I saw https://academy.afrinic.net/ posted on another site. It looks interesting, but ... firstly, I'm not in a job where this is directly applicable. When I'm standing up a facility (which is less and less these days, as there's now a special team which usually travels out to take care of this), the ISP technician hands over a fully functional high speed public Internet connection and we take it from there. Except, again, the special team does it, as only they are allowed to handle and program certain equipment.

Secondly, I don't think I have the raw mental capacity to do all the things I already feel the need to study in preparation for job.next(), so adding another isn't happening.
