Yandex’s Vladimir data centre was fully shut down on 11 October 2026 after a drone attack, disrupting both internal systems and user-facing applications.[^4]

The outage took the company’s entire ru-central1-a operating zone completely offline.[^3] Russian state news agency TASS confirmed the facility had been fully stopped.[^5]

Yandex issued a statement the same day attributing the service failure to a fire at an unrelated data centre in Sasovo, Ryazan Oblast. That statement did not reference a drone attack.[^6]

Also on 11 October, the Russian Ministry of Defence announced it had struck a data centre in Odesa, Ukraine. The ministry claimed this Tenet facility was used by the Ukrainian military for intelligence collection and processing. Two separate international outlets carried that claim.[^1][^2]

No public account has established any link between the strike reported in Ukraine and the outage inside Russia. No further status updates for the Vladimir facility had been published at time of filing.
