I guess I always knew but never really thought about it, there are cables connecting the world in the oceans. Kind of crazy when you think about it. I am sure the routes are planned carefully but still, the sea floor could be miles deep, unless the cables are not touching the bottom. This might be extremely expensive and vulnerable(hostile intentional attacks and natural events).

Anyone ever think about these cables? For some reason it sort of blows my mind.

What's so strange to think about? We've been running cables under the ocean since 1858.

They are vulnerable. If you want to read a particularly well-informed, nightmare-inducing spy novel discussing what could happen when those cables are cut, check out Breakpoint by Richard Clarke.

The vulnerability are the servers and not the cables. Just research "Denial of Service" attacks.

Each of these cables have multiple redundant paths so that if one cable gets cut, the stream of info just goes through another route. Data centers are designed the same way, with multiple versions of data stored / calculated at various sites and each site having at least one back up piece of equipment the entire way up the power chain from the server to the utility source.

Virtually anything of importance on the internet has multiple layers of redundancy. Also, every time the internet is used (say a search or whatever), at some point in the path, information is traveling through a physical cable somewhere.

Another pondering question for the OP, how does the signal travel all the way across the ocean without defusing to nothing? How does the signal stay amplified?

Yea its interesting to think about: IF THERE IS A SMALL BREAK,how do they easily find it if its 1000s of miles out?

A self-healing ring, or SHR, is a telecommunications term for loop network topology, a common configuration in telecommunications transmission systems.

Submarine cables are roughly 1 pound per foot, so they are fairly heavy and rugged.

A cross section of undersea cable.





What gets me is how small the fiber optic cable is (it's at about ten o clock in the first pic). It's incredible how much data can travel over that small diameter cable.
