While they have this robot and spool up there, they should look at deploying double wires for redundancy... That way you can survive multiple breaks on the line as long as each break is on a different segment.
I'm assuming that they are allowing service loops to be added to the system just for the purpose of allowing for cuts in the line to be fixed. Of course, this was just a puff piece for marketing/PR, so there's lots of details left out. However, now, instead of just the regular crew of linesmen to install/repair cables, you also have to have a robotics crew along.
I was also wondering about how they would handle these cables being replaced, or breaking due to some natural calamity, and so on. Will the locals have a way to repair the damage without the FB staff around? I'm assuming the answer is yes.
