So why did this happen and why won’t it
happen again?
It has happened before a couple of times before between 2020 and
now, all related to subsea landslides.
I am not a marine geologist and have no interest in the profession,
so I cannot speak to your questions re: the state of the continental
shelf and all. But what I can say is that the repair vessels have no
reason to provide incorrect information for the cable failures, as
that does nobody any good, and would hurt their credibility. While
submarine cable operators are generally secretive, they are quite
open about what caused an outage.
It is my understanding that the last WACS repair was completed by
moving the repaired section farther out from the fault location to
avoid a similar issue in the past.
We shall just have to wait and see if that helps, or not.
