Ukraine Needed Four Days to Gut Russia's Google

Pavel Belyavskiy drives for Yandex Taxi in Moscow. On October 11th he couldn't tell if fares were coming through at all, and he kept cancelling rides after waiting for passengers he could no longer reach. That is what a kinetic strike on a data center feels like from the sidewalk: not a headline, a cancelled ride.

Ukraine did not hack Yandex. It bombed the buildings Yandex runs on, and Russia's Google rolled over in four days.

Three Strikes, Three Supercomputers

On October 8th a drone attack hit Yandex's Sasovo facility in Ryazan Oblast, which housed two of three supercomputers used to develop the company's AI model. The next day, drones hit Kaluga, a 63-megawatt facility with over 3,800 racks. On October 11th, strike three: a 50-megawatt data center in Vladimir, designed for 2,880 racks, was completely shut down. That single site took out over 80 Yandex Cloud services: Compute Cloud, object storage, managed Kubernetes, PostgreSQL, YandexGPT API, Alice voice assistant, music, and smart home.

Cloudflare reports bot traffic from the Yandex network dropped to 0.4% of its maximum in the past two weeks. That is not degraded service. That is a company that stopped broadcasting.

Yandex's statement after the second strike: "Our teams are working day and night to do everything possible to keep services running and to help those affected by the incident."

Translation: the backup plan was another data center in the same country that is losing a war.

Redundancy Assumes You Have Somewhere to Fail Over To

Cloud companies survive outages by routing load to another region, provider, or continent. Yandex's regions are all inside Russia. When the enemy can put a drone through the roof of a specific facility, geographic concentration becomes a target list.

Ukrainian arms maker Firepoint said Kyiv used FP-1 one-way attack drones against Yandex's biggest data centre, and didn't need to guess where to aim. Yandex told the world exactly where its capacity lived.

President Zelensky framed this as retaliation, not improvisation: "We always respond in mirror-like fashion. You all know, they have been hitting and continue to hit our data centres. We are responding." Russia escalated into the compute layer first. Ukraine answered by hitting the one company whose outage simultaneously degrades Kremlin-aligned search results, disinformation bot networks, and the taxi and banking apps ordinary Russians use every day.

Yandex shares dropped more than 3.4% during Thursday trading on the Moscow Exchange after the first strike. Markets understood what the PR statements wouldn't say out loud.

Disinformation bots don't need Yandex's servers to exist; they can run on X, Quora, or Reddit through a Western VPN. That is a real escape hatch. It does not change the fact that Yandex's domestic infrastructure, the thing that makes it Russia's Google rather than just another website, got mapped and hit three times in four days.

What to watch: whether Yandex rebuilds inside Russia (same geography, same vulnerability) or tries to diversify abroad (politically radioactive for a company this close to the Kremlin). Watch supercomputer recovery specifically; losing Lyapunov and Chervonenkis delays YandexGPT training by however long it takes to replace NVIDIA-class compute under sanctions. And watch whether this becomes the template: both sides now treat data center addresses as legitimate military targets, not firewalls to breach but buildings to burn.
