No casualties were reported in the Vladimir attack. Users across Russia, including Siberia, reported problems with Yandex Go, Yandex Pay, Yandex Food, Yandex Pro, Alice and other services.
Some customers were unable to book taxis or order deliveries. Yandex Cloud users were advised to use alternative contingency arrangements for data storage.
In a press office statement addressing the earlier attacks, Yandex said its Sasovo data centre was seriously damaged overnight on 7–8 October and completely shut down. The company also confirmed that an attack on its Kaluga facility left part of its infrastructure out of service.
Yandex said no employees were injured at either Sasovo or Kaluga. Emergency services and company specialists were working at both sites.
“Our teams are working day and night to do everything possible to keep services running and to help those affected by the incident,” the press office said. “Right now this is our most important task, but unfortunately it is not an easy one.”
Yandex said millions of people rely on its services for navigation, entertainment, grocery orders and information. It also said hundreds of thousands of companies use its technology to take orders, serve customers and work with partners.
“We are continuing to assess the condition of our infrastructure,” the company said. “For now, it is very difficult to say when the equipment at the data centers will be back up and running.”
Vladimir region governor Aleksandr Avdeyev said the latest attack destroyed two substations supplying electricity to 5,000 residents. People living near the attack site were evacuated.
Avdeyev said electricity supply had been restored to 80% within an hour. Heating and water services were fully restored.
Russia’s Defence Ministry said its air defences shot down 479 Ukrainian drones overnight across 17 Russian regions and Crimea. That figure covered the wider overnight attacks.
Sasovo houses Chervonenkis and Lyapunov, two of Yandex’s three supercomputers. The third, Galushkin, is located in Vladimir, and information about the condition of the three systems was unavailable.
