Yandex Reports Drone Attacks Disabling Three Data Centres in Four Days (Sasovo Oct 8, Kaluga Oct 9, Vladimir Oct 11); Reuters Attributes the First Two to Ukrainian Drones

Sequence only, with date kinds. The task lead cited Reuters Oct 9 and Oct 11; Reuters.com was not fetchable, so both were read as Reuters text republished by The Star (named relay).

• 2026-10-08 (event date per Reuters, “Thursday”): a data centre in Ryazan region (Sasovo) hit; Reuters says a Ukrainian drone. It houses two of the three supercomputers used to develop Yandex’s AI model (Reuters Oct 9).
• 2026-10-09 (Yandex statement / Reuters publication): Kaluga region modules “completely disabled”; Yandex called it the second attack in two days; no injuries.
• 2026-10-09 (statement date): Zelensky said Thursday, “We are responding” (per Reuters; the quote does not name a target).
• 2026-10-11 (Yandex statement / Reuters publication): Vladimir region data centre fully shut down; Reuters calls it the third major data centre out of action in a few days.

Attribution caveat: Yandex did not name an attacker in the sources read. Reuters attributes Ryazan and Kaluga to Ukrainian drones; the Oct 11 dispatch does not name an attacker for Vladimir. Reuters also notes Russia has struck Ukrainian data centres.
