<<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? What about sabotage -- wouldn't it be easy (unlike phone lines running
along 25 KV power lines) for a well financed entity to cut lines, or multiple lines quickly & easily? I would also
imagine some parts of the ocean floor are too deep for the submarines, correct?>>

You are asking for perfect world and perfect life. I do not know such a thing even exists !!. Your question made me wonder about your motive.

Uh! Oh! Now we all have something ELSE to lose sleep over...God, I live in Seattle and some Islamic nut could sneak a tactical nuke into the harbor and blow up MSFT(Redmond is after all only a suburb), or we could have a Richter 8!( they are estimated to reach 9 about every 400-600 years and it's been awhile), or the nuts in this state who just passed prop695 could drive Boeing out of the Northwest( Boeing has made some threatening remarks), or a Richter 8 could hit silicon valley and make the recent earthquake in Asia( chips) look like peanuts!
Qualcomm is there, Loral is there, hell, who ain't( well Bernie Ebbers is stupid enough to live in Mississippi but nobody's perfect.
I think we should all start seriously considering a very unpleasant fact: the leading cause of death in the US is life! Shit! Nothing is safe. Jim Black

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>.

DN

Do not forget about sea floor spreading. Ya know Europe and North America are moving apart at about 2 centimeters per year. I hope they laid extra cable to account for that <lol>.

Just kidding, I think you voiced a valid concern and was glad to learn in one of the replies to this message that this type of contingency may not be catastrophic.
