Starlink, owned by Elon Musk, has changed the game in terms of internet accessibility in rural and other underserved areas lacking high-speed broadband infrastructure. It has 2 million US subscribers, and more than 6 million globally.

The major outage came the day after Starlink launched a new cellular service with T-Mobile meant to kill dead zones.

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.
