Hold on. Who says this sabotage?
These incidents happen all the time without sabotage being involved. A ship sank off the coast of Pakistan and took out both international cables serving the country ...
We had the undersea earthquake that seven seven cables in the Taiwan straits.
The truth is that physical diversity is an ideal, not a reality.
I have seen lots of accidents that took multiple operators and seriously disrupted in a given locality.
The only difference here is that in the Heart of Geek Territory. Hence the Natives are restless ...

Seriously though I want to start some discussion around outside plant
protection. This isn't the middle of the ocean or desert after all.
There were multiple fiber cuts in a major metropolitan area, resulting
in the loss of critical infrastructure necessary to many peoples daily
lives (though twitter stayed up so it's all good). :) It would appear
that this was a deliberate act by one or more individuals, who seemed to
have a very good idea of where to strike which resulted in a low cost,
low effort attack that yielded significant results.
So allow me to think out loud for a minute....
1) Why wasn't the fiber protected by some sort of hardened/locked
conduit? Is this possible? Does it add extensive cost or hamper normal
operation?
2) Why didn't an alarm go off that someone had entered the area? It was
after business hours, presumably not in response to a trouble ticket,
and as such a highly suspicious action. Does it make sense for these
access portals to have some sort of alarm? I mean there is fiber running
through and as such it could carry the signaling. Would this be a
massive cost addition during construction?
3) From what I understand it's not trivial to raise a manhole cover.
Most likely can't be done by one person. Can they be locked? Or were the
carriers simply relying on obscurity/barrier to entry?
