Ukraine drone strikes cripple Yandex; Russian bot traffic plummets 94%

Ukraine conducted three drone strikes on Yandex data centers between October 8 and 11, causing severe disruptions to Russia's largest internet technology company and triggering a dramatic decline in automated online traffic. Strikes targeted facilities in Sasovo (October 8), Kaluga (October 9), and Vladimir (October 11), with the Vladimir site experiencing complete operational suspension. Yandex reported at least 84 services offline, and network traffic fell to 30% for Yandex Cloud and 63% for Yandex LLC. According to Cloudflare Radar analysis, automated HTTP requests from Yandex's network fell approximately 94% by October 11, dropping from 88.2% to 0.3% of the previous week's average.

The dramatic traffic reduction sparked international speculation about the relationship between Yandex infrastructure and Russian online influence operations. Ukrainian President Volodymyr Zelensky stated on October 12 that social media had become "noticeably less hostile" following the strikes, with reduced "hate, less division and fewer provocations because there were fewer bots." However, researchers noted that Cloudflare's measurements track all automated requests—including legitimate search crawlers and monitoring systems—rather than exclusively identifying propaganda accounts. The data does not establish definitively whether Russian propaganda bots were disrupted or whether damaged infrastructure simply stopped generating routine automated traffic.

Speakers across Europe and the United States drew attention to reported declines in online activity associated with various political movements following the strikes, including Germany's AfD party, Britain's Reform UK, and pro-conservative accounts on X. Czech MEP Tomáš Zdechovský and other figures questioned whether these coincidences indicated links between Russian infrastructure and foreign political activity. No independently verified figures confirmed these claims.

The strikes occurred hours after US President Donald Trump warned that Ukraine should "damn well stop" attacking Russian oil refineries. Zelensky responded that "any de-escalation steps must be reciprocal and backed by real guarantees," stating Ukraine would cease striking Russian oil refineries if Russia stopped attacking Ukrainian energy infrastructure. Kyiv characterized the Yandex strikes as targeting infrastructure supporting Moscow's war effort. Meanwhile, Russian strikes on Ukraine continued; the State Emergency Service reported six injured in Russian attacks on four districts in Dnipropetrovsk region, and at least 20 people, including four children, were killed in Russian attacks on Zaporizhzhia on October 12.

Yandex confirmed that customer account records were not affected and stated it had agreed to expedited accommodation of client data and services with cloud providers VK Cloud, Selectel, and K2Cloud. The company noted that predicting full service restoration timing remained difficult, with engineers gradually restoring access to search, mail, maps, taxi, and AI assistant services as of October 12.
