Over the past 48 hours, the Russian-speaking segment of the Internet has actively discussed accessibility and security issues. The main topic was the tightening of restrictions on access to Internet resources in Russia.
Users report interception of open DNS queries to CloudFlare and Google servers (1.1.1.1, 8.8.8.8) at the TSPU level. Technically, this looks like a substitution of the destination address to the NSDI server, which leads to NXDomain responses for blocked sites. TCP queries still work, and sending packets with low TTL can bypass interception. This is concerning as it affects ordinary users who use public DNS.
Additionally, there are problems with access to Wikipedia and GitHub: sites are partially or completely inaccessible without VPN. The reasons are not officially announced, but users associate this with regulator actions.
In the context of regulation, NAUFOR asked the Ministry of Digital Development to include services of professional stock market participants in "Cheburnet" so they continue to work during mobile Internet shutdowns in regions. This is important for retail investors who depend on access to brokerage services.
Separately, degradation of international traffic was discussed: connections establish but then speed drops sharply (e.g., from 80 Mbps to 8-12 Mbps). Also, cases of TLS certificate substitution (MITM) on Windows machines were recorded, indicating interception of secure connections. These phenomena need to be distinguished as they have different causes and consequences.
In browser security, Yandex launched a public program Yandex Browser Root Certificate Program, which allows certificate authorities to add their root certificates to the browser's store. This increases transparency and controllability of trust in certificates.
There were also articles on privacy: login via Google and incognito mode. It was analyzed what data a site receives during authorization via a provider, and why incognito does not protect against tracking, as sites use browser fingerprinting.
Overall, the main topic is the tightening of access restrictions and the need for users to adapt to new conditions.
