I'm Swedish, if that matters, and recall reading about (accidental) cable breakages all the way back to at least 2010 sometime. As mentioned elsewhere, there are between 100-200 cable breakages annually

> Yes! Cable faults are common. On average, there are over 100 each year.
> Unintentional damage from fishing vessels and ships dragging anchors account for two-thirds of all cable faults.
