The cable is called C-Lion1 and it runs 728 miles between Helsinki and Rockstock. It’s buried 3 feet into the seabed and would have been difficult to cut by accident. When it was laid down in 2016, it broke data speed records. The cable, just by itself, could enable everyone in Finland to jump on a 25Mbps internet connection at the same time.

The C-Lion1 cable between Finland and Germany was severed in the Baltic Sea, its operator said, after damage was reported to another cable linking Lithuania and Sweden.

Germany cites Russia's war against Ukraine and the threat of "hybrid warfare" - as Finnish authorities say it could take two weeks to fix the outage.
