Russian ISPs have been throttling internet connections to Cloudflare-protected websites since June 9, 2025, limiting data transfer to only 16 KB per connection. This effectively renders most web navigation impossible for Russian users. The throttling affects all connection protocols including HTTP/1.1, HTTP/2, and HTTP/3, and is implemented through various mechanisms like packet injection and connection blocking. Multiple ISPs including Rostelecom, Megafon, and MTS are participating in these restrictions, which appear to be part of Russia's broader effort to isolate its internet infrastructure from Western technology providers.
