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.

After the Nordstream pipeline attacked and destroyed, its reasonable to expect shortened lifetimes for undersea cables and sattelites.

it sounds like you've probably never seen this - tanker Minerva Julie (belonging to Putin's friends) traveling through the Baltic Sea suddenly decided to hang around for a week right at the same place where couple weeks later Nord Stream exploded:

I think it's pretty clear that the NordStream explosion was a joint US-Russia-Ukraine operation.
