### [Yandex outage: Data shows that instead of going dark, malicious bots went on the move](https://yomu.fyi/post/yandex-outage-data-shows-that-instead-of-going-dark-malicious-bots-wen.md)

Reported drone strikes on Yandex data centers from October 7 to 11 caused network traffic to drop 99% below baseline for Yandex Search and 90% for Yandex.Cloud. Using Cloudflare Radar and Bot Management data, the analysis compared pre-event automation baselines with post-strike patterns on both ASNs. The Yandex Search ASN drop consisted almost entirely of verified search crawlers: 93.6% of its bot requests were verified, and 78.1% belonged to YandexBot. On Yandex.Cloud, vulnerability scanning fell 90% and plugin probing dropped 93%, but high-volume operations migrated to other Russian hosting providers, preserving identical JA4 fingerprints. Global bot traffic remained stable at 39.5%, demonstrating that malicious automation moves rather than disappears and that request behavior analysis is necessary to understand threats.
