C-Lion1 is a submarine communications cable between Finland and Germany. The cable is owned and operated by the Finnish telecommunications and IT services company Cinia Oy. It is the first direct communications cable between Finland and Central Europe; previous connections have been through Sweden and Denmark.
The cable operated from May 2016 until November 2024, when it was damaged. Some officials suspect it was an act of sabotage.
