Yandex Data Centres Hit as Trump's Ceasefire Falters
Description
Yandex data centres in Russia were targeted and damaged by drone strikes amid ongoing conflict dynamics following an announced energy ceasefire by Donald Trump. The attacks caused significant service disruptions, including shutdowns of key data centres housing AI supercomputers and impacting multiple consumer and business services. Traffic from Yandex's network dropped sharply, indicating a severe operational impact. Yandex has not provided a timeline for restoration of affected services.

Russia struck a Kharkiv power plant hours after Donald Trump announced an energy ceasefire, while Ukrainian drones knocked out three Yandex data centres in four days. Cloudflare Radar data analysed by Valdrans shows traffic from Yandex's network falling in step with each strike, collapsing by about 94% on 11 October.

Trump announced the "energy ceasefire" on Truth Social on 11 October, saying it was effective immediately and that "both parties have agreed". As Valdrans reported earlier on Sunday, Kyiv appeared to learn of it from the post. Volodymyr Zelenskyy said Ukraine would observe a halt if Russia did, and had already offered to stop striking Russian refineries if the Kremlin stopped attacking Ukraine's grid.
- Sasovo, Ryazan region (night of 7 to 8 October). Yandex said the site was "seriously damaged" and completely shut down. Reuters reported that it houses two of the three supercomputers the company uses to develop its AI models.
- Kaluga region (9 October). Yandex said part of the site's infrastructure was out of service.
- Vladimir region (11 October).Yandex said drone damage forced a complete shutdown of the data centre. No one was hurt, but some of its services were unavailable.
In its own statement, Yandex warned customers that it was "very difficult to say" when the equipment would be running again. It listed the kinds of services affected: navigation and traffic, music and video, grocery ordering and the business tools companies use to take orders.

Technical Analysis
In October 2026, multiple Yandex data centres in Russia were hit by drone strikes, resulting in serious damage and shutdowns. The strikes occurred shortly after an energy ceasefire announcement by Donald Trump, which Ukraine appeared to learn about only after the announcement. The affected sites include data centres in Sasovo (Ryazan region), Kaluga region, and Vladimir region, with the Sasovo site housing two of Yandex's three AI supercomputers. Cloudflare Radar data showed a 94% drop in traffic from Yandex's network on 11 October, reflecting the operational impact. Yandex warned customers of service outages affecting navigation, music, video, grocery ordering, and business tools, and stated uncertainty about when services would be restored.
Potential Impact
The drone strikes caused complete shutdowns of multiple Yandex data centres, including those critical for AI development. This led to significant service outages for both consumer-facing and business services relying on Yandex infrastructure. Network traffic from Yandex dropped drastically, indicating a major disruption in availability. No casualties were reported, but the operational impact on Yandex's cloud and online services is substantial and ongoing.
Defensive Guidance
No specific mitigation or remediation is available from Yandex at this time. The damage is physical and caused by drone attacks, so restoration depends on repair and recovery efforts. Customers should monitor official Yandex communications for updates on service restoration. There is no indication of a software vulnerability or patchable issue.
