WhatsApp SpaceX’s Starlink suffered one of its biggest international outages on Thursday when an internal software failure knocked users offline, a rare disruption for Elon Musk’s powerful satellite internet system. Users in the US and Europe began experiencing the outage at around 9pm SAST, according to Downdetector, a crowdsourced outage tracker. Starlink, which has more than six million users across 140 countries and territories, later acknowledged the outage on its X account and said “we are actively implementing a solution”. The outage was due to failure of key internal software services that operate the core network Starlink service mostly resumed after two-and-a-half hours, Michael Nicolls, Starlink vice president of Starlink engineering, wrote on X. “The outage was due to failure of key internal software services that operate the core network,” Nicolls said, apologising for the disruption and vowing to find its root cause. Musk had also apologised: “Sorry for the outage. SpaceX will remedy root cause to ensure it doesn’t happen again,” the SpaceX CEO wrote on X. The outage was a rare hiccup for SpaceX’s most commercially sensitive business that had experts speculating whether the service, known for its resilience and rapid growth, was beset by a glitch, a botched software update or even a cyberattack. Doug Madory, an expert at the internet analysis firm Kentik, said the outage was global and that such a sweeping interruption was unusual. “This is likely the longest outage ever for Starlink, at least while it became a major service provider.” Network upgrades As Starlink gained more users, SpaceX has focused heavily in recent months on updating its network to accommodate demands for higher speed and bandwidth. The company in a partnership with T-Mobile in the US is also expanding the constellation with larger, more powerful satellites to offer direct-to-cell text messaging services, a line of business in which mobile phone users can send emergency text messages through the network in rural areas.
