An attempt by the ILV to "slow down" communication with Twitter resulted in local "Internet cataclysms"Unfortunately, any useful technical information on how exactly ILV decided to implement the what publicly stated, not so much. You can even say that it practically does not exist. So it remains only to speculate on the observations and available data.
From the observations at the moment, we have: scattered "local" messages that twitter really slowly opens (or does not open at all). Moreover, it seems that most of them concern a mobile application.
At the same time, at the same time, even through Rostelecom (by wire), Twitter itself opens quickly, and so does the video from its CDN.
Providers of the Russian Federation, for the most part, use the systems of deep traffic analysis (DPI, Deep Packet Inspection) to block sites included in the register of banned. There is no single standard for DPI, there is a large number of implementations from different DPI providers that differ in the type of connection and type of work.
There are two common types of DPI connection: passive and active.
