<< Now that GBLX has (some) fiber laid and it's maintaining it with the subsidiary company via submarines, what
do they plan to do if there is a break?>>
They use ships, not submarines.
The cable feeding into the shoreline is hardened to avoid accidents like anchor drags, etc. I toured a AT&T cable laying ship years ago before they were laying fiber and had this all explained to me. Believe it or not, they have the ability to determine where the break occurred, go out in the middle of the ocean and find the cable, pull it up to the ship, make repairs, then lay it back down. I presume they do the same thing with fiber. Back then the primary problem was failed repeaters.
It is pretty sophisticated process to lay cable across the ocean. The floor bottom isn't smooth. You have canyons, mountains, etc., and the cable must lay entirely on the floor. Obviously you don't want it dangling between two submerged mountain peaks!
As far as breaks in the cable, whether intentional or not, remember GBLX routes are all configured as rings. If one link fails, the traffic immediately flows on the other path. The customer sees nothing, the offending link is repaired, and life goes on.
I believe GBLX pioneered the ring architecture across the oceans. Previously circuits were laid as point to point installations, and failures were much more of a problem.
Sorry, you will need to find something else to lay awake over <g>.
