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 on in a post on X.

The global satellite internet service appears to be back up and running after a "failure of key internal software services that operate the core network" was repaired.
