Did Russia attack Ukrainian IT infrastructure before Ukraine struck Yandex data centers?

Published

Verdict
True
Verification confidenceHigh

Explanation

Yes. Documented Russian attacks on Ukrainian data centers and telecommunications infrastructure preceded Ukraine's October 2026 strikes on Yandex facilities. The chronology supports this specific claim.

The Record reported on September 24 that Russian drone strikes had damaged Kyiv data and telecommunications facilities, citing affected providers. Yandex's own October 9 statement dates the attack on its Sasovo data center to the night of October 7–8 and reports a further attack in Kaluga on October 9.

Reuters independently reported that the Yandex strikes followed Russian attacks on Ukrainian data hubs. Ukraine described its actions as retaliation, but that stated motive is separate from the documented sequence. This check concerns physical attacks preceding the Yandex strikes, not which country initiated every form of cyber or infrastructure warfare.

Russian attacks on Ukrainian digital infrastructure were documented before the October 2026 Yandex strikes.
