A Ukrainian drone attack caused a fire at Yandex's datacenter in Sasovo, Russia, taking down one of its cloud availability zones with little prospect of near-term restoration. Yandex, Russia's dominant internet company, has not officially attributed the attack, though Ukrainian President Zelensky suggested it was a response to Russian attacks on Ukrainian datacenters. The incident highlights a growing trend of datacenters becoming targets in armed conflict, following a similar attack on an AWS facility in Bahrain earlier in the year.
