SpaceX has limited some Starlink satellite internet service used by Ukraine's military, Ukrainian officials said on Wednesday. They said the change disrupted several drone missions.

Serhiy Beskrestnov advises President Volodymyr Zelenskyy on military technology. He said SpaceX added the limit overnight, Interfax-Ukraine reported. It affects the military version of the service, called Starshield. Terminals stop working when they move faster than 100 miles per hour.

"Our defence forces did not receive a warning about this limitation, and this led to the disruption of several missions," Beskrestnov wrote on Telegram, Reuters reported. He said the timing was no accident and was linked to "the current political situation," Interfax-Ukraine reported. Hromadske noted that no proof of a political motive has been made public.

Ukraine's 7th Rapid Reaction Corps said some units had to cancel missions. "The drones kept moving, but these interruptions made them harder to control," it said in a statement to Reuters. The unit said links could drop for 10 to 20 seconds at speeds of just 110 to 120 kilometers per hour.

Starlink has been key to how Ukraine's troops stay in touch since early in Russia's invasion in 2022, Reuters reported. Units use it to talk to each other and to fly long-range drones. It is hard to jam. Ordinary Starlink terminals kept working, Hromadske reported.

SpaceX did not immediately respond to a request for comment, Reuters said. The limit came as the Trump administration presses Ukraine to stop hitting Russian oil plants. On Tuesday, SpaceX owner Elon Musk wrote on X that "Zelenskyy has gone too far," Hromadske reported.

The outage came as Russia fired missiles at Ukraine for a second night with no early warning from the US, the Guardian reported.

What we know: SpaceX limited the military version of Starlink in Ukraine overnight, and some drone missions failed.
What we don't: Why SpaceX made the change, and whether it will be lifted.
