How long are you in Cornwall? Do you have plans to do any other videos in Cornwall? I live in Falmouth. It would be nice to come and meet you and the team with my Cocker Spaniel - Winston
Ste Richards generally speaking, unless it was filmed in London, by the time you see a video, Tom's long moved on from where it was filmed. Editing takes time, you know! If I'm remembering the social feeds right he was in Cornwall like, two weeks ago? This was probably filmed then. But if you know of anything appropriate for a video near Falmouth, email him about it and he might come back sometime!
The British Goverment and Intelligence services are already watching you, I know about the cables and Know that the nearest one to me is between sweden and denmark at copenhagen. That is a Terrabite cable though and not merely a few hundred GB. The other cable is going through to Germany. :P
Stijn Stevens yeah I was thinking the same, but there's multiple cables and usually Internet speed is usually in mega bits not mega bytes so that's a lot of people it can service
We (I'm from Guernsey) also get a fair amount of our electricity via undersea cable from France. It's entirely too scary what a wayward anchor could take out, for any nation.
There is a lot packed into the phrase "not a coicidence." The UK is part of the Five Eyes, a coalition of the US, UK, Australia, New Zealand, and Canada (basically the five most industrial English speaking countries with good relations). These countries all spy on each others internet activity and then share the data so that each can then get access to data about their own citizens and, well, the majority of communication around the world which usually passes along the cables into or out of at least one of them at some point. The organization started during the Cold War, became public in the 1990s, and had the internet signals intelligence program leaked by Snowden a few years back.
Snowden's not a kooky conspiracy theorist drawing conclusions from a bunch of coincidences and blurry photos. He released the intelligence agencies' own documents, discussing the program and how it works. Then he fled the country to avoid arrest. I guess the right to petition for redress of grievances doesn't apply if those grievances include pointless, dangerous mass surveillance schemes.
It might have already. Assuming Tom uploaded the video from the UK, somewhere along the line of it being mirrored across TH-cam's various worldwide servers, it's probably going through there.
Greetings from the US, with over 50k views already (actual views probably much higher), this video has been under that beach I'm sure. If it wasn't uploaded in the UK, I'm sure someone in the UK has already watched it.
That's the point, In WWII this was the type of secret you told the Germans but not your own people. So people planning landings had something to worry about. Still probably used less fuel than a FIDO airfield when running.
Back in the day when I worked in a corporate mainframe department, I was in Sunnyvale CA and we were satellite linked to an IBM in Hartford CT. Those half second delays you mentioned were multiplied by the protocol used by our 3270 terminals, to the extent that a screen refresh meant a coffee break.
I love old technology, not only is it extremely interesting to learn how computers and communication have progressed but also the components and equipment used to build it are quite impressive in their function and design, the techno-steampunkesque esthetic of the valve terminations (at 0:50) is not as common (if at all incorporated) in the design of modern technology.
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.
I was just staying in porthcurno on holiday when this video was being recorded! When I was at the museum I though it might be something you would be interested in!!
I've actually been here, but little did I know that people's conversations were stil running under that beach! Great video

Went to see the beach, hut and museum about two years ago. The museum was one of the most interesting of my life! Very well organised and presented. As of the subject matter... everything about communication from smoke to cell phones. Absolutely fantastic!
What's interesting is there are several undersea cable terminals in western Greenland. They seem to be stopovers for cables between the Canadian Arctic and Britain / Europe. It wouldn't surprise me if the military was involved.
Not hard to realize when you work for a major network provider, heck *today* (well I guess technically yesterday, but I have Sunday's off) a sea cable going from mainland the Netherlands to Schiermonnikoog, one of the tiny island just off the northern coast, was broken. Luckily there were more fiber optic cables and all the island's connections could be migrated to the cable used by the mobile data network.
Really love your videos. They're short and informative.. not drawn out to meet the best time to return ratio (not that I would hate if you had to.) Good work dude.
I'm so happy to finally see this video come up! After the post of you using at A1 bus service down to portcurno went up on Instagram it was only a matter of time! I have visited this museum loads and visit the back regularly. Actually I just got back from Cornwall yesterday!! Great video!
Oddly enough there is a news story here in the Netherlands that the island of Schiermonnikoog lost its cable connection two days ago. There is no cable tv, no landline phone connection, or internet there anymore and even ATMs no longer work. Mobile phones (and internet through mobiles) do still work through a different connection. They've only just managed to set up a workaround, to make it work till the fibre optic cable is fixed again.
I've been there! Tom, are you going to visit and do a piece on the Minack Theatre carved into the cliff around the corner? That beach also has a shelf of sand that drops like a cliff under the water in just a few feet. Walk out 10 feet into the water and you go from paddling to treading water.
Sounds like the opposite of Lake Balaton in Hungary, where you walk for several minutes just to get the water up to your midriff, and start muttering "get on with it!".
It might have at some point. Although TH-cam mirrors its videos on servers in each country, so that you don't have to stream them from across the other side of the world.
Mark Thomas' channel has a great 1 hour documentary on the 'secret cables of Cornwall' and those Cornish 'houses' with suspiciously large numbers of manhole covers outside!!
Yes there are a lot of tack welded manhole covers. Screwjack farm has the biggest airconditioned hanger size barn that I have ever seen. Coach loads of white shirted 'farm workers' turn up to very posh farm buildings with no windows and a vacuum of tractors. The story repeats all the way round to Bude.
Here's a funny story, I was in primary school in Jersey when the wires were cut undersea. Our teacher had his entire lesson planned on this website, and obviously it didnt work. His solution? Making boxes into computers and pretending that it worked. That's one way to entertain 30 11 year old 😂😂
My father worked for a company that laid undersea cable, and when I was twelve I got a tour of one of the cableships. Very impressive. They were one of the few private entities that were given access to the really accurate GPS that was normally reserved for the military.
So I live in Jersey. It's a small island in the English Channel off the coast of France. I remember when the internet connection loss happened. It damaged one of the two cables (I think), so Jersey Telecom had to route everyone's traffic through a single cable. This meant VERY slow internet for basically everyone on the island.
Whilst you’re in Cornwall, you might want to check out the Minack Theatre, it’s a gorgeous cliffside theatre with a rich history that I’m sure would interest you
Was there just last week myself, what a great museum it is. Not a coincidence...is probably the fact that the museum makes almost no reference to teleprinter code, rather than morse which leads me to think some elements of their work are still hush hush. The Minack is absolutely spectacular - ended up walking up from the beach which is a bit of a climb!
Well, he's human and in this case, according to wikipedia, he made a mistake - it's Gbps (bits) and not GB/s (bytes). Also, as a rule of thumb, if the subject is network speed it's a safe assumption that the unit is bits per second.
Networking is almost always measured in gigabits, so unless it's actually an 800 gigabit capable fibre optic cable, I think he might have got muddled up. On second thoughts having googled it, it is in fact 100gbit/s, not 100gbyte/s.
It's unfortunately bites but it's not yet at full capacity, the cable was design to be upgradable to 500 Gbps. And there are other cable like AAE-1 that can go to 40 Tbps
I remember wandering around those bunkers back when it was all still owned by Cable and Wireless. Also the Minack Theatre is cut into the cliff just around the headland where you can see some steps cut into the cliff.
Very interesting! We've got a cable landing in Hermosa Beach, but you wouldn't know it--the only evidence of it is a manhole marked "TELECOM" in the middle of 25th street where the Pacific FO cable meets the trunk line going to One Wilshire.
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.
Adam Hart Davies (whatever happened to him) did a section of one of his shows years ago about Porthcurno and that inspired me to take my family there (but of course it was me that was the most interested). Fascinating place!
I will be surprised if there isn't a video on the Minack Theatre soon, it's an open top theatre built on the side of the cliff looking out into the sea. It is right next door to where he is now in this video. Surprised i didn't catch a glimpse of it in this video.
You’re making the assumption there that the only communication satellites are in geostationary orbit. There are hundreds of low earth orbiting comsats like Iridium and Orbcomm. The Iridium fleet actually orbits low enough we can see them as momentary flashes in the sky as they reflect off sunlight, termed “Iridium Flares”
And what you are forgetting on your side are the cost and data capacity differences. Cables are going to be cheaper than to launch a whole fleet of satellite and the signal in a cable is re-amplify every 80 km to be able to carry that much data.
Pierrick Le Berre Google laid a 9000km cable for about $300 million. A Falcon 9 is about $60 million (less if you’re ok with a relaunched Rocket and they do offer a bulk discount) and can carry up to ten satellites per launch to low earth orbit. So you can launch a fleet of 50 satellites to LEO for about the same cost as 9,000Km of cable. As the Falcon Block 5 comes into its own, each designed for 10 flights between refurbishments and theoretically 100 flights total, that cost will significantly drop.
The construction company I used to work for was massively behind on a government project. The media was coming to do a video walkthrough the building, so even though there were cables missing from sockets they still put the sockets on the wall to make it look finished... And then we went back to work the next day making the place a really finished :D
3:19 reminds me of old videos/articles from the 90s about computer storage sizes and stuff. 100 GB/s is really fast now but in 20-30 years that's probably going to sound really dated.
It's dated already, that cable is 20 years old! - in the late 90's it could handle tens of thousands of connections but today it would be clogged by just a few hundred people trying to stream stuff from Netflix.
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 waited the entire video for Tom to mention the shark attacks these undersea cables have to withstand from time to time. Thought that'd be right up his alley.
2018: “High capacity cables that can transmit about 100 Gigabytes per second” 2020: “Australia broke the fastest internet record at 5.5 Terabytes per second!” What a long way we’ve come in two years, my god.
Tom could your next video be about Goonhillly it was a GCHQ station that was used to spy or gather SIGING from the Irish mobile phone network During the 1990’s. I think most GCHQ SIGINT is embedded in private ISP facilities posing as “something else”.
Porthcurno is my favourite beach in the UK (if not the world) but I really didn't know much about this although I had seen the cable hut. I hope you have a video planned about the Minack theatre up on the cliff sometime down the line
There is something odd about this video, besides Tom's Shirt having the compression treatment... It feels like the shutter speed was too fast... like generally it's 180 degrees or double the framerate but this looks too sharp, like there is no motion blur... hmmm...
It was shot at 50 fps so his target would be 1/100th, but if you're watching in a lower resolution TH-cam bumps it down to 25 fps. So it would still have the fast shutter speed but the slow framerate. That, or going out in the bright sun with no neutral density filters on hand, the camera needed to use a faster shutter speed to get the exposure correct and Tom accepted that rather than scrapping a video he clearly had to travel for over a filter. And let's be honest, he's said on multiple occasions that he goes for good enough on video rather than perfect and I'm personally fine with that, it looks fine.
Thanks to all the Telegraph Museum team: pull down the description for more about the museum and Porthcurno!

100gb per second is nothing it's 4000 homes with decent internet downloading a game of steam at 25mb/second

just out of curiosity was it 100 gigabytes a second or 100 gigabits a second as the terms are often referred to as the same.

He didn't say all of them are. He said most of them are.
The thing is, most of them AREN'T.
And what you are forgetting on your side are the cost and data capacity differences. Cables are going to be cheaper than to launch a whole fleet of satellite and the signal in a cable is re-amplify every 80 km to be able to carry that much data.
metropod Yes they are.

Google laid a 9000km cable for about $300 million. A Falcon 9 is about $60 million (less if you’re ok with a relaunched Rocket and they do offer a bulk discount) and can carry up to ten satellites per launch to low earth orbit. So you can launch a fleet of 50 satellites to LEO for about the same cost as 9,000Km of cable.
As the Falcon Block 5 comes into its own, each designed for 10 flights between refurbishments and theoretically 100 flights total, that cost will significantly drop.
The construction company I used to work for was massively behind on a government project. The media was coming to do a video walkthrough the building, so even though there were cables missing from sockets they still put the sockets on the wall to make it look finished... And then we went back to work the next day making the place a really finished :D
I hope you stopped at minack theatre round the corner Tom! Another fascinating story.
It's also one of the best Bass fishing beaches in the country when the tides are right
Amazing. Well done. Keep 'em coming.
I love that waddling seagull at 2:40
Wow i’m in Cornwall now, cool!
2:50 "Don't always believe in what you see on film... or youtube" so should I believe on this video?
If you have to ask...........
If you want to be reasonably sure of any fact, do some research on it. Enough for you to be sure of it.
Don't you mean sea on TH-cam?
3:19 reminds me of old videos/articles from the 90s about computer storage sizes and stuff. 100 GB/s is really fast now but in 20-30 years that's probably going to sound really dated.
It's dated already, that cable is 20 years old! - in the late 90's it could handle tens of thousands of connections but today it would be clogged by just a few hundred people trying to stream stuff from Netflix.
Neal Stephenson wrote an EXTENSIVE article about undersea cables for WIRED, and this place figures prominently.
The original telegraph cables and ships were amaaaaazing.
"dont always believe that you see on TV or youtube"
but this is on TH-cam, I'm so conflicted, Tom help.
I waited the entire video for Tom to mention the shark attacks these undersea cables have to withstand from time to time. Thought that'd be right up his alley.
Absolutely fascinating. You have done it again, Sir (one day?) Thomas Scott.
2018: “High capacity cables that can transmit about 100 Gigabytes per second”
2020: “Australia broke the fastest internet record at 5.5 Terabytes per second!”
What a long way we’ve come in two years, my god.
That's surprises me, Australia has shite internet
How cool. I had no idea the old cables were still used
Must visit museum really interesting and very well done!
I am assuming that you wouldn't make an elementary mistake, but you said 100GB/s, so the cable is ~800Gbps?
Tom could your next video be about Goonhillly it was a GCHQ station that was used to spy or gather SIGING from the Irish mobile phone network During the 1990’s. I think most GCHQ SIGINT is embedded in private ISP facilities posing as “something else”.
Porthcurno is my favourite beach in the UK (if not the world) but I really didn't know much about this although I had seen the cable hut. I hope you have a video planned about the Minack theatre up on the cliff sometime down the line
Wow that was very interesting. I will have to visit that museum when I’m in Cornwall next.
I've been there! It was a while ago so this was a mind refresher for me.
Well, I had no idea handling such a secret message from unknown person could be difficult especially without data leak
If you’d said you’d be in Cornwall, I’d have bought you a pint of Tribute.
There is something odd about this video, besides Tom's Shirt having the compression treatment... It feels like the shutter speed was too fast... like generally it's 180 degrees or double the framerate but this looks too sharp, like there is no motion blur... hmmm...
It was shot at 50 fps so his target would be 1/100th, but if you're watching in a lower resolution TH-cam bumps it down to 25 fps. So it would still have the fast shutter speed but the slow framerate. That, or going out in the bright sun with no neutral density filters on hand, the camera needed to use a faster shutter speed to get the exposure correct and Tom accepted that rather than scrapping a video he clearly had to travel for over a filter. And let's be honest, he's said on multiple occasions that he goes for good enough on video rather than perfect and I'm personally fine with that, it looks fine.
It's in 50fps. So the absolute shutter speed is relatively faster. Which I agree, does take a bit of getting used to.
that beach looks very smooth, i want to go there
Back then it was used in the war.
*RIGHT NOW it's used to slide into the DMs.*
