The cause of a fault in a submarine cable between Finland and Germany is being investigated. Helsinki-based Cinia reported yesterday that a fault has been detected in the Cinia Oy C-Lion1 submarine cable between Finland and Germany early after 4 a.m. on Monday November 18.
“Due to the fault, the services provided over the C-Lion1 are down,” the company said, adding that the details of the fault are yet not known and are currently being investigated.
Corrective measures have been initiated and the repair vessel is getting ready to go on the site. The exact repair time is not yet known, Cinia said, but typically the repair time for submarine cables is between 5 and 15 days.
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 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.
Cinia, a Finnish expert in cybersecurity of digital operating environments and a specialist in critical, high-reliability connections and software, said that more information of the situation will be updated on Tuesday November 19.
A joint statement was issued on Monday November 18 by the Foreign Ministers of Finland and Germany on the severed undersea cable in the Baltic Sea.
“We are deeply concerned about the severed undersea cable connecting Finland and Germany in the Baltic Sea. The fact that such an incident immediately raises suspicions of intentional damage speaks volumes about the volatility of our times. A thorough investigation is underway. Our European security is not only under threat from Russia’s war of aggression against Ukraine, but also from hybrid warfare by malicious actors. Safeguarding our shared critical infrastructure is vital to our security and the resilience of our societies,” reads the statement.
