2019/03/21: In the next two weeks, Russia is planning to attempt something no other country has tried before. It’s going to test whether it can disconnect from the rest of the world electronically while keeping the internet running for its citizens. This means it will have to reroute all its data internally, rather than relying on servers abroad.
The test is key to a proposed “sovereign internet” law currently working its way through Russia’s government. It looks likely to be eventually voted through and signed into law by President Vladimir Putin, though it has stalled in parliament for now.
Pulling an iron curtain down over the internet is a simple idea, but don’t be fooled: it’s a fiendishly difficult technical challenge to get right. It is also going to be very expensive.
As well as rerouting its ISPs, Russia will also have to unplug from the global domain name system (DNS) so traffic cannot be rerouted through any exchange points that are not inside Russia.
“An alternate DNS can be used to create an alternate reality for the majority of Russian internet users,”
