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.

Starlink appears to have largely recovered from a widespread outage on Thursday afternoon that affected its services across the United States and other parts of the world. Reports of service disruptions flooded outage tracker Down Detector earlier in the afternoon, with users experiencing internet outages and, in some cases, total blackouts.
