A Ukrainian drone strike targeted a major Yandex data center in the Russian city of Vladimir early Sunday morning, Oct. 11, forcing the facility to suspend operations and causing widespread disruption across more than 80 digital services and cloud infrastructure components.
According to ASTRA and Crimean Wind Telegram channels, the attack on the 40-to-50-megawatt facility in Vladimir’s Energetik district marks the third precision strike on Yandex server infrastructure in four days.

The facility, designed to house up to 2,880 server racks, represents one of the Russian tech company’s foundational processing hubs.
Following the explosions, Yandex confirmed that operations at the Vladimir data center were halted. The disruption cascaded through Russian digital infrastructure, affecting consumer applications including the Alice voice assistant, Yandex Music, the Telemost videoconferencing tool, and Yandex Smart Home.
Enterprise systems hosted on Yandex Cloud suffered extensive outages across computing, storage, database management, and development pipelines.
Disrupted services included Compute Cloud, Object Storage, Managed Kubernetes, PostgreSQL, and ClickHouse databases, alongside developer tools and artificial intelligence interfaces such as the YandexGPT API, SpeechKit, and Vision OCR.
The outages extended beyond core Yandex applications, affecting third-party commercial platforms across Russia and neighboring countries. Users reported connectivity failures in banking applications, ride-hailing platforms, and major retail chains including Magnit and Fix Price.

Vladimir Region Governor Aleksandr Avdeev reported that drone strikes damaged local electrical substations, knocking out municipal power grids. Avdeev said utility crews restored heat and water supplies alongside roughly 80 percent of electrical service in affected areas of Vladimir by Sunday morning.
The Russian Defense Ministry claimed its air defenses intercepted 479 Ukrainian fixed-wing drones overnight across 16 Russian regions – including Vladimir, Belgorod, Bryansk, Kursk, and Rostov regions – alongside occupied Crimea and the Black Sea.
Consecutive strikes on Russian cloud architecture
The strike in Vladimir follows consecutive attacks against Yandex facilities earlier in the week, reflecting an expanding campaign targeting Russian digital networks and data-processing logistics.
On Thursday, Oct. 8, Ukrainian strike drones struck a Yandex data center in Sasovo, located in the Ryazan region, igniting a fire and forcing a full operational shutdown. That strike disabled server infrastructure used by Russian Railways (RZhD), mobile network operator MegaFon, and several national media outlets.
The following day, on Friday, Oct. 9, drones hit another Yandex facility in the regional capital of Kaluga, located southwest of Moscow. Yandex confirmed that multiple hardware modules were disabled in that attack.
Following the initial strikes, Yandex removed the locations of its data centers across four Russian regions from its digital mapping platform. The repeated disruptions contributed to a decline in Yandex shares of approximately 4 percent on the Moscow Exchange earlier in the week.
Ukrainian military analysts have noted that systematic interdiction of enterprise data centers and communications networks complicates Russian state logistics, disrupts corporate administration, and impairs digital command-and-control capabilities supporting the Russian war effort.
