Mid year 2018, maybe it was 2019, there was a massive internet outage. Closest guesstimate to the causes was a truck with their boom up ran through an intersection clipping fiber and power lines, and a fiber bundle was accidentally cut in a separate incident, this was all state side. Internet went down for nearly every ISP, services dead, country wide it was found we don’t have redundancy like we thought. You see, when internet lines are built out, the lines are divided up to different owners and leases, those third parties sell backup internet services to major isp’s, but no one was checking if the backup was running across the same infrastructure at any point, sales was selling, and the backup lines worked and we never had a full bundle break previously that was carrying main and backup bundles. When this outage happened, it hit Russia as well. Russia had an internet outage because of 2 bunlde breaks in the US. This tells me they are linked to the US network, and might infact be capable of doing multiple nefarious activities that made use of the wide open hole we had in our infrastructure. Now I don’t know if our infrastructure was patched, they kept that above most peoples pay grade. But the weakness was there, and it was on display to the entire world plain as day. They could either poison our networks/DNS/routing tables/etc with their high-speed connections, or just use it as a heartbeat to see the success of internet based attacks.
