Как технически устроена DPI-фильтрация у российских провайдеров и как её детектировать: разбор open-source инструментов

В последние пару лет любой пользователь рунета научился различать “интернет дома” и “интернет в гостях у бабушки”. На одном провайдере YouTube открывается, на другом нет. Это ощущается как непредсказуемость, но за каждой такой деградацией стоят вполне конкретные технические механизмы. Запустил open-source инструмент dpi-checkers на трёх своих подключениях, разобрался с методами TCP 16-20 и CIDR-вайтлистами и расскажу, что технически происходит с вашим трафиком на L4 — от SNI-фильтрации до QUIC-блокировок.

Pizza! An charming article about pizza from the October 1949 issue of The Atlantic thanks to gift article bot @GiftArticles

“In a world of ready-made food, packaged to be tossed together by amateurs, pizza stands apart—one dish, at least, which calls for time and skill.”

With a photo of a pizza I made last Sunday in my Ooni pizza oven that I love so much

‼️ Russia blocked Bluesky
https://explorer.ooni.org/findings/287571208700

As of 11th April 2026, OONI data shows that access to @bsky.app is blocked on multiple networks in #Russia.

On some networks, the block is implemented by means of DNS tampering and automatically confirmed. On most networks, the block is implemented by means of TLS interference.

This follows the blocking of Telegram, Signal, WhatsApp, Instagram, Facebook, Twitter/X, and many other platforms.

We’re thrilled to host Sadia Nourin as an OTF Information Controls Research Fellow! 😍🥳

Her work will measure transit censorship worldwide -- using IPv4/IPv6 measurements and extending OONI Probe to pinpoint where censorship occurs on the network path. 🐙

OONI data suggests that many ISPs in Russia began blocking access to Telegram on 20 March 2026.

This follows blocks of other major services, including WhatsApp, Signal, Instagram, and numerous independent news outlets.
