Ukraine’s Drone Strikes Disable Yandex Data Centers
By Drooid · · How we work
Background & Context
Since Russia’s full-scale invasion in February 2022, Ukraine and Russia have been locked in a long-range aerial war while ground forces remain largely static. In recent weeks Kyiv has intensified attacks on Russian infrastructure deep inside the country, targeting facilities that Moscow relies on for its war effort. The campaign now includes strikes on the data-center network of Yandex, Russia’s leading internet and artificial-intelligence company.
Scope of Disruption
In early October 2026 Ukrainian drones hit three Yandex data-center sites within four days. The latest strike—reported by ASTRA and the Kyiv Post—shut down the 40-to-50 MW facility in Vladimir, a hub that hosts up to 2,880 server racks and powers dozens of consumer services. Outages affected Yandex’s Alice voice assistant, Yandex Music, Telemost videoconferencing, Yandex Smart Home, and cloud components such as Compute Cloud, Object Storage, Managed Kubernetes, PostgreSQL and ClickHouse. Users in Russia, Kazakhstan, Belarus and Armenia reported failures in ride-hailing, banking and retail platforms.
Earlier attacks on Yandex’s data centre in the Ryazan region (Sasovo) and the Kaluga region forced partial or complete shutdowns. The Ryazan site houses two of Yandex’s three supercomputers used for AI development; the Kaluga centre covers roughly 130,000 sqm and consumes electricity comparable to 220,000 UK households. Yandex confirmed no injuries but said restoration timelines remain uncertain.
Official Statements & Responses
President Volodymyr Zelenskyy posted on X that Ukraine would halt strikes on Russian oil refineries if Moscow ceased attacks on Ukraine’s energy grid.
> “Ukraine will be ready to stop striking Russian oil refineries if Russia stops striking our energy infrastructure.” — Volodymyr Zelenskyy, Ukrainian president
Foreign Minister Andrii Sybiha defended Zelenskyy, stating the president has popular support.
> “He has the support of the Ukrainian people, and they have the right to decide.” — Andrii Sybiha, Ukrainian foreign minister
U.S. President Donald Trump suggested Ukraine should replace its leader, arguing Zelenskyy has failed to secure deals.
> “I suggest they get a new leader who can make a deal because he could have made many deals and for some reason he never does.” — Donald Trump, president
Russian officials reported air defenses intercepted 479 Ukrainian drones across 16 regions, including Vladimir, Belgorod, Bryansk, Kursk and Rostov. Regional governor Aleksandr Avdeev said municipal heat, water and roughly 80 % of electricity were restored after the Vladimir attack.
Conflicting Reports & Gaps
The precise extent of service disruption remains unclear. Yandex’s Telegram updates confirmed power interruptions in the “ru-central1-a” availability zone but did not quantify the impact on end-user applications. Independent monitors reported outages in banking, ride-hailing and retail services, yet public outage monitors did not observe a uniform failure across Yandex’s consumer platforms. The Kyiv Independent could not verify images of a fire near the Vladimir facility, and Yandex has not publicly linked the incident to a drone attack. Ukrainian officials claim the strikes are retaliatory; Russian authorities label the Yandex sites as “critical infrastructure” used by Ukrainian military intelligence, a claim not independently substantiated.
Impact and Implications
The coordinated attacks on Yandex’s data-center network illustrate Kyiv’s strategy of targeting revenue-generating Russian assets to pressure Moscow’s war-fighting capacity. Disruption of cloud-computing and AI resources could force Russia to divert technical personnel and repair resources away from military projects. The strikes also risk escalating the aerial conflict and may invite further Russian retaliation against Ukrainian civilian infrastructure.
