What happened: a speed cap appears on Ukraine's satellite links
Ukrainian military units began noticing the problem in the middle of this week, around 14–15 October. Starlink and Starshield terminals — the satellite dishes that carry Ukraine's battlefield communications — started losing their connections whenever they moved faster than about 161 kilometres per hour (100 miles per hour). Presidential adviser Serhii Beskrestnov said the throttling hit mid-range strikes, front-line logistics and air-defence intercepts, and Ukrainian defence ministry sources said some units lost their links at speeds as low as 45 mph. On Wednesday, the ministry confirmed a 161 km/h limit was still being enforced, though communication quality had improved at speeds up to 160 km/h.
The timing could hardly have been worse. The restrictions coincided with a major overnight Russian missile and drone barrage that targeted more than 15 Ukrainian energy facilities, causing widespread power disruptions. Ukraine's interceptor drones — which chase Russian jet-powered Shaheds flying at roughly 400 km/h — depend on Starlink and Starshield to stay linked to their operators. "Unfortunately, we can't use Starlink or Starshield technology on our territory today to shoot down jet-powered Shaheds," President Volodymyr Zelenskyy told reporters, adding that Ukraine had to fall back on aircraft and other air-defence systems. Ukrainian officials say F-16 fighter jets are now shooting down about 60 per cent of the jet-powered drones.
Zelenskyy says it is deliberate: the Europe test
On Saturday 17 October, speaking to reporters during an online media briefing at the EU summit, Zelenskyy escalated the dispute from a technical complaint to an accusation. Ukrainian teams had driven vehicles equipped with Starlink and Starshield terminals at high speeds in EU countries and inside Ukraine as a controlled test. In EU territory, the systems kept working at 180 km/h. When the same vehicles crossed back into Ukraine at the same speed, the connection dropped. The previous generation of the equipment had worked on drones at up to 400 km/h, he said, citing test logs as evidence.
"The conclusion is that the restrictions apply inside Ukraine but do not apply in European Union countries. In other words, this is a planned operation," Zelenskyy said. He rejected SpaceX's explanation that the speed cap was caused by technical problems, calling it a deliberate restriction. "We lose Starlink and lose the interceptor. The restrictions prevent us from defending ourselves and protecting our people, both at the front and among the civilian population," he added. Ukraine's chief negotiator Rustem Umerov raised the issue directly with US President Donald Trump's adviser Jared Kushner on Friday.
Musk points to the Pentagon; Trump and Rubio deny any order
Elon Musk, whose SpaceX operates Starlink, responded on Wednesday that Starshield is owned and controlled by the US government and that any speed or usage limits are decided by the US military and ultimately the president. That statement put the decision squarely on Washington's doorstep — and Washington has refused to pick it up. Trump said on Friday that he had not restricted Ukraine's access to Starlink and did not believe Musk was responsible.
US Secretary of State Marco Rubio went further on Sunday, flatly denying any White House involvement. "In the United States, nobody ordered that Starlink's speed be slowed down," Rubio said, adding that Starlink is a commercial product regulated by SpaceX, while Starshield is a defence product under US military control that Ukraine does not currently have access to. "Ukraine wants access to Starshield... in order to conduct deep strikes inside Russia. They do not have access to it at this moment. I don't know what Zelenskyy is talking about," Rubio said. In his understanding, he added, the service had been restored.
Not everyone believes the denials. The Telegraph, citing sources familiar with the discussions, reported that Musk himself proposed the speed restriction to Trump and that Trump agreed, opening the way for Pentagon limits on Starshield. Both camps deny responsibility: SpaceX cites a technical issue, Ukrainian contacts point to the White House, and the White House shifts responsibility to Musk. Beskrestnov, writing on Telegram, said it was "clear that this action is not coincidental and is related to the current political situation" — a reference to strains in the US-Ukraine relationship.
Starlink versus Starshield: what the two systems do
The dispute is complicated by the fact that Ukraine uses two different satellite systems. Starlink is the commercial service operated by SpaceX, and Ukraine relies on it heavily for communications and defensive military operations — everything from front-line chatter to steering reconnaissance and defensive drones. Starshield is the militarised version: a defence and military product controlled by the US government, used for offensive military purposes, including the long-range strike missions Ukraine has been conducting against Russian targets.
Ukrainian officials have said the restrictions affected both systems, while Rubio disputes that Starshield is even available to Ukraine — a disagreement that itself illustrates how murky the command chain is. The Defence Ministry said it is examining alternative communication channels and has been in contact with US officials, SpaceX and NATO partners. Business Insider notes that this is not the first friction point: earlier cases in 2022, 2023 and February also showed the limits of Kyiv's dependence on a single billionaire's infrastructure.
