The point is that even without a malicious actor the odds are way lower than you'd think.

The grandparent comment is total nonsense which sounds smart but is not. Damages from accidents are not independently random either. Or do you think it is virtually impossible that 140 people die on the same airliner? It is likely the same ship cut both either by accident or intentionally.

I am leaning towards sabotage but that two cables were cut means very little.
