Yandex says Vladimir data centre shut down after drone attack

Yandex's data centre in Vladimir stopped operating completely after a drone attack, according to Russian reports published on October 11. Kommersant quoted the company saying no one had been injured and specialist services were already at the site addressing the consequences. Yandex said its team was assessing the damage and possible plans for restarting operations. RBC also reported the complete shutdown after an attack and said the company recommended that users activate alternative disaster-recovery plans. [ 1 , 2 ]

The incident involved power-supply problems affecting the ru-central1-a availability zone of the Yandex Cloud platform, Kommersant reported. It said the cause was not identified when the power problems were initially reported. The outlet's article was updated at 05:32 to include information about the cause. Kommersant also reported that complaints about Yandex Go, Yandex Music, Yandex Pay and other company services increased in the morning. Habr's summary likewise described problems with Yandex Cloud and several consumer services, alongside reports from local residents of explosions and a fire. [ 1 , 4 ]

The sources differed in how definitively they described the cause. Kommersant and RBC reported a drone attack, and TASS's headline also linked the shutdown to an attack. Habr referred to a probable attack and said a comprehensive official explanation of the causes and extent of damage was not available when its material was prepared. The reports also placed the Vladimir shutdown alongside earlier incidents involving Yandex infrastructure in Sasovo, Ryazan region, and Kaluga. Kommersant said those data centres were attacked on October 8 and 9, and that a fire had completely halted operations at Sasovo. [ 1 , 2 , 3 , 4 ]
