A great map and shows just how much "brick and mortar" infrastructure the information age depends on.

Interesting that the only undersea cables that come on shore in Canada are at the station in Sambro. I would have expected a similar landing on the west coast.
 
There used to be one on Vancouver Island

originally Bamfield

and then Port Alberni
This Article from 2004 suggests that the station was going to be used again ... but a quick search revealed nothing more on this .

Seems like the UK might be sitting on a fair bit of bandwidth.  I wonder if that counts for anything when bargaining with the EU?

Allo? Allo? Allo?
 
Not my field, but ...

There used to be a lot more submarine cables and they all shared a couple of characteristics:

    + They were (still are) expensive to lay (an attribute that all cables, long and short, aerial, surface, buried and submarine, alike share);

    + They were difficult (some almost impossible) to repair;

    + Their "latency" (lack of that 1/4 second delay thing you get on satellites when your signal has to travel 75,000+ km) is very good;

    + They had a milited (20 yearish) life span; and

    + They had (relatively) low bandwidth (capacity).

Newer fibre optic cables are still expensive to lay and hard to repair if they break but they have absolutely gifuckingnormous bandwidths and they have a long(er) lifespan (35-50 years?).

Satellites have eaten into submarine cables profit margins; while they cannot replace them (bandwidth is too low), they can be a lot more flexible - locatable terminals, steerable beams, etc, and they are (relatively) cheap.
