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, while the extent of the damage and restoration timeline remain unknown. The report follows a strike on a separate Yandex data center in Sasovo the previous night.
Yandex said on October 9 that a drone strike hit its data center in Kaluga, Russia, completely disabling several modules and potentially disrupting some of the company’s services. The report marks the second strike on a Yandex data center in two days; the company said the damage assessment is continuing and it cannot yet give a timetable for restoring equipment.
In a statement obtained by Meduza, Yandex said the strike had left several data center modules completely disabled. The company warned that some services could experience disruptions, but did not identify which services were affected or report the full extent of the outage. It said the overall scope of the damage had yet to be determined.
Yandex said it was continuing to assess the condition of its infrastructure and thanked its partners for their patience and cooperation, as well as users for their understanding. The company also said employees were working to keep services running and assist those affected. It cautioned that it was too difficult to provide a restoration timeline while the equipment assessment was underway.
Yandex shares fell about 4% on the Moscow Exchange after news of the Kaluga strike, according to the report. That market move came after a separate drone strike hit a Yandex data center in Sasovo, in the Ryazan region, overnight on October 8. A fire broke out there, the facility temporarily halted operations, and some services hosted on its infrastructure were disrupted.
Two Strikes Put Yandex Infrastructure at Risk
The reports point to two incidents at separate Yandex data centers within two days, raising immediate concerns about service reliability for the company and organizations that rely on its infrastructure. Yandex has warned of possible disruption from the Kaluga damage, but has not yet said which services or customers could be affected.
The earlier Sasovo outage illustrates how a data center incident can extend beyond the operator. According to the report, disruptions there affected some Yandex services and services used by other organizations, including the websites of Russian Railways, MegaFon and several Russian media outlets. Whether the Kaluga strike has produced comparable knock-on effects is not yet known.
The reported share-price decline is a sign of an immediate market reaction, not a measure of the strike’s eventual financial cost. That cost, as well as any longer-term operational impact, depends on how much equipment was damaged and how quickly it can be restored.

Sasovo Strike Preceded Kaluga
The first incident described in the report took place overnight on October 8, when Ukrainian forces struck a Yandex data center in Sasovo, in Russia’s Ryazan region. A fire broke out and the facility temporarily stopped operating. The report said no one was injured in that incident.
Service interruptions at Sasovo extended to some users of Yandex’s infrastructure, including the Russian Railways and MegaFon websites and several Russian media outlets. The Kaluga incident was reported the next day. On October 9, regional governor Vladislav Shapsha said Ukrainian drones had struck Kaluga and several municipal districts. He reported nine people injured in Kaluga but did not specify which facilities had been targeted.
Yandex’s statement identifies its Kaluga data center as having been hit. The governor’s comments, as reported by Meduza, describe drone strikes in the region but do not independently identify the data center as a target.
“Several modules of the data center have been completely disabled.”

Damage Scope and Outages Unconfirmed
The extent of damage in Kaluga remains unclear. Yandex has said several modules were disabled but has not disclosed how many modules were affected, what equipment was damaged, or whether the facility as a whole has stopped operating. The company has also not named the services experiencing disruption or confirmed the scale of any impact on customers.
It is also not clear from the available reporting whether the nine injuries mentioned by Governor Shapsha were connected to the data center strike. He did not specify which facilities had been targeted, and the report does not establish a link between those injuries and Yandex’s infrastructure. No restoration estimate is available.

Yandex Continues Infrastructure Assessment
Yandex said it is continuing to assess the condition of its infrastructure and working to keep services running. The company has not announced when it will complete that assessment or when damaged equipment might return to operation. Users and partner organizations may receive clearer information as Yandex identifies which systems are affected.
The near-term indicators are any further Yandex service notices, updates on the condition of the Kaluga facility, and confirmation of whether outages have spread to organizations that use its infrastructure. Until the company provides those details, the full operational impact and recovery schedule remain undetermined.
