Oct 9 (Reuters) - Russian ‌technology and ​AI ​company Yandex said on Friday that several modules at its data centre in ‌Russia's Kaluga region had been completely disabled by ⁠a drone attack, the second in two days.

Some of ‌the company's services may ‌be disrupted, Yandex said, adding that no one was injured in the attack southwest of Moscow.

On ​Thursday, a Ukrainian drone hit another Yandex data centre in the Ryazan region, southeast of ⁠the capital, where two of the three supercomputers used to develop ​the company's AI model are housed. Yandex said it was assessing the damage from ​that strike and could not ‌confirm whether the equipment could be restored.

Both Russia and Ukraine have expanded ⁠drone attacks this year on economic targets, from energy facilities and refineries to ports and vessels carrying oil ⁠and grain, e-commerce warehouses and, most recently, data centres.

Russia has ​conducted a strike campaign against Ukrainian data centres and telecommunications infrastructure over the past month, including targets in central ‌Kyiv.

"We always respond in mirror-like fashion," Ukrainian President Volodymyr Zelenskiy said on ‌Thursday. "You all know, they have been hitting and ⁠continue to hit our ‌data centres. We ​are responding. I can't share all the details."
