OneWeb service has been restored after the constellation experienced a 48-hour outage this week, Eutelsat Group confirmed on Thursday. 

The outage coincided with the end of the year and began on Dec. 31. Eutelsat said in a statement that the outage was caused by “a software issue within the ground segment.”

The 2024 leap year “seems to be the most likely cause” for the issue, Joanna Darlington, Eutelsat chief communications and investor relations officer, said in a statement to Via Satellite. 

Eutelsat confirmed the constellation is operating nominally again. Darlington told Via Satellite will carry out a full investigation into the outage.

“Eutelsat was fully mobilized and worked with the vendor to restore full service, while maintaining a constant dialogue with affected customers,” the company said. 

Eutelsat owns the OneWeb LEO constellation, which has more than 630 satellites in LEO. Eutelsat recently placed an order with Airbus for a 100-satellite update to the constellation.
