Ukraine says Starlink's global outage hit its military communications

By Max Hunder

KYIV, July 25 (Reuters) - Starlink systems used by Ukrainian military units were down for two and a half hours overnight, a senior commander said, part of a global issue that disrupted the satellite internet provider.

Ukraine's forces are heavily reliant on thousands of SpaceX's Starlink terminals for battlefield communications and some drone operations, as they have proved resistant to espionage and signal jamming throughout the three and a half years of fighting Russia's invasion.

Starlink experienced one of its biggest international outages on Thursday when an internal software failure knocked tens of thousands of users offline.

"Starlink is down across the entire front," Robert Brovdi, the commander of Ukraine's drone forces, wrote on Telegram at 10:41 p.m. (1941 GMT) on Thursday.

Starlink, which has more than 6 million users across roughly 140 countries and territories, later acknowledged the global outage on its X account and said "we are actively implementing a solution."

Brovdi updated his post later to say that by about 1:05 a.m. on Friday the issue had been resolved. He said the incident had highlighted the risk of reliance on the systems, and called for communication and connectivity methods to be diversified.

"Combat missions were performed without a (video) feed, battlefield reconnaissance was done with strike (drones)," Brovdi wrote.

A Ukrainian drone commander, speaking anonymously to discuss sensitive matters, told Reuters his unit had to postpone several combat operations as a result of the outage.

Oleksandr Dmitriev, the founder of OCHI, a Ukrainian system that centralises feeds from thousands of drone crews across the frontline, told Reuters the outage showed that relying on cloud services to command units and relay battlefield drone reconnaissance was a "huge risk".

"If connection to the internet is lost ... the ability to conduct combat operations is practically gone," he said, calling for a move towards local communication systems that are not reliant on the internet.

Reuters reported on Friday that Starlink owner Elon Musk issued an order in 2022 to cut Starlink coverage in certain areas of Ukraine as Ukrainian forces were waging a counter-offensive to take back occupied land from Russia.

As of April 2025, according to Ukrainian government social media posts, Kyiv has received more than 50,000 Starlink terminals.

Although Starlink does not operate in Russia, Ukrainian officials have said that Moscow's troops are also widely using the systems on the frontlines in Ukraine.

"The outage was due to failure of key internal software services that operate the core network," Starlink vice president Michael Nicolls wrote on X, apologising for the disruption and vowing to find its root cause.
