SpaceX's Starlink successfully rectified a malfunction within two and a half hours, identifying the root issue.
In the early hours of July 25, 2025, SpaceX's Starlink satellite network experienced a 2.5-hour outage, affecting tens of thousands of users worldwide, including critical users such as the Ukraine military and T-Mobile’s satellite services.
The cause of the outage was a failure in key internal software services that operate the core network, resulting in a disruption of core network functionality and a wide-ranging loss of connectivity. This incident marked a rare disruption for Starlink, whose network outages of this scale are unusual [1][2][3].
Starlink engineers swiftly responded and implemented a solution to restore service. By 1:05 AM, all fronts reported connectivity had been restored [4]. SpaceX and Starlink’s leadership publicly apologized for the disruption and emphasized their commitment to identifying the root cause to prevent similar incidents from happening again [2][3].
The company has initiated a thorough investigation to find the root cause of the software failure and committed to enhancing the robustness of the internal software services that run the core network. They are also continuing to expand their satellite constellation and ground infrastructure to increase network capacity and resilience [4].
In Ukraine, Starlink satellite communication terminals stopped working on the evening of July 24. The issue was announced by Starlink Vice President Michael Nichols on the social media platform X. The affected terminals were used by Ukrainian military forces for internet access, communication among troops, drone navigation, and other purposes. However, the specific cause of the outage in Ukraine was not specified [5].
Starlink has not yet provided updates on their plans for a thorough analysis or preventive measures in response to this specific outage in Ukraine. Nevertheless, the company intends to take all necessary measures to prevent a similar outage from happening again.
Following the restoration of connectivity, the current status of Starlink's network operations in Ukraine is unclear. The company has not issued any updates on this matter.
