Eutelsat's OneWeb constellation experienced a significant 48-hour outage due to a software issue related to leap year calculations, affecting its satellite broadband service.
The satellite broadband service outage was caused by a leap year problem impacting the GPS-to-UTC offset. This oversight resulted in significant connectivity disruption.
The incident highlighted the importance of thoroughly accounting for leap years in software, as the extra day can lead to critical errors in time-dependent systems.
Unlike the Y2K incident, which was preventive in nature, OneWeb's issues arose from inadequate software design regarding leap years, impacting communications due to timing discrepancies.
