Russian bot traffic has dropped dramatically in the past few days after Ukraine knocked out Yandex’s biggest data centers, with a third attack happening last night. Cloudflare reports that bot traffic from the Yandex network has dropped to just 0.4% of the maximum number of HTTP requests recorded in the past two weeks. It initially dropped to around 57% on Oct. 8, which happened when Ukraine hit a Yandex data center housing two supercomputers in Sasovo, Russia, located around 195 miles to the southeast of the Kremlin. A second, bigger Yandex campus in Kaluga, about 220 miles to the west of Sasovo, was knocked offline yesterday.
These attacks are apparently Ukraine’s response to Moscow’s strikes on its own data centers, some of which resulted in the outage of some of the most popular piracy websites.

⚠️ Confirmed: Metrics show a second collapse in the networks of Russian tech giant Yandex after a new Ukrainian drone attack on data centers in Vladimir this morning. The campaign comes not long after Russia's threat to give Ukraine a "digital detox." pic.twitter.com/jOVL5BjYNR

Three consecutive Ukrainian drone attacks on data centres operated by Russian technology company Yandex have caused disruptions to more than 80 of its digital platforms and third-party but related services, such as banking apps and ride-hailing services. Bot traffic from the Yandex network has also fallen to almost zero.
