I wonder how they backup the cell towers and how long the will stay up
without the power lines.

You ever notice those little "dog houses" that sit beside the tower? It
houses a generator. Usually powered by natural gas so it's fuel supply is
virtually limitless.

While we're on the subject of 'juice' so to speak, in every power outage
up here in the north country [upstate NY] the phones are mercifully
still much welcomed operation but, here's the thing, while it's common
knowledge that the phone system wires carry their own juice, well, even
those wires have to have a source for their power generation! Where is
it and note that even in extensive power grid failures like the nation
just experienced, the phones came through! So where is their source? Or
does the phone system commonly LOW DC voltage and thus absence of any
needed AC 'push' amperage [dunno, I'm asking!] permit a DC generator
system that can virtually run with no problems!? Any phone techs in the
house?

Of note...I have an ARO [amateur radio operator] amigo in Russia and we
converse doing the low power and rig/computer assisted RTTY [radio
teletype] thing and he believes it's utterly 'amazing' that Americans
and canadians have such 'up time' telephone and power generation systems
[despite the occasional grid foul-ups and assorted local woes ] where he
says in Russia it is a literal 'treat' to get uninterrupted phone and
power service for more than a few 'days' without one or both failing or
in fact being shut off [!] for one reason or another ...yet the attitude
there is 'so what else is new' where here [USA/Canada] it's good for
talk show circuit and blame mongering fodder ..... for days!
