In the morning on the 31st of January a part of domain names of Runet appeared to be not delegated, that is not adhered to DNS-server which defines what domain corresponds to what IP-address. Malfunctions started because of the failure in RU-Center - the largest, actually exclusive national registrar of domains. There are, of course, in the Russian Federation other registrars but RU-Center is actual "daughter" of RosNIIROS which began at the state level registration of domains in Russia but two-three years ago completely transferred business of the company to RU-Center, which was initially created at RosNIIROS.
