The C-Lion1 cable, 1,200 km long, running across the Baltic Sea from Helsinki to the German port of Rostock, failed today at around 05:00 Moscow time. A sudden loss of communication is most likely due to the fact that the cable has been physically damaged, although the integrity check has not yet been carried out. According to the source, the damage occurred near the southern tip of the Swedish island of Öland, and troubleshooting will take from 5 to 15 days. Cinia added that it is cooperating with authorities to investigate the incident and determine the cause of damage to the submarine cable.
Last year, an undersea gas pipeline and several telecommunications cables under the Baltic Sea were severely damaged in an incident that caused serious concern in the region. According to the Finnish police, the incident could have been caused by a Chinese container ship, which caught a pipeline and telecommunications cables with its anchor.
