So there its not just a firewall when crossing the border? There is some internal filtering going on as well? Or is it more of the case that Iran lacks domestic infrastructure and the international cutoff just broke a lot of basic services (like dns) because they were rellying on foreign services,apis...etc and thats why there are internal issues? It would be great if some of your friends could give a better overview of this. Do you maybe know if the keet app works in iran? (keet.io)
