Ukraine Says Overnight Starlink Speed Limits Hobbled Battlefield Missions as Zelensky Aide Points to Political Motives

Newly imposed restrictions on the speed at which Ukrainian military assets can remain connected to Elon Musk's Starlink satellite internet network have disrupted battlefield operations, according to an adviser to President Volodymyr Zelensky. Serhiy Beskrestnov said the limits, which were introduced overnight, took Kyiv by surprise because no prior notification was given to Ukrainian authorities.

The restriction reportedly caps connectivity at 100mph (160km/h), meaning terminals lose their link once a vehicle or weapons platform exceeds that threshold. Beskrestnov said the change had already interrupted "a number of missions," warning that the timing "cannot be a coincidence and is related to the current political situation." SpaceX, the company founded by Musk that operates Starlink, has not responded to requests for comment.

Starlink has become an indispensable tool for Ukraine's armed forces since Russia's full-scale invasion in 2022. Its low-latency satellite connections allow troops to guide drones toward Russian targets, relay signals along the front line, and coordinate air defence efforts aimed at protecting Ukrainian cities from missile and drone attacks.

A source within Ukraine's defence ministry later confirmed to the BBC that restrictions affecting Starlink connectivity at speeds above 160km/h were detected during the night. The source said the root cause of the issue was still being investigated, leaving open the possibility that the limits could be technical rather than deliberate.

Defence ministry sources further explained that once a vehicle or asset crosses the 160km/h threshold, the terminal simply drops its connection. They said this complication made it harder to conduct drone operations, particularly those involving interceptors and middle-strike drones, and also degraded frontline logistics, reconnaissance, and signal-relaying capabilities.

Beskrestnov emphasised in a follow-up post on Telegram that Starlink remains the most effective tool for enabling Ukrainian interceptors to shoot down Russia's newly developed jet-propelled drones. That assessment underscores how deeply Ukraine's air defence architecture now depends on commercial satellite infrastructure provided by a single foreign company.

The episode echoes a previous controversy in February, when Musk's decision to deny Russian forces access to Starlink blunted Moscow's advance and sowed confusion among Russian commanders. That move was widely seen in Kyiv as helpful, but the latest restrictions demonstrate how quickly the same technology can become a point of leverage.

The Starlink concerns emerged against the backdrop of another night of deadly Russian strikes across Ukraine. Zelensky said at least 600,000 people were left without electricity following overnight missile and drone attacks, with "critical" energy infrastructure damaged in Kyiv, the surrounding region, and the north-eastern city of Kharkiv.

The strikes came despite US President Donald Trump's claim on Sunday that an "energy ceasefire" was in place between Russia and Ukraine. Trump wrote on Truth Social that both parties had agreed to the truce with immediate effect and warned them not to break it, but the violence has continued unabated.

Local officials reported three deaths in Kyiv, where pictures showed residents, some still in their pajamas, with bloodied faces as emergency services worked at the scene of the strikes. Russia's defence ministry said its "massive" attacks had targeted communications and energy facilities used by the Ukrainian military.

Later on Wednesday, at least six people were killed in a Russian drone strike on a warehouse in the north-western city of Lutsk, according to local officials. The cumulative toll has added pressure on Ukraine's allies to accelerate deliveries of air defence systems.

Ukraine's air force said Russia launched 39 ballistic and cruise missiles and 128 drones overnight, of which four missiles and 115 drones were shot down. It was the second consecutive night that Kyiv was hit by Russian missiles, and the attacks arrived without warning before air raid sirens could sound, raising questions about intelligence-sharing arrangements.

Zelensky has said the United States threatened to restrict intelligence sharing if he did not sign up to Trump's energy ceasefire proposal. On Tuesday, Trump denied that Washington was withholding intelligence from Kyiv, but the unexplained absence of advance warnings has fuelled uncertainty in the capital.

Ukraine relies heavily on US satellite systems to track incoming Russian missiles so that alerts can be issued and interception attempts organised. Over the past two nights, however, missiles struck targets in Kyiv with no prior warning, according to the source account, leaving residents exposed and deepening concerns about gaps in the detection chain.

On the diplomatic front, Zelensky was preparing to meet UK Prime Minister Andy Burnham at Downing Street on Wednesday to discuss speeding up air defence supplies to Kyiv. The meeting reflects Ukraine's push to secure more interceptors and radar systems as Russia intensifies its long-range bombardment campaign.

Meanwhile, Russia's defence ministry said 902 Ukrainian drones had been shot down overnight over multiple Russian regions, including Moscow and Crimea, the southern peninsula annexed by Russia in 2014. The figure, if accurate, would represent one of the largest single-night drone engagements of the war and illustrates the escalating scale of cross-border strikes.

Zelensky has repeatedly said Ukraine is ready to halt strikes on Russian oil refineries and other energy facilities if Moscow reciprocates. But Russia's Foreign Minister Sergey Lavrov has rejected the idea, arguing Ukraine does not deserve the "respite" a ceasefire would bring and claiming Europe would use any truce to "pump [Ukraine] with new weapons" and prolong the war.

Russian President Vladimir Putin launched the full-scale invasion in 2022, and Moscow currently controls roughly 20% of Ukrainian territory. For residents of Kyiv, the past two nights have been terrifying. Tetiana Storozhyk, 54, told the BBC she lost everything "in a fraction of a second" when a late-night blast struck her apartment block on Tuesday, one of many personal tragedies behind the mounting casualty figures.
