&gt; preemptively finding such proxies and jumping between them<p>This is why it is so important to create <i>protocols</i> for communication instead of single-point-of-failure services. While it is still possible for bad actors to interfere with traffic, it is <i>much</i> harder to shutdown an entire network of federated servers. In contrast, a service can be disabled by simply throwing legal papers at the person running the service (or otherwise threaten them, bribe them, etc).<p>&gt; DPI could drop packets containing emails addressed<p>Which is why that email should have been encrypted. Even non-authenticated opportunistic encryption would make that kind of DPI much harder and more expensive.<p>We&#x27;ve had encryption for a long time, and there is absolutely no excuse for to not have encryption in all network software. Unfortunately, a lot of software has been badly negligent in their duty to keep their users safe.<p>&gt; cuts off the country&#x27;s Internet access entirely<p>...they should be left with a split network, still able to communicate internally.  It is pure hubris to believe that a single service will always be available in any situation; when international links are involved, some amount of loss-of-service should be assumed. This is why email allows multiple MX records - servers fail, so build in backups, some of which can be local.<p>&gt; peer-to-peer stuff<p>Yes, though the model to copy is <i>federated</i> services like email.<p>The power of the internet is that it IS peer-to-peer. No 3rd party has to grant authorization to listen(2) for connections or connect(2) to a remove host. This has been forgotten because of the damage that NAT does to the network (you aren&#x27;t a full citizen (&quot;peer&quot;) on the internet when you have to ask the NAT device to forward your packets.)<p>Now, after about a decade of failing to heed the warnings about NAT, the digital imprimatur[1] is being constructed and running proper peer to peer (no 23rd party) is harder than ever. Hopefully IPv6 can reverse this trend.<p>[1] <a href="https:&#x2F;&#x2F;www.fourmilab.ch&#x2F;documents&#x2F;digital-imprimatur&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.fourmilab.ch&#x2F;documents&#x2F;digital-imprimatur&#x2F;</a>
