The biggest glitch in RuNet is that sites with the .ru domain are unavailable

Internet users report problems accessing Russian websites. Yandex websites, a number of news portals, banking applications, taxis and deliveries do not work. Clients of all major Russian operators, as well as compatriots abroad, for example, in Europe and Armenia, complain about problems with access.

In specialized communities they write that the failure may be associated with DNSSEC (Domain Name System Security Extensions) - this protocol is used to increase the security of sites. For example, to prevent attackers from replacing data or a site’s IP address.

UPD: The Ministry of Digital Development also confirmed a failure due to DNSSEC - they promise to restore access to .ru sites “in the near future.”
