Ukrainian Drone Strikes Knock Yandex Data Centers Offline, Curbing Russian Bot Traffic

The report, carried by the technology news outlet TechRadar, links the disruption of automated traffic originating in Russia to the loss of capacity at more than one Yandex facility. It describes the change in bot activity as taking effect over a single night, rather than building up gradually.

TechRadar did not state how many data centers were affected, where they are located, how long they remained offline, or by what measure automated traffic declined. The outlet also did not say whether the decline persisted or how quickly services were restored.

The strikes are described in the report as having damaged facilities belonging to Yandex, the company whose infrastructure supports a large share of Russian-language internet services and, by extension, a substantial volume of the automated traffic that registers as bot activity in third-party monitoring.

Because the account comes from a single outlet, the specific figures behind the reported drop in bot traffic could not be independently verified from the information available. TechRadar's article was published with a byline from its senior security writer, whose coverage focuses on the intersection of geopolitics, cyber-warfare and business security, including state-linked threat activity and the protection of national infrastructure.

Bot traffic is used to measure the volume of automated requests reaching websites and online services, including both legitimate automated tools and malicious activity such as scraping, credential stuffing and denial-of-service attempts. A drop of the kind described would reflect the loss of the infrastructure that generates or routes a portion of that traffic, rather than a decision by any single operator to halt it.

The report did not attribute the change in bot traffic to any party other than the strikes themselves, and it did not describe any official response from Yandex or from Ukrainian authorities.
