Internet Backbone

John Rain · 2022-09-04 07:51
How many points of failure does the Internet Backbone have? Does it differ from place to place? How likely would it be to disconnect an entire country from the internet by attacking the Internet Backbone? How about "attacking" it physically - meaning literally cutting the cables. I know... the cables connecting Europe to America are under the ocean, but how about the cables connecting European countries to each other? I'm sure that countries like Germany have many backup cables just to be safe, but how about poopholes like Ukraine? Would it be possible to disconnect Ukraine from the internet by cutting few cables? Their infrastructure is probably pretty bad (as everything in that country), so it shouldn't be too hard to cut them off the internet completely.

There are only a few points where undersea cabels go through countries, reminder that Somalia lost internet when a captain accidently dragged his anchor across a line

>>20041 Well, if the picture is correct, then I should be able to disconnect Ukraine from the Internet by cutting two different cables, one in Poland and one in Hungary.

>>20042 that's not the whole internet backbone, it looks like it is the map of one tier 3 provider's backbone. Another map I found (infrapedia.com) has two other connections. >How many points of failure does the Internet Backbone have? It depends a lot on the country. The US, Hong Kong, and Taiwan all have hundreds of cables going in and out, while many countries have one or zero. The internet backbone as a whole probably couldn't die completely under normal circumstances, although a big solar flare could easily put it in a lockup state that might not be reparable.

Really? Interesting. How about EMP caused by detonating nuclear bombs in space? Would that have similar effect?

> How about EMP caused by detonating nuclear bombs in space? Its really hard to say, since not many tests of the HEMP effect have been carried out and the data we have is not very good. Some old Soviet sources say they had the capacity to take out kilometers of buried electric cables, while some other sources say its really nothing to worry about.

>>20048 >>20049 >Really? Interesting. How about EMP caused by detonating nuclear bombs in space? Would that have similar effect? HEMP tests are literally derezzed because they fuarrrk up things in space too, IIRC one test took out over 20% of satellites in space at the time. HEMP is only a concern when you don't see it coming, there are a lot of failsafes in place for when you do see it coming. If you want to know where cables are, just look at nautical charts, they literally have big lines that say "undersea cable" with the assumption you aren't going to put your anchor there https://data.noaa.gov/dataset/dataset/submarine-cable-areas1 Funny enough while looking for a picrel, I found this article about how vulerable they are https://www.wired.com/2015/10/undersea-cable-maps/

>>20040 >How many points of failure does the Internet Backbone have? There is no single Internet backbone. Every ISP has his own backbone. The image you linked just shows the European PoPs of Arelion, better known as Telia (AS1299), a Tier 1 provider. >Does it differ from place to place? It differs from place to place and especially form ISP to ISP. >cables connecting European countries to each other? There are a lot of cables between each country and even the infrapedia only shows a small part of that. e.g. i couldn't find a single Deutsche Telekom or other former state monopoly ISP cables on the map and they have a lot for sure. On the contrary it's hard to tell exactly how resilient those connections are because even two different physical cables can share the same trench and ISPs often only rent layer 2 connections between two points so you don't really know how the cable physically connects those places. And you may have 20 ISPs that have a connection from A to B but all are using the same physical cable.
