Your private messages travel under this beach
In Porthcurno, Cornwall, there’s an old telegraph cable landing station. It’s how Britain talked to the Empire — and it’s now a museum. But the technology here isn’t quite as obsolete as you might think.
Thanks to Steve and all the team at the Porthcurno Telegraph Museum! You can find out more about them here: https://pkporthcurno.com/

How do you even make 15,000 miles of fibreoptic cable and run it?!

We have similar at Flinders, Victoria, Australia. 😉

They've set one of these up in Bude, just a bit further up Cornwall

"There is a beach somewhere near you" is such an islander thing to say.

Why is there a cable going from Britain to Japan? Internet being a relayed packet switched network, it doesn't seem to make any kind of sense. Or apparently it makes business sense, I guess a direct connection between Britain and Japan is worth an undersea cable going all over the place.

World Wide Web nowadays is literally a web of ginormous cables between entire continents.

100 gigabits per second or 100 gigabytes per second?
@RetroLuxNZ
April 20, 2026 at 2:12 pm
Correct me if I'm wrong, but isn't the speed of data transmission normally measured in gigabits per second? Tom said "100 gigabytes per second" in the video. They are two very different measures.

It's also one of the best Bass fishing beaches in the country when the tides are right

It's not magic that makes it happen. Networking is just as impostant as the software, even more so as nothing can happen without the infrastructure to send those 0s and 1s.

question, couldn't the enemies pick the cable not directly near the beach, but more far away (some kilometers) and then simply cut it? By a submarine or the like?

Do these huts still exist or I imagine there data centers now?

Hey Tom, you should do two videos. One about the old London Bridge now in Lake Havasu and about the old GWR atmospheric railway from Exeter to Newton Abbot.

I worked for an ISP that owned many of those cables. You would be amazed on how often they get cut or damaged. That is why there are multiple lines and protocols like BGP in place to re-route traffic.

100 GB of data per second seems low for a cable to Japan considering all of the Japanese porn…

The new landing station is at Skewjack, which is closer to Land's End. When I was young, there used to be a surf village there, called Skewjack Surf Village. Now it looks more like a flight hangar or something.

For years I always wondered about these cables.
I wondered if the cables were just kind of suspended there, literally hanging across an underwater mountain range in DEEP water (Of course not! How ludicrous!)😜

Neal Stephenson wrote an EXTENSIVE article about undersea cables for WIRED, and this place figures prominently.
The original telegraph cables and ships were amaaaaazing.

I'm interested in why Faial was spelled Fayal? I've never seen the name of my parents home island spelled with a "y" ever, until this video.

Being in the exact middle of Canada I don't think there is a beach that close unless the cables come up through the great lakes then maybe there's a beach within 1000 miles of me

Huh, What if you cut one of those cables? I am guessing it is a crime but what crime would be charged with?
