It works, but only some of the time now. It’s been very unstable for me since the outage started. I’m in Spain.

replyAll essential infrastructure has to. Heck, if you have a landline you can probably siphon off some power from the DC component.
Cell towers have backup generators?
replyWe had a (much smaller) regional (Lübeck and Ostholstein) power outage here in Northern Germany in I think 2018 or 19. No mobile internet until everything was restored ~6 hours later, and most of the time no other cell service either.
replyMost of them have batteries. How long they last depends, in my country they can typically manage 4 hours.
replyBatteries at least.
replyThey still need other infrastructure to get anywhere though (routers and other networking infrastructure).
replyCell towers have batteries and/or generators, with fibre connections to data centres, which also generally have batteries and/or generators.
replyAlways picture someone with a big can of diesel filling up a generator. Experience says it could be a genny running on natural gas. Had that at work before.
replyI think cell phone towers use surprisingly little energy, just a few kW. So even longer term operation should be possible withs bobs backyard generator running on vodka.
replyBut I would guess the whole network equipment would draw quite a bit, especially a modern infrastructure.
