# Ukrainian drones hit three Yandex data centers in four days By Aurelia Crown (The Golden Hour), GEN, the Golden Era Network Published: 2026-10-12T15:33:36.051Z Section: Money & Policy Event date: October 12, 2026 Tags: Yandex, Ukraine, data centers, Russia, cloud, supercomputers URL: https://goldenera.si/news/yandex-data-centers-drone-strikes/ > Ukrainian drone strikes shut two Yandex data centers and damaged a third in four days, disrupting taxis, payments, email and cloud services across Russia. ![A taxi driver and a delivery courier on a dusk city street look worriedly at their phones.](https://goldenera.si/media/articles/yandex-data-centers-drone-strikes/hero-og.jpg) Ukrainian drones hit three of Yandex's six data centers in Russia between October 8 and 11, according to The Record, forcing two facilities to shut down completely and damaging infrastructure at the third. In Russia, disruptions affected ride-hailing, payments, email and connected home devices, The Record reported. RFE/RL reported interruptions to Yandex Go and related taxi and banking services in Armenia, Belarus, Kazakhstan, Kyrgyzstan, Uzbekistan and Serbia. For a company that handles around 70% of Russia's search queries, according to bne IntelliNews, this is a staggering week. Yandex also runs the generative model YandexGPT, plus taxi, delivery and cloud services used by businesses nationwide. ## Three strikes, three regions The first hit came overnight October 7-8 in Sasovo, in the Ryazan region, where a fire forced Yandex to shut the facility. Ukrainska Pravda places it at the Sasta plant, which it calls important to Russia's defense industry, and reports that the site houses two of Yandex's three supercomputers used to train AI models. On October 9, drones partly disabled the large data center in the Kaluga region southwest of Moscow, according to bne IntelliNews, taking several modules offline. Governor Vladislav Shapsha said 26 drones were shot down over the region but others hit, injuring nine people. Yandex said no employees were hurt. The third strike landed October 11 in Vladimir, about 180 kilometers east of Moscow. "The data center has shut down completely, and the remaining infrastructure is unstable. The platform is operating in emergency mode," Yandex said in a statement. Vladimir is home to Galushkin, a supercomputer The Record describes as among the most powerful in Russia. The three targeted sites have a combined electrical capacity of roughly 115 megawatts, according to The Record. ## What stopped working The Russian internet watchdog reported trouble with email, taxi booking, food ordering and payments through Yandex Pay. The Alice voice assistant and connected smart home devices reportedly went quiet in some households. The details are very human. Yandex Pay users complained they could not transfer or withdraw money, and taxi drivers and couriers could not withdraw their earnings, according to Ukrainska Pravda. Some concert-goers chasing Intickets refunds never got their confirmation codes in Yandex Mail. Yandex Cloud reported power interruptions in its ru-central1-a availability zone. More than a dozen third-party services hosted on Yandex infrastructure were also disrupted, according to The Record, including retailers, internet providers, an online psychotherapy service, fitness businesses and the Russian segment of TikTok. Yandex Cloud had about 64,000 customers as of mid-2026, per the company's financial disclosures, and Yandex has not said how many were affected. Yandex Go service resumed in Kazakhstan on October 12, though the company says it is still working to stabilize performance. ## The money question Here is where it gets expensive. On October 10, Yandex updated its user agreement to list drone and missile attacks as force majeure that could exempt it from contractual obligations, according to The Kyiv Independent. Read that as a company preparing for more of this. Russian state media reported that Yandex struck deals with rival clouds Selectel, K2Cloud and VK Cloud to help customers move their data faster. Rivals as lifeboats: a very expensive kind of friendship. The cited reporting provides no total monetary damage estimate. What is reported is the timeline. The Insider says Yandex needs at least six months to replace the damaged equipment and must source components abroad. IT market participants told Kommersant that getting significant volumes of server hardware before the end of 2026 is virtually impossible. The Insider also found certain Yandex Cloud services had already risen more than 16.6% after two tariff hikes in 2025-2026. Customers who were paying more are now getting less, and that is the kind of math boardrooms remember. ## What to watch Start with the supercomputers. Yandex has not disclosed whether any were damaged, and that is the question that matters most for its AI ambitions. Then watch the policy response. Digital Development Minister Maksut Shadayev said his ministry is working with the Defense Ministry on security at Yandex facilities. "Yandex has faced an unprecedented attack. We are discussing how to protect these facilities," he said. On motive, President Volodymyr Zelensky told reporters: "We always respond in kind. You all know that they have attacked and continue to attack our data centers. We responded." The Record notes that Russian strikes in late September damaged at least six Ukrainian data centers and telecom infrastructure of Kyivstar and Ukrtelecom, and a September 23 strike disrupted fixed-line internet for roughly 100,000 households around Kyiv, according to Ukrainian officials. One outlet, bne IntelliNews, wrote that Kyiv has not claimed the attacks, though Zelensky's remarks are reported by The Record, RFE/RL and The Kyiv Independent. Zelensky also said at the Warsaw Security Forum on October 12 that the strikes meant fewer pro-Kremlin bots online. Researchers quoted by RFE/RL dispute the evidence: the Cloudflare Radar drop in automated traffic from Yandex's network, to roughly 0.4% of its recent peak, mostly reflects Yandex's own search crawlers, they say. Still unanswered: how long emergency mode lasts, and when every availability zone is back at capacity. Data centers are now targets on both sides of this war, and the cloud bills will follow. *GEN's AI newsroom wrote this story from the sources below, and an AI standards desk checked every claim against them before it went live.
