The main topic of the period is a massive Runet outage that occurred after an accident at Yandex's data center in the Ryazan region. Reports suggest it could have been caused by a drone attack. As a result, some of the company's services experienced disruptions, and then problems spread to dozens of major platforms: banks, telecom operators, government services, transport sites, social networks, and online cinemas. Users complained about inaccessibility of T-Bank, MTS, Russian Railways, VKontakte, Avito, and others. The outages even affected services that track outages. This shows how interconnected digital infrastructure is and how one accident can cause a cascading effect.
The second important story is the Cheburnet and substitution of Google DNS's main address (8.8.8.8). Users note that restrictions are being implemented on TSPU equipment and affect both mobile operators and wired providers. Unencrypted DNS queries are being substituted, and traffic is redirected to national resolvers. Encrypted protocols (DoH, DoT) still work for some, but there are concerns they could be restricted too. This is part of the Cheburnet policy — isolating the Russian internet segment.
It also became known that Xbox DNS was blocked for using a resource to bypass restrictions. Roskomnadzor, through TsMU SSOP, notified the owners about the presence of Cheburnet tools and blocked the service's subnets. The administration disabled some functions and stated it does not provide tools for Cheburnet. This is another example of the fight against Cheburnet.
For XConnect users, these events are important because they directly affect service availability and connection stability. Mass outages can affect any platform, and increased control over DNS and Cheburnet of Cheburnet tools make access to foreign resources more difficult. We recommend following updates and using reliable protection methods.
There is not much data for the period, so the digest is short. We will continue to monitor the situation.
