Russian tech giant Yandex, which operates the country's most widely used search engine, reported that a Ukrainian drone attack had disabled several modules at its data center in Kaluga, one day after a drone strike left its data center in Sasovo in the Ryazan region seriously damaged and fully offline, RBC reported on Oct. 9. Yandex said it had arranged with rival providers Selectel, K2 Cloud and VK Cloud to fast-track the migration of affected cloud clients.
