BREAKING A third Yandex data center is now down after a strike by Ukraine’s Defense Forces, and the outage map reads like a map of Russia’s digital nervous system collapsing. Yandex Cloud has lost more than 80 core services across its availability zones. Not minor tools. The infrastructure layer itself. Compute and network: Compute Cloud, Virtual Private Cloud, Managed Kubernetes, Cloud Functions, load balancers, Cloud DNS. Data and storage: Object Storage, managed PostgreSQL, ClickHouse, MySQL, Valkey, YDB, OpenSearch. AI and analytics: YandexGPT API, SpeechKit, Vision OCR, DataLens, SpeechSense, Yandex AI Studio. Development and security: Managed GitLab, SourceCraft, Identity Hub, Key Management Service, SmartCaptcha, Smart Web Security, SIEM. Corporate tools: Tracker, Wiki, Forms, Cloud Desktop, Search API, Cloud Console, Billing. Yandex Home, Yandex Music, and Telemost are also down. The strategic layer is worse than the outage list. Sasovo hosts two of Yandex’s three supercomputers used to train YandexGPT. Their status remains unknown. If those machines are damaged, Russia loses the hardware behind its main domestic AI push, along with its cloud capacity. Moscow built a sovereign digital stack over the years to isolate itself from Western infrastructure. That isolation now means an outside provider cannot absorb the failure. The cloud is burning, and the replacement is a queue for VK Cloud.
