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.
