Ukraine Takes Out Yandex's AI Infrastructure in Drone Counterstrikes
Two of Yandex's five data centres are out of action after Ukrainian drone strikes hit facilities in the Sasovo and Kaluga regions on October 8th and 9th. Yandex, Russia's dominant search engine and the closest thing the country has to a homegrown Google, has been scrambling to keep its AI chatbot and various online services running since the attacks.
The strikes weren't random. They came directly after Russia launched its own drone campaign against Ukrainian data infrastructure, knocking out mobile and internet services for thousands of Ukrainians since late September. President Zelenskyy made no attempt to be subtle about the logic: "We continue to respond to Russia's attacks on Ukraine, and we're doing so with high precision. Another data center was hit as well — our symmetrical response."
Ukrainian firm Firepoint confirmed its FP-1 one-way attack drones were used in the Kaluga strike, which targeted Yandex's largest facility. The earlier Sasovo hit was arguably more significant from a technical standpoint: that site houses two of the three supercomputers Yandex uses to train its YandexGPT large language model. Knocking those out isn't just an infrastructure headache, it directly disrupts Russia's domestic AI development capacity.
Yandex said no staff were injured but admitted to service disruptions. Russian users reported problems with a fairly broad spread of platforms: the Ivi video streaming service, T-Bank's digital banking app, Russian Railways, a dating app, a real estate aggregator, and even the website of a top-flight football club. Not exactly a surgical list, but that's the nature of shared data centre infrastructure.
Data centres as military targets have become an uncomfortable pattern. Earlier in 2026, following US and Israeli strikes on Iran, Iranian drones took out several Amazon facilities in Bahrain and the UAE. The trend is clear: digital infrastructure is no longer a civilian abstraction kept separate from conflict.
Russia has been hitting Ukrainian cities, power grids, and residential buildings since the full-scale invasion began in February 2022. Ukraine, facing a persistent shortage of interceptor weapons, has leaned increasingly into its own long-range drone programme. Targets have included Russian military logistics, oil refineries, Black Sea shipping, and over the summer of 2026, warehouses belonging to Russian e-commerce giants Wildberries and Ozon.
The situation in the Black Sea is also deteriorating. Coordinated drone attacks sank two commercial ships on October 5th and 6th inside the exclusive economic zones of NATO members Romania and Bulgaria. Zelenskyy blamed Russia. Whether that's the start of something broader, or another grim data point in an already grinding conflict, is harder to say.
