink had effectively remained the only way to access the internet. Its disappearance created an information vacuum whose causes local residents do not understand. This aspect highlights another dimension of the decision: technical restrictions aimed at military infrastructure inevitably affect civilian populations in occupied territories as well.
The Ukrainian front: a transition period and mounting strain
Ukrainian military personnel also reported temporary disruptions. Most often, this concerned terminals purchased with personal funds during the period of volunteer units and not entered into state registries. The registration procedure proved new not only for service members but also for administrative service center staff, which further complicated the first days of implementation. This situation exposed a structural problem that had accumulated over years: a significant portion of frontline communications was built through volunteer and private efforts. The shift toward centralized control requires rapidly bringing order to this system without allowing prolonged communication gaps.
Blocking unregistered Starlink terminals for Russian forces is not merely about internet access. It involves the loss of the ability to coordinate units, control long-range drones, and maintain stable command and control. On February 1, SpaceX CEO Elon Musk stated that the measures taken by his company to stop Russia’s unauthorized use of Starlink appeared to have produced results. The events of February 5 became a practical confirmation of that assessment.
The introduction of the “white list” demonstrated that administrative and technical decisions can have a direct and rapid impact on the conduct of hostilities. Ukraine managed to shut down a channel the adversary had come to rely on, without deploying additional military means. At the same time, the situation also highlighted Ukraine’s own vulnerabilities: dependence on private infrastructure and the difficulty of swiftly transitioning to a fully controlled system. The coming weeks will test whether communications for Ukrainian forces can be stabilized without losing momentum and whether the adversary will be able to find alternatives to compensate for the loss of Starlink.
