The War Over Data Centers: Ukraine and Russia Strike Each Other's AI Facilities Three Times in One Week; Zelensky Declares "Mirror Retaliation"

According to Al Jazeera, a data center of Russian technology and artificial intelligence company Yandex in the city of Vladimir was shut down after a drone strike on the 11th. In a service notice posted on Telegram, the company said the center "completely ceased" operations, advised users to activate their disaster recovery plans, and warned that "the allocation of remaining resources is considered unstable."

The strike caused no casualties, but some Yandex services were temporarily unavailable to users, emergency services were handling the situation on site, and the company is assessing the damage to its systems. The company, known externally as "Russia's Google," is deeply involved in Russia's AI development.

Sasovo—Kaluga Oblast—Vladimir: Three Strikes in Seven Days

According to Al Jazeera's review, Yandex facilities have been hit in succession over the past week: on October 9, the Sasovo data center was struck — the facility housed two of the three supercomputers Yandex uses for AI model development; the following day, a data center in Kaluga Oblast was hit by a Ukrainian drone and partially paralyzed; on the 11th, Vladimir became the third target. The three locations are situated to the southeast, southwest, and east of Moscow respectively, showing a strike pattern advancing along the European hinterland of Russia.

The Public Declaration of "Mirror-Style" Retaliation

Ukrainian President Zelensky publicly justified the strike after the Sasovo attack, saying in a speech: "We always respond in a mirror fashion. As you all know, they have been striking and continue to strike our data centers. We are responding. I cannot disclose all the details." According to Al Jazeera, Zelensky explicitly linked strikes against Russian data centers to previous Russian strikes and openly acknowledged this as reciprocal retaliation.

And reciprocity indeed runs in both directions. According to Al Jazeera's review, Russia has struck multiple Ukrainian data centers and telecommunications infrastructure repeatedly over the past month, including targets in central Kyiv, with the intent described as disrupting connectivity and digital commerce.

When Supercomputers Become Targets

Dragging data centers — civilian and dual-use infrastructure hosting cloud services, digital commerce, and AI training — into the target list means that the traditional boundary between "civilian" and "military" is thinning over such facilities. The two AI supercomputers at Yandex's Sasovo center were struck, and the Vladimir center was described as "completely ceased," with the company directly advising users to enter disaster recovery mode — these are not casualties in the trenches, but they strip the neutral shell off digital infrastructure under attack and make ordinary users' connectivity a visible bill of the conflict.

And the chain of retaliation defined by "mirror" logic means that every new strike simultaneously generates the legitimacy for the next strike.
