 Hey guys, welcome back to my YouTube channel. This is Daniel Rosal here, and I'm having a bad internet day I'm having a bad internet day today, which has actually been already very disruptive to my business despite my lovely fail-over internet setup The cellular is a little bit tricky to work with when there's a bunch of people at home Drone band with office, and I'm having this bad internet day because there is a nationwide internet problem today in Israel The partner internet service provider ISP is having its problem And why is partner having a problem partners having a problem because of a internet cable? It's the med nautilus internet cable which links between Israel and some other places in the Mediterranean actually goes over to Italy Now most people have never heard of this really fascinating World of the submarine internet cables and there's a fantastic website the one I'm currently on now It's called submarine cable map calm. I will put a link to the description But I'm also going to go low-tech here and just type it out for you submarine cable map calm It's a fantastic resource free and regularly updated resource by telegeography and on this web page You can literally see the cables now. What are the cables? Well, did you ever ask yourself when you connect to the internet and Tel Aviv or Jerusalem or a lot? How do you actually get data from a server in Los Angeles, right? How does that work exactly and the answer is that the internet backbone which is the main Part of the internet is actually connected mostly through Oceanic cables are literally cables running at the bottom of the ocean beds laid by special ships It's pretty freaking amazing for those interested in going down this rabbit hole further. There is an amazing YouTube video You'll actually see what these cables look like and the interview the guy who manages one of these landing points And these are these are what are called landing points where the cables hit onto land and you can see they're on the periphery of these Continent so the interview some one of these guys. I think he's in Denmark And these cable landing sites are naturally very very sensitive, right? I mean if you think about the potential for espionage or anything like that if you were determined to do that on a Big-scale well, you'd probably want to tap the top of the system, right? So these landing sites are actually super sensitive even though they just in reality look like a little house on the beach With some protection and the interview the guy in Denmark and he holds up with his hands The internet cable supplying Denmark and it's literally like an ethernet cable. It's absolutely incredible The amount of data that can actually be carried in a small fiber optic core is pretty mind-blowing So yeah, go down that rabbit hole on YouTube. You have my encouragement. Let's look at Israel's Links just to show you how the internet works in Israel. So here is Israel It's a small country and you can click on one of these cables and you can actually see So this is the reason if you are not having internet today like me Because of partner the problems here. It's the med nautilus Submarine cable system in green and it lands in Haifa And it also lands in Tel Aviv in Tel Aviv. I know it's on Gordon Beach. I have no idea where it lands on Haifa So these are the cables we have currently you can see there's the med nautilus submarine system now until fairly recently This was the only game in town They had a monopoly and if we trace the path of med nautilus and it's the green line on the right here If I'm not mistaken We should see it meandering its way up to Italy or if you follow one of these links, right? You can see this Gray line here originating from Italy goes down. It's a bit harder to keep track of these But this is Jonah and we can literally attempt to trace it. Let's try to do that again med nautilus med nautilus med nautilus Yeah, med nautilus then bifurcates and lands in Greece and Then there's another chain of med nautilus that feeds up in Bulgaria into something called the kafos cable So anyway, if you want all the details, you can find them out here There's actually some med nautilus used to be the only one it's operated by a irish company But they have italian headquarters or something like this Then bezek built their own cable called tamar is north and this as you can see connects up to cyprus And then from cyprus it feeds in so this is like a worldwide This is now it's not exactly true that if you connect to a website in Let's say you watch a youtube video that it's coming all the way from a server in wherever youtube hosts data. Let's say Let's just say last angeles How the internet works nowadays is a little more sophisticated It's something like youtube or assets that a lot of people are watching well It doesn't make sense that every single time there should be data going back and forth from Israel to the world So major data providers will cash Commonly viewed assets in edge locations. There might be like a youtube server physically in israel And that if you're watching or streaming a popular youtube video or a netflix show, it's actually coming locally But ultimately at some point that data might be propagated to that server From the us and how does it get from the us to israel? Well at the speed of light it literally travels along the ocean bed on one of these cables Maybe makes a switch here a switch here a switch here a switch here until We eventually get here and that's why when the men not tedious cable breaks down If you're sitting in a lat right well There's two ways you might use internet one might be that a digger outside your front door Rips through the internet cabling right that 500 meters from your door or If you're living in jerusalem, it could be the case that there was a Ocean vessel here off the coast of Crete that literally sliced through the cabling a thousand miles away So it's actually fascinating how interconnected the internet is and I just to finish off so we looked at the tamarace and the Mednautileus systems and then in Tel Aviv we have a few different branches actually there is lev submarine system another mednautileus jonah And uh blue and then in a lat we have a couple more as I can't zoom in any further in tab there's a landing point and in uh raman there is a landing point and uh You can get some details about it. You can see it's got its id Who is own who it's owned by in this case? It's a consortium of companies that can't be the one because it's not listing lots of landing point But if we go on to the mednautileus System this website's a little bit finicky mednautileus here And we can see it's a 7 000 kilometer cable operated by telecom italia And besides hypha it also lands in istanbul catania italy And as we hover it showing the landing points tel Aviv hypha chania in greece athens in greece pen taskinos in cyprus and uh you can find out about the cable by going on to the cable's website And they will give you even more info about that particular cable Final thing to point out here is that there is another cable coming Google has announced plans for an undersea cable connecting israel southern europe and it's going to be tying israel So this is actually a kind of crazy dynamic that we've been seeing in recent years Traditionally there were only a few cables operated by major major telecom consortia And in recent years we're seeing big tech like google and amazon aws Actually laying their own trans and trans oceana cables, which when you think about it, it's pretty extraordinary So this is an example of the development like this It's going to be called the blue submarine cable system and it's going to connect israel italy france and greece The other is the raman the submarine cable system will connect jordan I think we saw that on the map just there and according to the last report i read about this This is expected to become operational in 2024 And the more cables that are laid here we go Yeah, the company expects cables for use in 2024 the more cables that are laid and the newer cables can carry more data So the more bandwidth becomes available to domestic internet consumers it all flows down So when you're looking at your internet options in israel people tend to look at their local isp and There's a whole bigger picture going on in the background And that's the submarine cable system that actually forms the internet backbone And basically what connectivity is available to to israel at the level of the international switches here To the international internet system. That's kind of the choke point for what domestic isps can offer So I hope this this deep dive into the very random But I think fascinating subject of submarine cables was interesting And if you want to get more videos from me about this and lots of other very random tech topics Please subscribe to this youtube channel. Have a great day
