In recent years they have been trying to build a nation-wide Intranet that can function while international gateways are blocked. It is not perfect and every time they block the Internet, many issues happen but for the most port critical network services (such as payments) continue to function.

Seems like it would be an easy target for the government (or really anyone) to DOS, right? Presumably there's no good way for the nation-wide intranet to exclude government actors? I'm just thinking out loud; I'm glad to hear something is being done and I wish the Iranian people the best.
