Yandex said a drone strike hit its data center in Kaluga on October 9, disabling several modules and potentially disrupting some services. The incident came a day after a strike disrupted operations at the company’s data center in Sasovo; the full damage in Kaluga and a repair timeline remain unknown.
Yandex said a drone strike hit its data center in Kaluga on October 9 and completely disabled several modules, warning that some of its services could be disrupted. The company said it was still assessing the damage and could not give a timetable for restoring equipment, after a separate strike disrupted operations at its Sasovo data center the previous day.
In a statement obtained by Meduza, Yandex said several modules at the Kaluga facility were completely disabled. It warned that the incident could affect some Yandex services, but did not identify which products or explain how many users might be affected. The company said the full extent of the damage had not yet been determined.
Yandex said it was continuing to assess the condition of its infrastructure. It thanked business partners for their patience and cooperation, and users for their understanding. The company also praised employees working to keep services running and assist people affected by the incident.
The report came after an overnight drone strike on October 8 at a Yandex data center in Sasovo, in Russia’s Ryazan region. A fire broke out, and the facility temporarily halted operations. Meduza reported that disruptions affected some Yandex services and services belonging to companies that relied on the Sasovo infrastructure, including Russian Railways, MegaFon and several Russian media outlets.
Two Strikes Put Data Services at Risk
The reported damage matters beyond Yandex’s own products because data centers can host or support services used by other organizations. The Sasovo incident showed that an interruption at one facility can affect businesses and public-facing services that depend on its infrastructure. Whether the Kaluga damage will produce similar effects is not yet clear.
For customers and partner companies, the immediate concern is whether disruption spreads or continues while equipment is assessed and repairs are planned. Yandex has warned of possible service interruptions, but has not published a list of affected services or confirmed the scale of impact. That leaves users and dependent organizations without a clear picture of which systems may be affected or for how long.
Meduza reported that Yandex shares fell about 4% on the Moscow Exchange after news of the second strike on its data centers in two days. That market movement indicates an immediate investor response, but does not establish the eventual financial cost of the damage or its effect on the company’s operations.

The Sasovo Strike Came First
The Kaluga report follows a separate incident in Sasovo on the night of October 8. According to Meduza, a fire broke out after drones struck the Yandex data center there, and the facility temporarily stopped operating. No injuries were reported at the Sasovo data center, while disruptions were reported for some Yandex services and organizations using its infrastructure.
On October 9, Kaluga Governor Vladislav Shapsha said Ukrainian drones had struck the regional capital and several municipal districts. He said nine people were injured in Kaluga, but did not specify which facilities had been targeted. Yandex’s statement identified its data center as having been hit; the governor’s remarks, as reported by Meduza, did not identify the site.
The two reports concern separate facilities in different regions and on consecutive days. The available information does not establish whether the strikes were connected beyond both affecting Yandex data centers. The account of the Kaluga incident is based on Yandex’s statement as cited by Meduza; the reported injuries and drone activity there were attributed to the regional governor.
“Several modules of the data center have been completely disabled.”

Damage and Service Effects Unknown
Yandex has not said how many modules were disabled, what equipment was damaged, or how much of the Kaluga facility’s capacity is unavailable. It has also not identified the services that could be disrupted, provided an estimate of affected users, or said whether any partner companies have experienced outages linked to this incident.
The available reporting does not provide an independent assessment of the damage or clarify the precise circumstances of the strike. Shapsha’s statement about drone attacks and injuries in the region did not name Yandex’s facility. Yandex has not given a repair timeline, saying it is too early to estimate when equipment operations can be restored.

Yandex Continues Its Damage Review
Yandex said it is continuing to assess the condition of its infrastructure and that employees are working to keep services running and help those affected. The company has not announced a date for restoring the disabled modules or said when it will provide its next update.
The next useful information for users and business partners will be a clearer account of which services are affected, whether interruptions are ongoing, and how long repairs may take. Until Yandex releases those details, the scope and duration of disruption at Kaluga remain uncertain.
