Russian Strikes Target Ukrainian Data Centers as Kyiv Hits Yandex Facilities

Key points

• Russian forces struck the Tenet data center in Odessa on October 10, damaging cooling and power generation equipment.
• The Russian Ministry of Defense claimed the Tenet facility was used by Ukrainian armed forces to process and store information.
• Ukrainian operators report that Tenet’s total network capacity remains stable despite temporary local interruptions during repairs.
• Other Ukrainian facilities hit this month include a Ukrsibbank data center in Kyiv and the RX-Name facility in Mykolaiv.
• Ukrainian forces have struck three of Yandex’s five data centers in Russia over the last week, causing widespread internet outages.

Background

This latest escalation follows a pattern of infrastructure targeting observed in September 2026, where Russia intensified long-range attacks on Ukrainian telecommunications and data centers. At that time, Ukraine was negotiating with the US to license Patriot interceptor missile production to bolster air defense against such strikes. The current events represent a continuation of this strategic focus on digital infrastructure as a key battlefield.

How outlets are covering it

Data Center Dynamics emphasizes the physical damage to Ukrainian facilities, noting that Tenet’s cooling and power systems were significantly impacted, though the company maintains its overall network capacity is stable. The outlet highlights that Russian claims of military use for these civilian infrastructure sites are standard justifications for strikes. In contrast, the secondary source from Ukrainian Pravda focuses on a different aspect of the conflict, reporting on the Ukrainian Navy destroying two Russian boats and their crews. While Pravda does not detail the data center strikes, its coverage of naval engagements and other military actions provides context for the broader intensity of the conflict during this period. The two sources offer complementary views: one detailing the impact on digital infrastructure, the other highlighting kinetic military engagements at sea.

Why it matters

The targeting of data centers disrupts critical digital services for millions of users in both Ukraine and Russia. Damage to cooling and power systems can lead to prolonged outages and data loss, affecting businesses and government operations. The reciprocal strikes on Yandex facilities in Russia have already caused widespread internet outages and raised concerns about the resilience of Russian digital infrastructure. This pattern of infrastructure warfare highlights the growing importance of digital systems in modern conflict and the vulnerability of critical infrastructure to targeted attacks.

What to watch

Tenet has stated there is no fixed schedule for repairs, with temporary local interruptions expected in certain locations. The company has closed its office to visitors for part of the week due to ongoing technical work. Recovery from the strikes on Yandex facilities in Russia is expected to take months due to equipment shortages and legal restrictions on data storage. The situation may escalate further as both sides continue to target each other's digital infrastructure, potentially leading to more widespread disruptions in internet and telecommunications services.
