The underwater data transmission cable C-Lion1, which runs through the Baltic Sea between Finland and Germany, has been severed. The telecommunications connection has been disrupted, Yle reports.

The Finnish state-owned company Cinia, which builds fiber optic networks and provides telecommunications services, has reported a malfunction in the underwater cable between Finland and Germany.

The telecommunications connection has been interrupted, and the cause of the malfunction is currently unknown.

According to the Ilta-Sanomat newspaper, the cable has been severed. Samuli Bergström, head of the Traficom Cyber Security Center, confirmed that the C-Lion1 cable is damaged but did not specify where exactly the break occurred.

Cinia's CEO, Ari-Jussi Knaapila, stated that it is too early to judge whether the C-Lion1 cable was intentionally damaged.

He said that it is currently impossible to assess the cause of the break, but such incidents do not happen in those waters without external influence.

The company has begun repairs on the cable, but it is still unknown how long it will take to restore the connection. Typically, the repair time for underwater cables ranges from 5 to 15 days.

The C-Lion1 cable is 1,173 kilometers long, stretching between a bay in Helsinki and Rostock, Germany. It was put into operation in 2016 and is the only cable that directly connects Finland to Central Europe.

In February, we reported that the Houthis had disabled four underwater cables between Saudi Arabia and Djibouti, causing a major disruption in communication between Europe and Asia.
