Ukrainian drone strikes hit three of Yandex's five Russian datacenters between October 7–9, causing serious damage and taking services including Yandex Cloud and Yandex Pay offline. Engineers are working to restore services, with connectivity reportedly at just 30% of normal levels, though the company assures users their money is safe. The attacks were described by Ukrainian President Zelensky as retaliation for Russian drone strikes on Kyiv datacenters, amid broader ongoing exchanges targeting each other's infrastructure.
