I found the premise of this article [0], that throttling connections
(based on SNI) is new, a little amusing. It reminds me of how Iran
implemented a very similar technique almost a decade ago [1]. I don't
know of earlier uses of throttling as a censorship mechanism, at this
scale, before the early-2010's (but I'd be interested in learning about
them, if anyone knows).

An earlier article about Roskomnadzor's implementation is interesting
[2], for those who missed it.
