Yandex Data Centres Hit as Trump's Ceasefire Falters
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.
All HTTP requests from Yandex AS13238 as a share of the period's maximum; the dashed line is the previous week. At 18:00 UTC on 11 October the reading was 7%, against 82.6% at the same time a week earlier. Source: Cloudflare Radar (CC BY 4.0).
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.
