Yandex said a drone strike hit its data center in Kaluga on October 9 and completely disabled several modules. The company warned that some services may be disrupted and said it could not yet provide a restoration timeline; the full damage has not been determined.
Yandex said a drone strike hit its data center in Kaluga on October 9, disabling several modules and potentially disrupting some of the company’s services. The company said it was still assessing the damage and could not provide a timeline for restoring equipment operations.
In a statement obtained by Meduza, Yandex said “several modules of the data center have been completely disabled.” It warned that some services may experience disruptions, while stressing that the full scope of the damage had not yet been determined. The company also said employees were working to keep services running and assist those affected.
Yandex said it was continuing to assess the condition of its infrastructure. It thanked partners for their patience and cooperation, and users for their understanding. The company did not identify the specific equipment affected or say which services, if any, had already experienced interruptions because of the Kaluga strike.
The report came a day after a separate strike on Yandex’s data center in Sasovo, in the Ryazan region. According to the source report, a fire broke out there and the facility temporarily halted operations. No injuries were reported at the Sasovo data center, but disruptions affected some Yandex services and services operated by companies using its infrastructure.
Risks to Services Using Yandex Infrastructure
Data centers support services used by businesses and the public, so damage can affect more than the company that owns a facility. The Sasovo outage offers a recent example: disruptions there reportedly reached Yandex services and customers that relied on the site, including Russian Railways, MegaFon and several media outlets.
The possible effect of the Kaluga incident is not yet known. Yandex has warned of potential service interruptions, but has not named affected customers or confirmed a specific outage. The sequence of reported incidents also puts attention on the resilience of the company’s infrastructure and the ability to shift workloads when a facility is unavailable. The company has not said whether such transfers have occurred in Kaluga.
Yandex shares fell about 4% on the Moscow Exchange after news of the second strike on its data centers in two days, according to the source report. That movement reflects the immediate market response; it does not establish the eventual financial cost or scale of operational effects.

Two Data Center Strikes in Two Days
The Kaluga report followed the strike on the Sasovo facility overnight on October 8. The source report says a fire broke out and the data center temporarily stopped operating. While no one was injured at that facility, service disruptions were reported for Yandex and some organizations using its infrastructure.
On October 9, Kaluga Governor Vladislav Shapsha said Ukrainian drones had struck the regional capital and several municipal districts. He reported that nine people were injured in Kaluga, but did not specify which facilities were targeted. Yandex separately said its data center had been hit. The available information does not establish whether the governor’s reported injuries were connected to the data center or to another location.
The source identifies the strike as Ukrainian, but the supplied report does not include a separate Ukrainian statement or further evidence about the attack. The confirmed company update is that Yandex reported damage at its Kaluga data center and said its assessment was continuing.

Damage and Service Effects Still Under Review
The full extent of damage in Kaluga remains unknown. Yandex has not provided an inventory of disabled equipment, named services already affected, or identified customers whose operations may be disrupted. It also has not said when the damaged modules might return to service.
The link between the reported injuries in Kaluga and the data center has not been established in the supplied account. Nor does the report provide details about the strike’s circumstances, the extent of damage to other facilities, or whether the Kaluga site has stopped operating as a whole. Yandex’s warning concerns possible disruptions; it is not confirmation that all services are down.

Yandex Continues Its Infrastructure Review
Yandex said it was continuing to assess the condition of its infrastructure and that employees were working to maintain services and help those affected. The next key update would be a clearer account of which modules and services were affected, whether customers experienced outages, and when repairs or other recovery measures could restore operations.
The company has not announced a repair schedule or provided a date for its next update. Until it clarifies the impact, the scale and duration of any Kaluga-related service disruptions remain uncertain.
