What would the impact be of Europe to America undersea cables being cut?

Question

Putin has previously stated the goal of seperating Europe and the US.There was recently a suspicious faliure of the undersea cable between Norway and a key arctic satelite ground station.[1]So I'm wondering, what would the consequences be if the Atlantic cables connecting Europe with America experienced a sudden faliure?How much would it inhibit things like say Telegram within Europe?Is there anything we can do to mitigate these risks?[1]: https://www.thedrive.com/the-war-zone/43828/undersea-cable-connecting-norway-with-arctic-satellite-station-has-been-mysteriously-severed

I think you under-estimate the amount of undersea cables that cross the Atlantic.

Even if someone went crazy and tried to sever all of them, traffic is still going to flow, it's just going to take a different and slower route.
The cables can be fixed in a reasonable amount of time, so there is little incentive for anyone to even attempt this.

This would make Russian submarines active combatants and put the entire Russian sub fleet at risk.I think the Russian military hierarchy would put up a strong argument against doing this.

Unlikely to happen, for several reasons:
1) Putin or any government cutting the Transatlantic cables could be seen as an act of war.
2) The Internet would just route around the issue(s).
3) Any ship caught cutting cables in the Atlantic would greeted by the US/UK Navy.
4) As someone else pointed out, there are a lot of Transatlantic cables, so it actually might be hard to cut enough of them to make an impact.
