This actually scratches an itch I've had on and off over the years. Over a decade ago, I remember reading a Quora post along the lines of 'How does ISIS still have internet? Who maintains the infrastructure?', and the only response was from an alleged ISIS propagandist (or an internet troll) with vagueries about the reach of ISIS, and that they couldn't answer for "security reasons".
That question lived in my head on and off throughout college, and I'm glad to have gotten a bit closer to understanding the reality of what was happening on the ground.
