Ukrainian Drones Hit Three Yandex Data Centers in Four Days as Zelensky Claims Russian Bot Activity Dropped Though Researchers Dispute Link

BLUFKyiv's strikes degraded Yandex search crawling but not Russian bot activity on social platforms, and further drone attacks on Yandex data centers are likely within the next two weeks.

Ukrainian drones struck Yandex data centers in Sasovo on October 8, Kaluga on October 9, and Vladimir overnight on October 11, and Yandex said it fully halted Sasovo and Vladimir 12. At the Warsaw Security Forum on October 12, Zelensky said social media had "become a little easier to breathe on" because fewer bots were active, and RFE/RL reported he called the strikes a response to Russian attacks on Ukrainian data centers 2. Cloudflare Radar showed automated requests from Yandex's network falling to 0.4% of their two-week peak, and Cybernews reported recovery began Sunday 23. The researcher behind @antibot4navalny told RFE/RL the chart measures website crawling, not social media accounts 2, and CAT-UA analyst Yevhen Luzan told Euromaidan Press his sampling shows no clear drop in bot activity 1.

Analysis
Ukrainian drones are likely to strike at least one more Yandex data center between October 13 and October 27, 2026. Confidence is high, based on three strikes in four days, Kyiv's stated tit-for-tat rationale, and Yandex's confirmation of each hit. Moscow's talk of air-defense cover may raise the cost of repeat strikes. The claim that the strikes cut social-media bots is unsupported, since the Cloudflare drop measures Yandex search crawling and Ukrainian monitoring shows no clear fall in bot posting. Sources agree on the strike facts and independently doubt the bot claim, though they share the same public chart data and researcher commentary. Strikes may still have degraded some influence infrastructure on Yandex Cloud, masked by small samples and proxy networks. Allied officials should not cite the claim as proof that strikes can disable influence operations before the November US midterms, and Russian planners may have to divert air defense to data centers.
