A fault in the Cinia C-Lion1 submarine cable between Finland and Germany

A fault has been detected in the Cinia Oy C-Lion1 submarine cable between Finland and Germany and corrective measures have been initiated

A fault has been detected in the Cinia Oy C-Lion1 submarine cable between Finland and Germany at 4:04 a.m. (EET) on Monday 18th November, 2024. Due to the fault, the services provided over the C-Lion1 are down.

The cause of the cable fault is unknown. Cinia has submitted a request for investigation to the National Bureau of Investigation (NBI) on 19 November 2024.

Corrective measures have been initiated. The repair vessel Cable Vigilance left Calais, France, on Thursday 21 November at 9 p.m. (EET) and it arrived at the fault site early on Monday morning 25 November and started the repair work. Estimated completion of the cable repair is by the end of November.

The location of the cable cut is in the Baltic Sea, in the Swedish Exclusive Economic Zone, east of the southern tip of Öland, about 700 km from Helsinki.

Finland's international telecommunication connections are routed via multiple routes and the impact of a single cable failure depends on the resilience of the service providers' connections.

C-Lion1

C-Lion1 is a submarine telecommunications cable between Finland and Germany with a length of 1173 km. The submarine cable was launched in 2016 and connects Central European telecommunications networks to Finland and other Nordic countries.
