According to Al Jazeera, Ukrainian drone attacks have partially crippled Russian digital giant Yandex's AI data center in the Kaluga region. The attack occurred on Friday, a day after another major Yandex data center in the Ryazan region, which housed two of the company's three supercomputers used for developing AI models, was also attacked and shut down. These attacks indicate that Ukraine's military operations are expanding their target scope to include Russia's technological infrastructure. Additionally, the Ukrainian military also attacked three missile production facilities within Russia overnight and launched an assault on Lukoil's refinery in Ukhta.
