Drone attacks on October 8-9, 2026 damaged infrastructure at Yandex's Kaluga data center, taking multiple server modules fully offline and prompting service interruptions without casualties, according to Russian sources including Fontanka and VC.ru.
Details on Kaluga and Ryazan impacts
The Fontanka report specifies that the Kaluga facility spans approximately 130,000 square meters with 3,800 server racks, each carrying a 15 kW load. VC.ru adds that part of Yandex services may operate with interruptions due to the damage, while emergency crews and company specialists remain on-site assessing the full scope of harm. Separately, VC.ru notes that on October 8, 2026, another Yandex data center in Ryazan was struck by drones, causing a fire and disrupting services such as Cian and Twinby.
What remains undisclosed
The original material highlights that the total extent of physical damage to modules and equipment has not been revealed, nor has an estimated timeline for full capacity restoration. It also states that it is unknown whether stored data suffered loss or corruption, or if Russian authorities will launch an investigation into the attacks.
Other topics in the coverage batch
Among the newly provided sources from Russia, Timor-Leste, and Belarus, one item from Tatoli (Timor-Leste) covers a separate subject: a U.S. Embassy-funded English training program for Timor-Leste officials aimed at strengthening regional engagement and ASEAN chairship preparation, with no connection to the Yandex incident or drone attacks mentioned in its text.
What still isn't known
Beyond the undisclosed damage details and restoration timeline, the material does not clarify if the Ryazan data center incident involved the same drone attack campaign as Kaluga, or provide specifics on the nature of the service interruptions beyond named platforms like Cian and Twinby.
