Usually, the circuit for connectivity and the other costs,  are bundled 
by the ISP/bandwidth-carrier. Sure it get's more complicated with 
bypass, dark-fiber, IEC, and a myriad of other vendor solutions.

Comm gear is usually low power, but if they assign you a rack or 
whatever, then the accounting can tag you with hundreds per month for 
Air Conditioning, transport, etc etc.  So I was not intending to go down 
that pathway of charges and fees.

yep, at least (2) static IPs. Once running I'll find a similar bandwidth 
usage organization and swap DNS secondary services. Now days with all 
the issue wit CA  and others similar/related issues. that might get 
complicated. (2) static IPs for (2) dns primary resolvers should get me 
going.

I agree, based on what you have shared.

Well, it's probable not appropriate for me to "finger" specifics. But if 
you just learn about all the things some carriers are experimenting 
with, in the name of 5G, it is a wide variety experimentation, to put it 
mildly.

"Some" folks would argue the mess with Certificate Authority (CA) 
provides an enormous venue for Nefarious activities. Some would say "the 
feds & company" would/are choosing  instability, rather than enforceable 
rules, which include the (US) federal authorities. Their default is 
"hack the planet", as long as we get backdoors and other forms of access 
to everything.

  However this list has many very smart readers. I'm not going too deep. 
I will say that every RF chipset is deeply comprised and it takes 
millions of dollars in gear to delineate that. Believe what you want.

But someone like you (Grant) could help guide and document a gentoo 
centric collective that provides for
email services, secure/limited web servers and a pair of embedded/DNS 
(primary) resolvers so we can keep email systems alive. With that 
baseline, folks with a need, can add what they want. That's what I'm 
trying to achieve. Common interest that eventually also leads to a very 
robust testing semantic. Web, Email, and DNS services is a very large 
effort, particular with robust and routine security testing.

There is another movement to put linux, source base, onto your "open" 
cell phone, but that's another thread for another day.  2 projects 
(gentoo centric) in estimation, destine to become robust and as 
critically important, as the Linux kernel itself.

Personally, I strongly dislike all of those replacement services, from 
megalopolis like Google, Facebook, Microsoft and others. ymmv.

  Thanks  for your insight and suggestions.
