Russia’s technology infrastructure has suffered another major disruption following reported drone attacks against data centers operated by Yandex. According to Cloudflare Radar, traffic from Yandex’s network fell approximately 99% compared with the previous week at around 00:30 UTC on October 11, 2026. The sharp decline coincided with the shutdown of the company’s Vladimir facility, described by Cloudflare Radar as the third Yandex data center hit since October 7.
Traffic from Yandex’s autonomous system, AS13238, had already declined approximately 35% after the strike in Sasovo. The subsequent drop was much steeper, illustrating how repeated disruptions across multiple facilities can compound the effects of an individual outage. The measurement concerns traffic observed from a particular network, however, and should not be interpreted as a 99% decline in all Yandex services or Russian internet activity.
The third Yandex data center hit by drones since Oct 7. Traffic from YANDEX (AS13238) was already ~35% lower after the Sasovo strike, then fell 99% vs. last week at ~00:30 UTC Oct 11, as its Vladimir site shut down, per the company.

Yandex operates search, cloud computing, navigation, artificial intelligence and other digital services. Interruptions to its infrastructure can affect both the company’s products and businesses that depend on its platforms. The extent of disruption to individual services, the physical damage at each facility and the time required for recovery remain unclear.
Data centers are built with redundancy, backup power and recovery systems, but a succession of geographically dispersed incidents poses a more difficult challenge than a single local outage. Restoring service can require shifting workloads, synchronizing data, replacing damaged equipment and ensuring that remaining sites have enough spare capacity.
The incidents also highlight the growing importance of physical computing infrastructure in modern conflicts. Cloud services may appear abstract to their users, yet they depend on buildings, electrical equipment, cooling systems, fiber connections and specialized servers. Damage to a concentrated computing site can ripple across many dependent applications.
AI infrastructure is particularly sensitive to such interruptions because large training clusters depend on tightly connected hardware and substantial electrical capacity. If specialized equipment is damaged, replacing it may be more difficult than restoring ordinary web hosting, especially where access to advanced technology is restricted. The available traffic figures alone do not establish whether Yandex’s AI workloads were affected or to what extent.
Cloudflare Radar offers a useful outside view of the disruption, independent of service-status announcements. Its measurements show an exceptionally severe change in network traffic, while leaving important questions unanswered about the causes of each outage, the amount of equipment damaged and the broader economic consequences.
For those watching Ukraine’s effort to challenge Russia’s much larger infrastructure base, the latest disruption offers a measure of satisfaction: it suggests that another vulnerability in the system supporting Vladimir Putin’s wartime economy has been exposed. The significance is not simply the loss of traffic on one network, but the apparent difficulty of protecting multiple technology facilities from repeated strikes. That satisfaction should be tempered by the fact that Yandex also supports ordinary civilian services, and the full consequences of the outages are not yet known.
For Yandex, the immediate task is to restore stable service. The longer-term question is whether its infrastructure can withstand further geographically distributed disruptions without another dramatic collapse in observed traffic. The episode is a reminder that the digital economy remains dependent on physical assets that can be interrupted just as surely as power grids or transportation networks.
