    If someone told me, just before the invasion, that in 2025 Ukraine would be dunking on Russian energy infrastructure with near impunity, I would have said they were batshit crazy. Slava Ukraini.

      At this point they’ve spent their entire Soviet inheritance. They foolishly demonstrated to everyone how poorly maintained everything was, from hardware to training.

      ~~Old school landline phones work without power. Not saying they’re using them, just a fun fact. ~~

      Edit: see below. I have no idea what in talking about.

        They absolutely do not. They just don’t require power locally, but there’s 48v on the line that needs to be generated somewhere.

          There will be a big battery bank in each telephone exchange that supplies power until the generators start up. I always hated the battery room, it smelled and there was always the danger of hydrogen buildup. The telephone exchange can keep running on generators until mains power comes back on, or the fuel runs out. (The longest outage I’ve experienced personally on generators was 3 days). The expectation is always that mains power will be restored “soon”.

            Battery backups and diesel generators at the interchange, both of which are only temporary. Batteries need to be charged and diesel needs to be pumped, and while you can (and most infrastructure resiliency relies on it) operate these systems on manual power, the stability of large infrastructure systems becomes quite vulnerable once it’s necessary to run a diesel generator to pump diesel for your other diesel generators.

            Because the phone company (miles away from you and your local power outage) still has power, or has battery backups and automatic generators. The phone runs off of 48v that is sent directly via the phone line. That’s why you don’t need to plug your landline into a power outlet. It was also historically a fairly important safety feature, as people tend to need emergency services after their power goes out. For instance, maybe a bad storm blew through.

            This actually turned out to be a problem when telecoms started transitioning towards digital phone lines. These days, they usually send everything via coax or fiber. Then a modem will take that incoming line and decode it into phone, internet, and TV signals. The modem also provides that 48v power on the phone lines. But that presents an issue, where a power outage will kill the customer’s modem, and therefore kill the customer’s landline phones. And we’ve already established that landline phones are an important safety fallback during emergencies. So now, you can actually get battery backups directly from the telecom, to be able to keep your modem powered (and thus use your landline phones) even during power outages.

              My house has a landline phone connected to the internet modem via a VoIP box. My entire house has battery backup so the modem, router, and phones stay on during a blackout, but the equipment my modem talks to (I’m assuming somewhere on the street) does not have a battery backup, so the phones are still useless in a blackout.

      Presumably it has a more direct affect on civilians, who are otherwise able to skip most of the consequences of the war. Russians going without heat over the winter will give a little taste of what they’ve inflicted on Ukraine and hopefully put some pressure on Putin. But it also affects manufacturing, both of war materials and civilian needs.

        And let’s not forget the commercials they were trying to ship to EU in the first year of war. The ones with Christmas without heating and food due to sanctions on Russia make EU collapse n

        And chances are these sorts of attacks will continue. That means less and less manufacturing capacity, etc.

    Great work Ukraine!

    Just be ready for a massive retaliation on your own power grid.
