SDF Public Access Unix System

Would this be of any help?

See https://en.wikipedia.org/wiki/SDF_Public_Access_Unix_System

I’m a member there, and could have asked to get outernet a free account with all of the perks (they do this for educators), they’re a non profit, and have a lot of Unix folk about, as well as Hams - it’s very stable and has been around for 25 years.

It could have been a handy place to host some ancillary services - for example as a staging area for my SMS-BBS idea…

Not sure what the overlap with outernet might be but I do second SDF-1 as great system/service/place for nerds like us.
