Ukrainian drones ignite fire at Yandex’s largest data centre and Sasta plant in Russia’s Ryazan region
Ukrainian drones hit an industrial site in the city of Sasovo, Ryazan Oblast, setting off a large fire at a complex that includes Yandex’s largest data centre and the Sasta machine‑tool plant and causing widespread outages in Yandex services.
A Ukrainian drone strike on the city of Sasovo in Russia’s Ryazan region has brought the war directly into the country’s digital and industrial infrastructure. The overnight attack targeted a site that houses the Sasta machine‑tool plant and a major data centre owned by Yandex, Russia’s leading internet company, triggering a large fire and service disruptions for users.
Reports said Ukrainian drones struck the Sasta plant complex in Sasovo, where both the manufacturing facility and the Yandex data centre are located. The data centre is described as the largest operated by Yandex, supporting its cloud infrastructure and other services and hosting tens of thousands of servers. After the strike, a significant fire broke out and widespread outages were reported across Yandex platforms.
There was no immediate official information on casualties or a full accounting of physical damage to either the industrial plant or the data centre. Visual material and online reports pointed to a major blaze, with emergency services present at the site. Russian authorities had not yet issued a detailed assessment or public attribution for the attack.
Ukrainian sources highlighted the role of the Sasta facility in Russia’s defence‑related industry, stating that the plant produces advanced metal‑working machine tools, including multi‑axis machining centres, turning‑milling complexes and heavy equipment used in the defence sector.
For Russians who rely on Yandex for everyday services, the most direct impact was digital. The company’s search, maps, ride‑hailing, delivery, and cloud products depend on large data centres like the one in Sasovo. A hit on the largest of these facilities can quickly translate into interrupted apps and business systems for organisations that use Yandex’s infrastructure.
The strike also has implications for workers and local communities tied to the Sasta plant. Machine‑tool factories supply equipment essential to precision manufacturing across sectors, including defence and energy. Damage to such a site can slow equipment deliveries and maintenance for other plants that depend on its output, even if they are located far from Ryazan.
Targeting a major data centre and a machine‑tool producer in a single operation illustrates how Ukraine is aiming at both information infrastructure and industrial capacity deep inside Russia. It adds another layer of demand on Russian air defences already tasked with protecting military bases, energy sites and logistics hubs across a wide territory.
Key signals to track now are how quickly Yandex restores full service, whether there are confirmations of data loss or hardware destruction at the Sasovo facility, and any indications from Ukrainian or Russian sources that similar digital and industrial targets are likely to be hit again.
