Overview
- Ukrainian drone strikes on Yandex data centers earlier this week caused major outages to Yandex Search and Yandex.Cloud, producing sharp drops in traffic observed by Cloudflare.
- Cloudflare recorded roughly 99 percent and 90 percent declines in traffic from Yandex Search and Yandex.Cloud and measured falls in some automated request categories.
- The company cautioned that its Radar metric tracks automated HTTP requests such as search crawlers and scripts, so a drop in that metric does not show account activity on platforms like X or Reddit.
- Cloudflare and independent researchers found that some malicious operators quickly migrated services to other hosts, and monitoring groups said they see no clear evidence that known Russian troll clusters were taken offline.
- The strikes show kinetic attacks can disrupt search indexing and cloud services and may temporarily alter online noise, but assessing effects on disinformation requires platform-level data and ongoing monitoring.
