Yi Peng 3 crossed both cables C-Lion 1 and BSC at times matching when they broke

October 2023 there was similar incident where Chinese cargo ship cut Balticonnector cable and EE-S1 cable. Chip named 'Newnew Polar Bear' under Chinese flag and Chinese company Hainan Xin Xin Yang Shipping Co, Ltd. (aka Torgmoll) with CEO named Yelena V. Maksimova, drags anchor in the seabed cutting cables. Chinese investigation claims storm was the reason, but there was no storm, just normal windy autumn weather. The ship just lowered one anchor and dragged it with engines running long time across the seabed until the anchor broke.

These things happen sometimes, ship anchors sometimes damage cables, but not this often and without serious problems in the ship. Russians are attempting plausible deniability.

What are some concrete reasons why someone would want to damage these cables? Who benefits?

Assuming it was intentional, just trying the waters. Testing what the response is, who actually responds versus who's willing to sweep the incident under the carpet, how hard any response is and how quickly it happens, how much of the internet infrastructure is affected for how long, etc... etc... that's a lot of useful information as preparation for an actual attack.

This is really interesting how you’ve explained it.

In many professional fights the competitors start matches with light, quick jabs to probe their opponents defense.

This feels just like that now that you put it this way. I never connected those dots though.

Maybe it's because I'm Swedish and we've experienced Russia's "probing defenses" tactic for a very long time (mainly "breaking" into Swedish airspace with airplanes, and discovering submarines at the Swedish shores), but I always thought this was common knowledge, always interesting to learn it isn't for everyone :)

The situation escalated beyond probing, this is tit for tat response for Ukraine getting and launching US tactical missiles. Russia seems to be now aggressively monitoring and raiding the submarine pipes and cables. Blowing up of Nord Stream made Russia go ballistic.

> The situation escalated beyond probing

Not sure we understand "probing" differently. Russian currently is at the edges, testing the responses from things like cutting cables and otherwise interfering with the infrastructure. This is what "probing" means for me. "Beyond probing" would be actually launching attacks one way or another, which we haven't seen yet (except of course, for the Ukraine invasion).

> actually launching attacks one way or another, which we haven't seen yet

On the contrary. The attacks have been ongoing for years now. You're looking for the tanks and missiles when the attack is actually happening right under your feet. Rot and corruption are more powerful than any bullets or missiles.
