Ukraine warns of fresh Starshield disruptions as U.S. envoys arrive in Moscow for talks with Putin

President Volodymyr Zelenskyy said Ukraine was investigating what he described as fresh restrictions on SpaceX's Starshield service over the country, after similar speed limitations were imposed last month.

"Our units have been recording significant disruptions to Starshield's operations over the territory of Ukraine for several days now – along the entire front line and in the temporarily occupied territories of Ukraine," he wrote on X early Thursday.

Starshield is SpaceX's satellite network for government and national-security use, built on Starlink technology.

CNBC has reached out to SpaceX and the White House for comment.

"The Ukrainian military have already investigated the circumstances, and these are not random errors but systematic speed restrictions," he said.

Zelenskyy said the restrictions imposed an effective speed limit on terminals of 161 kilometers per hour (100 miles per hour), disconnecting anything that was moving faster.

He added this made it harder for Ukraine to intercept Russian jet-powered drones.

"There have already been strikes that got through because our interception systems cannot reach sufficient speeds and are unable to intercept in time."

The comments came as U.S.-brokered peace talks wrapped up in Abu Dhabi on Wednesday and U.S. special envoys Steve Witkoff and Jared Kushner arrive in Moscow for further talks with Russian President Vladimir Putin.
