SpaceX's Starlink suffered one of its biggest international outages on Thursday when an internal software failure knocked tens of thousands of users offline, a rare disruption for Elon Musk's powerful satellite internet system.

Starlink said it had a “network outage” on Thursday.

As of 5:54 p.m. ET, 56 percent of Starlink users were reporting internet issues, while 43 percent were reporting total blackouts.
