Ukraine strikes Yandex data centre in third attack on Russian tech giant

A Ukrainian drone strike damaged Yandex’s data centre near Vladimir, east of Moscow. Yandex said operations there were completely suspended, although no one was injured. The incident mattered because the facility supported services used by many people, and some became unavailable.

Yandex confirmed the damage on Telegram. It said the centre’s connectivity was being restored. The Vladimir strike was the third attack on Yandex sites in one week. Earlier, facilities in Sasovo and Kaluga were also hit. Those attacks caused problems for services including Yandex’s AI chatbot and smart home devices.

The disruption showed how physical damage can affect online life. Yandex said its data centres were critical to normal service. The company warned that it was difficult to predict when all services would return. The attacks also formed part of wider strikes on infrastructure during the continuing war between Russia and Ukraine.

A data centre is a secure facility where powerful computers, storage systems, and network equipment process and deliver digital services. It stores information and handles requests from users. Search tools, taxi apps, food-ordering platforms, smart home devices, and AI chatbots all depend on such computing infrastructure.

For example, when someone requests a taxi or asks an AI chatbot a question, computers in a data centre help process the request and send back a response. Yandex runs several services from its data centres. The company said these facilities were critical for the normal operation of its services, including its taxi and food-ordering apps used by tens of millions of people.

The Vladimir damage showed why these buildings matter. Some Yandex services became unavailable after attacks on its facilities. A wider outage can affect many users at once because one centre may handle shared data, connections, or computing work for several services. Yandex worked to restore connectivity after the strike.

Yandex’s sites were hit three times in one week. The company operates five data centres in total. That means the attacks affected three of its five facilities, leaving two others outside the incidents described in the article.

The first two strikes mentioned by Yandex hit facilities in Sasovo on Thursday and Kaluga on Friday. The third strike damaged the centre in Vladimir on Sunday. Yandex said the first attacks caused problems for some services, including its AI chatbot and smart home devices. The Vladimir centre then suspended operations completely.

This scale matters because losing three sites from a five-centre system can place heavy pressure on the remaining facilities. Yandex said its data centres were critical to normal service and that it was difficult to predict when services would return. The article does not state whether the other two centres handled all displaced activity or how much capacity remained available.

The attacks caused some Yandex services to become unavailable or unreliable. The company specifically reported problems with its AI chatbot and smart home devices. It also warned that some services were unavailable after the Vladimir centre was damaged. Yandex operates taxi and food-ordering apps used by tens of millions of people.

A data centre can support several digital services at once. It may provide the computing power, stored information, and network connections needed to handle user requests. If equipment or connectivity is damaged, those requests may fail or be delayed. The effect can spread across services that share the same facility or depend on links to it.

Yandex said its data centres were critical for normal operations and that restoring service was difficult to predict. The company worked to restore connectivity after the Vladimir strike. The attacks demonstrated that damage to one physical site can create disruptions far beyond the building itself, potentially affecting large numbers of users.

Ukraine said it was targeting places that provide revenue streams for Moscow’s war machine. Yandex was described as a Russian technology giant, known as “Russia’s Google.” The stated aim was not only to disrupt a company, but also to pressure Russia’s ability to generate or use resources during the war.

The attacks could affect Russia’s war effort in two ways. First, damage could interrupt important technology services, including systems used by millions of people. Second, Kyiv said repairs could force Russia to divert resources to fix the damage at Yandex. That would create another demand on money, equipment, and personnel.

The article does not quantify Yandex’s revenue or the resources diverted after the strikes. It does show that the attacks formed part of wider Ukrainian strikes on infrastructure. Russia and Ukraine have increased such attacks as the war continues, while Yandex works to restore connectivity and return affected services online.

Infrastructure has become a target because it supports economic activity, public services, and the wider war effort. The article says Russia and Ukraine have stepped up attacks on infrastructure in recent months. It identifies technology facilities and oil refineries among the sites involved, but does not give a complete explanation for every attack.

Ukraine said it targeted places that provide revenue streams for Moscow’s war machine. It argued that damage at Yandex could make Russia divert resources to repairs. Separately, US President Donald Trump urged Ukraine to stop attacking Russian oil refineries so Moscow could release more diesel to global markets. That proposal drew criticism in Europe and sparked a diplomatic row with Volodymyr Zelensky.

The continuing attacks can disrupt services, damage economic capacity, and create repair demands. Russian strikes have also hit Ukrainian data centres, causing internet outages and prompting some companies to move servers abroad. The article gives no timetable for an end to the infrastructure campaign as the war enters its fifth year after Russia’s full-scale invasion.

Data centres can keep services running by using backup equipment, duplicate data, several locations, and network connections between them. If one site is damaged, systems may shift some work to another site. This approach reduces dependence on a single building, although it cannot guarantee uninterrupted service.

Yandex operates five data centres, giving it multiple locations to support its services. However, the article says two centres were hit before the Vladimir strike, and some services became unavailable. Yandex then worked to restore connectivity at Vladimir. The example shows that backups and alternate sites help, but losing several facilities can overwhelm remaining capacity or interrupt links between systems.

The current reality is that digital services still depend on physical infrastructure. Russian strikes previously caused internet outages in Ukraine and led some firms to move servers abroad. Yandex’s attacks may encourage stronger redundancy, wider geographic distribution, and more backup planning. The article does not state which specific backup systems Yandex uses or whether all services were rerouted.
