Ukrainian strikes on Yandex data centers did not halt Russian disinformation, experts say

Ukrainian drone attacks hit Yandex data centers in three Russian regions between Oct. 9 and 11, leading to online claims that Russian bot activity had collapsed. Experts found no evidence that the strikes disrupted Moscow-backed disinformation or influence operations. A widely shared chart actually tracked automated requests from Yandex's own web crawlers, not social media bots or trolls.
Ukrainian drone attacks between Oct. 9 and 11 targeted Yandex facilities in three Russian regions, a move framed as retaliation for comparable Russian strikes in Ukraine. Yandex confirmed damage forced its Vladimir Oblast site offline and said some domestic online services were affected.
Online speculation about collapsing Russian bot activity centered on a Cloudflare graph. That graph tracked automated requests from Yandex's own network, chiefly search indexing crawlers, not social media trolls. Polish monitors found no meaningful decline in disinformation accounts from Sept. 30 to Oct. 11.
The episode may shape public perceptions by making unverified claims about sudden shifts in online influence seem credible. Social media users, journalists, and policymakers could be affected if they rely on misleading charts or official statements without published data. It may also complicate efforts to assess disinformation, as real service disruptions and unrelated fluctuations are conflated. Continued monitoring by researchers and fact-checkers could help distinguish platform outages from changes in coordinated influence activity.
