Ukraine Strikes Yandex Data Centers; Claims of Reduced Russian Bot Activity Lack Evidence

Between October 8 and 11, 2026, Ukraine conducted drone strikes against three of Russia's Yandex data centers in response to Russian attacks on Ukrainian internet infrastructure. Yandex, Russia's largest technology company often described as its equivalent to Google, acknowledged the attacks and reported service disruptions, including the shutdown of its Vladimir Oblast facility.

Following the strikes, claims spread widely on social media that Russian disinformation and bot activity had significantly decreased. Ukrainian President Volodymyr Zelensky stated on October 13 that it "suddenly became a little easier to breathe on many social platforms," with "less hate, less division, and fewer provocations." Similar assertions circulated from European officials, including Polish minister Tomasz Siemoniak, who claimed his country's security service had confirmed a "radical decline in Russian bot activity."

However, experts and fact-checkers across multiple organizations report no concrete evidence supporting these claims. The apparent source of confusion stems from Cloudflare data showing a sharp drop in bot activity from Yandex's network—declining to 54.7 percent after one strike and to 0.3 percent after the third. Cloudflare clarified that this data measures automated web requests to websites on its platform, primarily Yandex's own search engine crawlers that index web content, not social media bot activity or disinformation campaigns. Roman Osadchuk, director of Threat Intelligence at LetsData, stated that such a consolidation of bot and troll activity across multiple platforms "has nothing to do with activity by what is commonly referred to as Russian bots or trolls on social media."

Research groups tracking Russian influence operations reported no significant disruption. The US-based dTeam, which monitors Moscow-linked influence campaigns, found no traffic change from known Russian accounts and bot clusters. Accounts associated with known pro-Kremlin influence operations, including Storm-1516 and Matryoshka, remained active on social media after the strikes. Poland's state-run Disinformation Analysis Center recorded no significant decrease in Russian disinformation account activity between September 30 and October 11, with only isolated individual accounts becoming inactive. Claims linking the strikes to reduced activity by far-right German and US political movements were disputed by fact-checkers, with some noting the supporting graphs lacked sources or methodology. Zelensky's office later clarified that the president was "talking about the atmosphere on social media" based on user reports of fewer hateful comments, rather than data-confirmed reductions in bot activity.
