    “fiber will be much more safe than relying on sats”

    Spoken like someone who has never had some idiot in a backhoe chop a fiber bundle…multiple times in a week.

    We have a saying in IT. Always carry a 1ft section of single-mode fiberoptic when hiking. If you ever get lost, just bury that sucker and some dipshit in a backhoe will be out there in a hour to cut it in half.

      And, when it happens, it generally gets repaired in hours. You cannot launch a new constellation in hours.

        True, but your’re comparing a single fiber optic line to an entire network of satellites. Blow up one, and they simply route traffic around it. Blow up 10, and you might have a small moving deadzone that removes service for a few minutes.

        If you want to compare accurately, look at the time it takes to replace the cable infrastructure for an entire nation vs the time it takes to relaunch all the star link satellites. We started using satellites in the first place because it was the fastest (and in many cases, cheapest) way to get TV coverage anywhere on the planet.

          You understand EMPs wouldn’t affect one sat, right? Or a capture net can hit an entire train?

          If you want to compare accurately, look at the time it takes to replace the cable infrastructure for an entire nation vs the time it takes to relaunch all the star link satellites.

          That can, and has been done in a couple of weeks. It happens somewhat regularly.

          https://www.leadventgrp.com/blog/submarine-cable-damage-and-repair-claims-and-remedial-measures

          10-20 days to launch a repair crew, and another week to affect the repair. At a few hundred million in costs.

          A single rocket launch it minimally a year of planning. And BILLIONS in costs.

          We started using satellites in the first place because it was the fastest (and in many cases, cheapest) way to get TV coverage anywhere on the planet.

          Well, yes, because they are placed in a high orbit (Not LEO) generally, in order to cover massive patterns with ONE WAY signalling (Aside from the one uplink).

          This is a host of difference between myriad 2-way ground stations.

              Whoops, there you go again comparing the impact and resolution of a single cable to an entire national network.

              That’s… um… how it works? It’s generally one, maybe two, cables connecting continents: https://dabrownstein.com/2015/06/30/charting-interconnectedness-in-undersea-internet-cables/

              I mean, some continents, like the US, have myriad cables connecting. And purposefully sabotaging these is almost as challenging as repairing them.

              So, generally, “nations” are not connected via undersea cables, continents are.

              So, yes, repairing one, maybe two, would be reconnecting an entire national network. Which is STILL cheaper than replacing a mass of Starlink sats… Which, btw, need replacing routinely anyways, because their orbits decay purposefully.

              So, every 5 years, we need spend tens of billions to launch another set of trains, just to have them fall into the ocean after 5 years of service. Just to obtain a service that is cheaper, and doesn’t require nearly as much regular investment if we just used fiber.

              https://www.space.com/spacex-starlink-satellites.html

              I get the feeling you don’t understand the economics, physics, and infrastructure of various connectivity systems. And, you also don’t understand that without connected ground stations, served by those “at risk fiber networks on the ground” (That you purport as very risky), Starlink doesn’t work, either.

                You are comparing a backbone to last mile? Starlink relies on that fiber backbone too. Cutting all the last mile fiber in America would be an insanely difficult attack. Satellites are comparatively vulnerable to a great many attacks. They literally fly over the enemy.

                I think you didn’t quite understand. I’m not talking about just undersea cables. An accurate comparison for the impact of blowing up the entire Starlink constellation would be to remove ALL the fiber optic cables in an entire nation, not just the undersea cables. That is a more accurate comparison.

                I may not have an expert level of economic knowledge, but the fact that Starlink exists and it can provide better service than rural broadband programs or the extensive terrestrial mobile broadband networks (which still use satellites BTW) is a pretty good indicator that it is viable.

                Frankly this entire statement is insulting, and you should retract it.

                  Oh, so you mean a very viable attack today (Taking out swaths of constellations) is on par with destroying a sizeable segment of a web of fiber that is very interconnected, and very resilient to outages due to a single fiber?

                  I may not have an expert level of economic knowledge, but the fact that Starlink exists and it can provide better service than rural broadband programs or the extensive terrestrial mobile broadband networks (which still use satellites BTW) is a pretty good indicator that it is viable.

                  It’s viable because we are funding that, with gobs of money, instead of using those gobs of money to fund something that is “Buy once, cry once” instead of Starlinks “must be replaced in total, every 5 years, at billions per train”.

                  Frankly this entire statement is insulting, and you should retract it.

                  No, and frankly, you’re digging yourself into a deeper hole.

                    Alright. Let’s clear this up.

                    Are satellite links easier to take down than a fiber link? No. It takes specialized weapons manfactured by state level actors to take out a a single satellite, let alone a whole constellation. I can take a pair of wire clippers, and take out every cable link in my neighborhood in a afternoon. Russia fairly regularly sabotages undersea cables just by “accidentally” dragging an anchor over them.

                    Is Starlink funded partially by public money? Absolutely yes, along with every other telecom provider. Hell, we gave them the public TV bands as compensation for builfijg a public fiber network (which they never even fucking did!)

                    Do Starlink satellite need to be replaced at extreme cost? Yes, but so does terresrrial network infrastructure. There is a reason why your internet isn’t 12kbps anymore… As far as the cost goes, the consumers determine if the cost is worth the benefit, and so far the answer is ‘yes’.

                    Ever wonder why Ukraine was using Starlink for network connections in the first place? Maybe it’s becuse the vulnerable terrestrial based networks were damaged or taken out of service months ago, and you can’t exactly get a contractor to go into a warzone and lay down new cables.

                    Your points, that satellites based networks are more vulnerable and prohibitively expensive is simply not compatible with reality.

        Nope. But I think it would faster and easier to replace all fiber with Starlink than it would to replace all fiber with fiber again.

              I’m just trying to understand why this argument is even happening.

              You seem to basically agree with them. What’s even the point?

                It is simply harder to sabotage if the wires are underground and cannot be readily seen by hostile actors.

                This statement is not correct. It is the topic being discussed. Fiber network are more vulnerable than satellite networks. It takes specialized weapons to take out a single satellite link. Any idiot with wire clippers can take out a fiber link, and it happens all the time. Fiber networks are more difficult to replace at scale than a satellite network, and individuals links are more important to fiber network than they are to satellite networks.

                  The thread topic is SpaceX saying we should dump all fiber plans and go with Starlink.

                  I had to clarify what you were arguing about, because otherwise I was going to yell at you about latency issues and data throttling and the risks of Kessler syndrome and about how bad it is to put critical infrastructure in the hands of a single company.

                    I’m well aware of those issues as well, which is why I’m not pro-starlink replacing all terrestrial networks.
