The technicalities of such an order greatly interest me — Roskomnadzor already has statutory rules in place that make ISPs block egress traffic to proxies, Tor entry nodes, and similar. Since the censorship infrastructure is already there, couldn’t they similarly not put up stateful firewall rules to prevent any inbound connections from outside Russia?
Lots of Ukrainians live and study in Russia even after the war (I knew a Ukrainian citizen who was studying at PhysTech despite the 2022 war), and lots of families in Russia have relatives in Ukraine (and vice versa).
It makes this war even more tragic, because Ukraine and Russia are so intertwined socially and culturally, and there was no reason for Russia to escalate the war.
That said, Roskomnadzor can't fully lock down ingress and egress without drastically impacting the Russian economy and pissing off your average Russian who watches YouTube, games on Steam, and messages using Telegram.
Back in 2021 Russia did several tests that disconnected from the international internet. They were prepared to do that and they didn’t suffer much financially and nobody really noticed tbh https://www.reuters.com/technology/russia-disconnected-globa...
