Starlink - the satellite internet service owned by Elon Musk - suffered a global outage on September 15. The company announced this on its official website.
The service has become vital for hospitals, schools and frontline military units across Ukraine.
"Starlink is down again across the frontline", wrote Ukraine's top drone commander, Robert "Magyar" Brovdy, on Telegram, as quoted by "Kyiv Independent".
Downdetector - a platform that tracks service outages, reported tens of thousands of complaints from users around the world. The company said it was investigating the cause.
About an hour later, Brody reported that connectivity was starting to "gradually recover," although Starlink has not officially confirmed a full restoration.
This is the second outage in recent months.
The stakes are high for Ukraine, as Starlink has replaced much of the country's destroyed communications infrastructure and supports both civilian and military connectivity.
Since the start of the Russian invasion in 2022, Kiev has received more than 50,000 Starlink terminals, with Poland providing nearly 30,000 - the largest contribution from any single country.
Ukraine's reliance on Starlink has previously been complicated by tensions with Musk.
In July 2023, the billionaire ordered a temporary shutdown of satellite coverage over Kherson region during a Ukrainian counteroffensive in 2022, raising concerns about the vulnerability of critical decision-making systems by private individuals.
