TL;DR: Ukraine disabled five major Russian data centers in October 2026, knocking out Yandex, Sberbank and VKontakte facilities and setting back Russia's AI work, according to The Associated Press.

Ukraine's October drone campaign against Russian computing infrastructure has inflicted physical damage that analysts say will require months or longer to fix and has interrupted daily digital life across Russia.

According to The Associated Press, Kyiv struck three principal facilities operated by technology firm Yandex, plus a computing site linked to lender Sberbank and a site supporting social network VKontakte. The targets sit at the center of national cloud capacity, online commerce, financial processing and machine-learning development. The reporting describes Russia as proud of its progress in electronic commerce and its ambitions in artificial intelligence, ambitions now under strain after the loss of key sites in a full-scale invasion now in its fourth and a half year.

Al Jazeera, citing AFP and Reuters, separately reported that Ukrainian drones partly disabled Yandex AI computing capacity, with one hub partly placed out of service and another large hub shut down. That independent account confirms the core sequence: back-to-back hits on Yandex locations and a widening of Ukrainian operations toward technology infrastructure after Russian hits on computing hubs inside Ukraine.

When and where the five strikes landed

The series began Oct. 8, when Ukrainian aircraft hit the Yandex location at Sasovo in the Ryazan region, according to The Associated Press. That location contains two of the firm's three supercomputers used for AI model work. A second Yandex location in Kaluga was hit Oct. 9, and a third Yandex location in Vladimir was hit Oct. 11.

The campaign then extended beyond Yandex. The Associated Press reported that an AI and computing hub for Sberbank at Balakovo in the Saratov region was hit Oct. 14. Four days afterward, on Oct. 18, Kyiv struck a St. Petersburg facility serving VKontakte.

Al Jazeera placed the first two Yandex incidents in the same order, noting the Kaluga region site southwest of Moscow was hit after the Sasovo site in Ryazan. The outlet said Yandex acknowledged that the incidents struck at the heart of its operations and that staff were attempting to sustain services.

Yandex told the public that crews were laboring around the clock to keep products online and to assist people affected by the incident, describing the assignment as difficult, according to Al Jazeera. The Associated Press noted that Yandex, Sberbank and VKontakte have offered little detail about the extent of destruction.

What Russians lost access to

The practical effects have been broad. According to The Associated Press, users and firms across Russia described extensive interruptions to cloud platforms. Banking operations, electronic retail, location functions and taxi-hailing were affected. Alisa, Yandex's voice assistant, and multimodal conversational AI systems also experienced prolonged trouble.

The disruption reached beyond consumer apps. The Associated Press reported that effects extended to the court system, where arbitration tribunals were said to have called off or deferred hearings and lost entry to databases.

Yandex holds a central place in Russian online activity and in several former Soviet states, according to The Associated Press. Its portfolio spans search, cloud storage, payment tools, mapping and taxi-hailing, along with retail marketplaces. Nick Reiners, senior geotechnology analyst at Eurasia Group, told The Associated Press that Yandex combines functions associated in the United States with several different large platforms, with resources concentrated in a small number of computing sites. He called the concentration attractive from a targeting standpoint.

The Associated Press reported that the Yandex attacks produced unusually extensive interference, freezing payments, internet orders, cab bookings and retrieval of personal records. Al Jazeera noted that the company operates many programs that numerous Russians view as indispensable, alongside social networks.

Why AI development faces a long delay

Analysts interviewed by The Associated Press warned that restoration could consume months, if not years, and that Moscow's goal of leadership in AI could be pushed back substantially.

Mikhail Klimarev, head of the Internet Protection Society activist group, told The Associated Press: “This effectively sets Russia far behind in the AI race.”

The concern centers on high-performance hardware. The Sasovo site alone housed two of Yandex's three supercomputers, making its damage particularly consequential for training advanced models, according to The Associated Press.

Replacing specialized components is complicated by isolation. While detailed chip-supply reporting was outlined in a Council on Foreign Relations analysis republished by other outlets, The Associated Press emphasized the structural problem: Russia mandates domestic retention of data under a strict digital sovereignty rule, leaving few external backups. By contrast, Ukraine placed vital information on machines in allied European states, reducing harm from incoming Russian strikes.

Reiners told The Associated Press: “Because all the infrastructure and all the data is located inside Russia, it’s relatively easier to take down.”

Klimarev predicted that the episode could push leading Russian firms to transfer holdings outside the country and could prompt officials to relax moves toward tighter network control in order to limit harm, according to The Associated Press. He said: “Paradoxically, the strikes on data centers have saved the Russian internet from isolation, as they will now have to move computing assets, most likely, to Europe.” He added that many domestic enterprises were likely seeking rental computing capacity on the European market.

Why three fortified sites fell in four days

Computing sites present a large and delicate footprint. According to The Associated Press, petroleum plants and storage depots are vulnerable, but information hubs are even more exposed because dense rows of machines depend on steady electricity and temperature management. The outlet reported that a drone with a comparatively small explosive payload can cause enduring harm.

Yandex had rehearsed for a mishap that would disable a single location out of its six-site network, but the loss of three important locations in four days left it without preparation, according to The Associated Press. It remained unclear why anti-aircraft protection around the locations did not stop the drones.

Reiners told The Associated Press: “The problem in Russia is that they’ve got to cover a big country with air defense and they don’t have enough.”

A recent Middle East precedent underlines the point. According to The Associated Press, Iranian drones struck two Amazon Web Services locations in the United Arab Emirates and one in Bahrain. AWS said last month that it could not bring back access to materials and information stored at two of those locations.

Ukrainian President Volodymyr Zelenskyy framed the operation as retaliation, according to Al Jazeera. He said: “We always respond in mirror-like fashion.” He added that Russia had been striking Ukrainian computing hubs and that Kyiv was answering, while declining to disclose specifics.

Retaliation cycle and the wider aerial war

Information facilities are the newest focus in reciprocal air operations against essential systems, according to The Associated Press. Russian missiles and drones have battered Ukraine's electricity network and other important locations in an effort to sap determination and opposition. Moscow intensified those operations ahead of winter, taking advantage of a shortfall in U.S.-provided Patriot interceptors after Washington depleted stocks during its conflict with Iran.

Kyiv answered with large drone waves against Russian petroleum refineries, producing a severe fuel shortage and carrying the conflict to millions of civilians, according to The Associated Press. U.S. President Donald Trump attributed elevated world petroleum prices to those strikes, prices that rose mainly because of the American conflict with Iran. Earlier in October, Trump arranged with Russian President Vladimir Putin to bring in diesel fuel, a move that startled Ukraine and its partners.

Ukraine also struck enormous distribution centers belonging to leading online sellers Wildberries and Ozon, according to The Associated Press. The data-center raids followed closely after Moscow's own recent raids on Ukrainian computing hubs, which interrupted web connectivity and television transmission. Al Jazeera reported that Russian attacks on Ukrainian computing and telecom sites over the prior month included objectives in central Kyiv and left about 100,000 households with temporary loss of internet in one episode.

Al Jazeera also reported that Ukraine's military said it hit three missile-production-related locations across Russia overnight, including a components plant in the Tver region and an intercontinental ballistic missile dismantling center in the Nizhny Novgorod region intended to curb explosives and propellant supply, plus a strike on the Ukhta refinery of state firm Lukoil about 1,900 kilometers from the Ukrainian border. Those battlefield claims illustrate how the computing-site strikes fit within a wider Ukrainian effort against supply and industrial nodes.

For consumers and applied science, the lesson is concrete. Cloud dependence concentrates everyday transactions and cutting-edge research in a handful of structures that need power, cooling and specialized silicon. When those structures burn, checkout screens, maps, taxis and research clusters fail together, and rebuilding takes far longer than the drone flight that caused it.
