If Russia follows through on this threat, it could have far-reaching consequences, effectively cutting the country off from the internet in the rest of the world – unless some sort of compromise is reached. LinkedIn, therefore, represents a sort of canary in the coal mine.

The company is currently in the process of being acquired by Microsoft for $26.2 billion, with the deal expected to complete by the end of this year. And the Russian government isn’t too keen on Microsoft, which it has accused of cooperating with the US government on surveillance.

More to the point, Microsoft software is widely used by Russian local and national government, and Vladimir Putin has made it his mission to replace as much of this as possible with home-grown products. This could be national pride; it could be an attempt to boost local businesses; or, like the data localization ruling, it could be an attempt to make surveillance easier.

At the same time as banning LinkedIn, Russia’s antitrust regulator, the Federal Anti-Monopoly Service, has announced an investigation into Microsoft. It’s accusing it of abusing its power by giving anti-virus developers too little time to adapt their products for Windows 10: just a few days, rather than the two months that had previously been standard.
