Overview

• Between 21:00 and 23:30 CET on July 25, Starlink functioned at just 16% capacity, leaving most users without internet access
• Ukrainian soldiers and civilian support services, including hospitals, experienced severe communication disruptions during the outage
• Michael Nicolls confirmed the issue stemmed from a failure in Starlink’s internal network management software rather than any satellite malfunction
• Starlink is probing a possible coding bug or a flawed update tied to its new SMS-via-T-Mobile feature as the root trigger of the software failure
• With over 8,000 satellites serving six million users across 140 countries, the outage highlighted both the network’s global reach and its technical vulnerabilities
