> Nunavut is the only province or territory in the country [Canada] without access to fibre internet. The project would bring fibre to both Iqaluit and nearby Kimmirut.
Right now, everything is over satellite. Too bad the big "internet cache" systems don't have sneakernet approaches to filling their caches. Unsure if their local ISP does any kind of caching. So every stream/download/update, etc. is its own "hit" over the downlink.
Thanks to Canada's terrible mobile telecom pricing and lacklustre competition, a cell phone with a dataplan in this territory is cost-competitive with the rest of the country...
Before that moment the fastest way to get a message from Europe to America was aboard a ship; two weeks or so. After that it could be sent over a cable with Morse code.

You scroll down to what you think is the map, but it immediately gets covered by a caption, so you scroll down more ...
It turns out that downloads for the actual map are at the top of the page.
Fortunately mmwelt posted another link for exploring:
[1] https://submarine-cable-map-2023.telegeography.com/images/Su...
It uses mapbox.js and tiles have URLs like this one: https://tiles.telegeography.com/maps/submarine-cable-map-202...
https://dezoomify-rs.ophir.dev/ is helpful.

Then you've got this link to the SW tip of UK, that then links to France (via Guernsey & Jersey): https://www.submarinecablemap.com/submarine-cable/pan-europe...
There might be an overall direct fibre link.
But yeah, Ireland is at risk of the UK cutting most of their continental Europe capacity.
I've seen some strange investments though that don't seem to add much more on top of what's already there, like this company's: https://crosslakefibre.ca/network/ But maybe despite ample existing infrastructure, the incumbent providers suck so they can make a successful go at providing a bypass.
I have long been thinking that the NSA must have some high capacity "black" cables to help the surveillance of the internet. Primarily to capture data, sending all the captured data back through the public internet would be counterproductive.
A 5eye private subsea network?
I would assume other countries have some for similar reasons
I wonder how well protected they are specifically in the Suez Canal. Presumably the whole area is pretty well surveilled by the Egyptian government, but I have no clue. I just think it's really interesting how many cables are (understandably) routed this way and wonder whether there is full backup redundancy in the few cables running around south of Africa.

That said, Djibouti is a major cargo transport hub for Ethiopia, and is probably a network transport hub as well. Ethiopia is the 2nd most populated country in Africa and that would justify a lot of cable landings.
There is HVDC equipment on both ends and typically each end is sufficient to power the entire cable independently to allow for the cable to continue running through maintenance, shunt faults (basically something earthing out on sea water) or a single failed repeater.
Stop asking me for WebGL, I will not give it to you.
