By Max Hunder KYIV (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.

Starlink's biggest international outage on Thursday, caused by 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.

A brief outage of Starlink, Elon Musk’s satellite internet service, impacted Ukraine’s front line military communications, just hours after Russian drones hit the city of Kharkiv. CNN’s Nick Paton Walsh reports from Kyiv.
