Yandex Shuts Down Third Data Centre in Four Days After Ukrainian Drone Strike Hits Vladimir Facility

Ukraine’s widening campaign against Russian digital infrastructure claimed its third major target in four days on Sunday, when a drone attack damaged a Yandex data centre in the Vladimir region east of Moscow and forced the company to shut the facility down completely.

The Russian technology and AI company said on Sunday that the strike had damaged the site’s infrastructure and that operations at the data centre had been completely halted. No one was injured in the attack, it said, but some of Yandex’s services are currently unavailable to users, according to Reuters.

The Vladimir shutdown caps a sequence of three strikes in as many days against the company often described as “Russia’s Google”, which is heavily involved in Russia’s artificial intelligence development. On Friday, Yandex said its data centre in the Kaluga region southwest of Moscow had been struck by Ukrainian drones and partly put out of action. A day earlier, a Ukrainian attack shut down Yandex’s data hub in Sasovo, southeast of Moscow, where two of the three supercomputers used to develop the company’s AI models are housed, Reuters reported.

According to the Associated Press, the Sunday attack on the Vladimir facility caused outages across Yandex’s services, with the Russian independent news outlet Astra reporting that users in dozens of Russian cities, as well as in Kazakhstan, Belarus and Armenia, were unable to order taxis or access banking services.

The successive strikes mark a sharp expansion of Ukraine’s targeting inside Russia, moving from the energy and refinery facilities that have dominated its deep-strike campaign to the computing infrastructure that powers one of the country’s most important technology companies. Reuters noted that the Friday Kaluga strike widened the scope of Ukraine’s attacks inside Russia after Moscow hit data hubs in Ukraine.

A three-day sequence against ‘Russia’s Google’

The first strike came in the early hours of Thursday. Yandex said in a statement that its Sasovo data centre had been seriously damaged in a drone attack and completely shut down, the Forbes Europe site reported, citing the company’s October 9 statement. The Sasovo site is of particular significance: two of the three supercomputers Yandex uses to develop its AI models are housed there, and Yandex has not confirmed whether those machines were damaged or could be restored, according to Reuters.

Friday brought the second strike. “This morning, another of our data centres, in Kaluga, was attacked. Part of its infrastructure is out of service,” Yandex said, according to Forbes Europe. The company identified the attacker as Ukrainian drones. Ukrainian arms maker Firepoint, for its part, said Kyiv had used its FP-1 one-way attack drones to mount the strike against what it described as Yandex’s largest data centre, and claimed several of its modules had been completely knocked out of action, according to TBS News.

The scale of the Kaluga facility underlines the ambition of the attack. Fire Point put its design capacity at 63 megawatts, according to reporting by the Institute for the Study of War cited by Forbes Europe. The regional governor of Kaluga said nine people were injured in the regional drone attack, Forbes Europe reported.

Then came Sunday. In a statement carried by the Yandex Cloud Telegram channel, which provides operational updates on service availability, the company said: “As a result of the drone attack, the infrastructure of Yandex’s data centre in Vladimir was damaged. Operations at the data centre have been completely halted. There were no injuries,” according to the Associated Press.

Services under strain, shares slide

The commercial fallout was visible within days. Yandex provides a wide range of digital services used by millions of Russians daily — navigation, music, films and food orders — alongside cloud computing services on which many businesses depend, according to Reuters.

Alexander Savitsky, who runs a start-up dating app called Pulse with 8,000 users, told Reuters that none of the app’s users had been able to access the platform since Thursday, and that the company was unable to reach its backup database in Yandex Cloud, receiving an “internal error” message when trying to restore it elsewhere. “We have no confirmation of actual data loss, but the situation is serious: the project represents three years of work,” Savitsky said, according to TBS News. “The main risk is losing users and their trust: people can’t use the app, and there’s no telling how many will return once service is restored.”

Yandex said it was facing a difficult challenge to maintain its services and had struck a deal with other cloud providers to enable clients to swiftly move their data and services, Reuters reported. The company’s shares fell by more than 4 per cent on the Moscow exchange. Maryana Lazaricheva, head of equity research at T-Investments, warned that the strikes could affect Yandex’s revenue and pose risks to its business customers, according to AnewZ.

Analysis: Why It Matters

The three-day sequence against Yandex is best read as the opening of a new front in Ukraine’s deep-strike campaign, and one of its most symbolically loaded. For more than two years, Kyiv’s long-range drones have concentrated on refineries, depots and oil terminals — targets chosen to choke the fuel that feeds Russia’s war economy and to squeeze the revenues that fund it. Data centres represent a different logic: not war finance, but war-adjacent technological capacity, and civilian digital life at the same time.

The choice of Yandex is no accident. The company is not a military contractor; it is the backbone of everyday Russian internet life — the dominant search engine, the largest taxi-hailing network, a major music and video platform, and one of the country’s biggest cloud providers. It is also, crucially, at the centre of Russia’s AI ambitions. Strikes that take two of the three supercomputers used to train Yandex’s AI models out of action — even if only temporarily — touch the hardware layer of Russian artificial intelligence at a moment when Moscow is pushing AI development as a strategic priority. The retaliation framing is equally clear: Reuters reported that the campaign widened after Moscow hit data hubs in Ukraine, making this a reciprocal exchange over civilian computing infrastructure rather than a one-sided initiative.

The operational pattern also tells a story about Ukrainian drone warfare in 2026. Three facilities in three days — Sasovo, Kaluga, Vladimir — all within a few hundred kilometres of Moscow, each identified, struck and at least partly disabled in rapid succession. That suggests a deliberate sequence, not opportunistic attacks: Ukrainian planners appear to have mapped Yandex’s infrastructure and worked through it methodically. The use of the FP-1 one-way attack drones, publicly claimed by their manufacturer Firepoint, adds a domestic-defence-industry dimension: Ukraine is now striking Russia’s technology champion with weapons built by its own technology sector.

There is a civilian-harm question the strikes raise, and it should be stated plainly. A refinery strike raises fuel prices and cuts military supply; a data-centre strike degrades the services ordinary people use to order taxis, listen to music and run businesses. The Astra-reported outages — taxi orders and banking services down across dozens of Russian cities and neighbouring countries — show how quickly a strike on cloud infrastructure propagates into daily life far from any front line. Whether Ukraine calculates that this civilian friction is an acceptable cost of degrading Russian AI capacity, or whether the goal is precisely that friction, remains undeclared. Neither Kyiv nor Moscow has laid out a doctrine for this new front.

The market and business reaction deserves attention too. A 4 per cent share-price fall is modest in wartime, but the episode exposed a concentration risk inside Russia’s digital economy: thousands of businesses, from small dating apps to large enterprises, discovered this week that their data and services lived inside infrastructure that could be shut down overnight. Yandex’s hurried deal with rival cloud providers to migrate clients is an admission of that vulnerability. Expect Russian regulators and large companies to spend the coming months on redundancy and geographic diversification of cloud hosting — a costly exercise that is itself a form of economic damage.

Finally, the timing lands in an already volatile moment in the war’s diplomacy. The Associated Press noted that the Vladimir strike came a day after US President Donald Trump said it was time for Ukraine to “get a new president”, blaming Volodymyr Zelenskyy for high diesel prices and suggesting he had not done enough to end the war. Kyiv’s decision to press ahead with a high-profile infrastructure campaign — while simultaneously pausing refinery strikes, as has been reported amid the Trump-Zelenskyy row over diesel prices — reads as a signal of its own: Ukraine can calibrate its deep strikes for American audiences while still demonstrating, to Moscow and to Washington alike, that its long-range capability is intact and expanding. The diesel deal with Russia and the data-centre strikes against Russia are, in that sense, two sides of the same Ukrainian strategy — leverage preserved in multiple registers.

What to Watch Next

1. Service restoration timelines. Yandex said its teams were working around the clock, but the company has not confirmed whether the Sasovo supercomputers were damaged or can be restored. The length of the outage is the first measure of how hard the campaign has hit.
2. Russian retaliation against Ukrainian digital infrastructure. The strikes were themselves presented as responses to Russian attacks on Ukrainian data hubs; Moscow’s next move will show whether a tit-for-tat over computing infrastructure is now the pattern.
3. A fourth facility. Ukraine has worked through three Yandex sites in four days. Whether the sequence continues — or pauses — will reveal whether this was a bounded operation or an open-ended campaign.
4. Regulatory and business fallout in Russia. Watch for state pressure on critical businesses to diversify cloud hosting, and for any compensation or insurance disputes from affected Yandex Cloud customers.
5. The civilian-outage question. If taxi and banking outages persist or spread, domestic Russian discussion of the strikes’ cost may grow — and Ukraine may have to reckon with how its strikes on civilian-facing infrastructure are perceived internationally.
