SpaceX's Starlink satellite network was back up and running on Friday as engineers hunted for the root cause of one of its biggest international outages the night before, a rare disruption for the powerful internet system set off by an internal software failure.

SpaceX’s Starlink satellite internet service network has been restored after an hours-long outage, the Elon Musk-led unit said in a post on X.

Complaints spiked on Downdetector.com around noon PT on Thursday. The satellite service now says it's 'mostly recovered,' though some people are still not connected.
