Drone strikes on three Yandex data centers took Russian banking and video services offline
Ukraine hit three Yandex data centers with drones in a few days, the latest on Oct. 11 in the Vladimir region. Zelenskyy says the strikes also silenced pro-Russian bots, but the one measured figure in the coverage describes traffic from Yandex's own network.

Russian services: outages in and outside Russia; video streaming, banking, apps, websites offline. Yandex Go disrupted in Armenia, Belarus, Kazakhstan, Kyrgyzstan, Uzbekistan. Yandex's network automated traffic fell about 94% Sunday; experts trace it to Yandex's own crawler.

What happened
- The three sites were in Sasovo in the Ryazan region, the Kaluga region south-west of Moscow, and the Vladimir region east of the capital, according to Euronews.
- Services forced offline by the strikes included video streaming, banking, apps and various websites, according to Ars Technica as cited by Gizmodo.
- Radio Free Europe/Radio Liberty, as cited by Gizmodo, reported that technical experts trace that drop to Yandex's own search crawler.
- Claims of a sharp fall in online activity around Germany's AfD circulated widely after the strikes, but Euronews said no independently verified figures have emerged.
Why it matters
- Who's exposed exposure The outages reached users outside Russia as well as inside it, so a customer of any provider inherits the physical exposure of whatever sites that provider runs.
- What it limits constraint Cloudflare's count covers only traffic already labelled automated, and Gizmodo reasons that Russian operators would hide hosts abroad, so the figure cannot show the bots Zelenskyy describes.
- What doesn't add up contradiction Gizmodo says some claims conflate data centers with troll farms: the Internet Research Agency worked from a St. Petersburg office building, not a Yandex data center.
- Who has to decide decision Teams asked about the claimed bot drop before the early-November US midterms have to choose between answering with account-level data they hold and declining to comment on network-level figures.

Into Monday, Yandex Go, the taxi-hailing and delivery app, was still having disruptions in Armenia, Belarus, Kazakhstan, Kyrgyzstan and Uzbekistan, RFE/RL reported [9]. Those are five countries outside Russia.
Yandex's own statement shows how a damaged building becomes a product outage. "Operations at the data centre have been completely suspended. The remaining infrastructure resources are unstable and the platform is down," the company said on Telegram [5]. The strikes hit three regions [2]. But the company describes the platform, not only the Vladimir site, as down. None of the coverage identifies which strike took down which service, or whether Yandex had failover capacity.
Zelenskyy's claim runs from the outage to the bots. He spoke to the Warsaw Security Forum by video link [17]. He said "there was less hate, less division and fewer provocations because there were fewer bots." [18] He went on: "If they disappeared when Yandex went offline, this proves again and again that Europe is not the source of the problems." [19]
The measured figure comes from Cloudflare Radar. A 94% fall leaves Sunday's automated traffic from Yandex's network at about 6% of its average for the second half of September [14]. Euronews noted that the figures include legitimate automated traffic such as search-engine crawlers and do not establish whether Kremlin-linked social media bots were affected [3].
Users notice a calmer feed and say so. Gizmodo described the reports from Germany, the UK and the US as apparently based on vibes [12]. Teams then tell themselves the calmer feed is a measurement. Polymarket tweeted that "Activity on several major U.S. political subreddits plunges following attacks on Russian data centers," and, per Gizmodo, the tweet was unsupported [13]. An activity count tallies posts and visits without identifying who made them. Gizmodo offers a plainer reading, that a wide outage "presumably hobbled all kinds of activities, including posting" [20].
The test we'd apply to our own stack crosses two things: whether a user task depends on one site or several, and whether the user has another route to finish it. Tasks that sit on one site with no other route go first. The price is duplicate capacity in a second site. For bot claims, name the unit before believing the number: accounts or requests. The Cloudflare reading is requests from one network.
What to watch
- Whether Yandex reports the Vladimir site back in operation, and what it says about the Sasovo and Kaluga sites.
- Whether Cloudflare or any other measurer publishes account-level figures for the period after the strikes, not request counts from one network.
- Whether independently verified figures emerge for the claimed drops in activity around the AfD and Reform UK.

Ukraine has struck data centers run by Yandex three times in the last few days; the most recent strike, on Oct. 11, reportedly completely disabled a facility in the Vladimir region east of Moscow.
- [2]
The three Yandex data centres hit by Ukrainian drone strikes were in Sasovo in the Ryazan region, the Kaluga region south-west of Moscow, and the Vladimir region east of the capital, where the latest strike was reported on Sunday.
- [3]
The Cloudflare figures include legitimate automated traffic such as search-engine crawlers and do not establish whether Kremlin-linked social media bots were affected.
- [4]
Radio Free Europe/Radio Liberty noted that technical experts have pointed out the supposed drop in automated traffic comes from Yandex's own search crawler hitting websites with AS13238 HTTP requests, so it does not indicate anything about the broader volume of Russian internet traffic or what it contains.
- [5]
Operations at the data centre have been completely suspended. The remaining infrastructure resources are unstable and the platform is down.
- [6]
The Cloudflare statistic only accounts for Russian web traffic already categorized as automated; Gizmodo reasons that Russian cyber adversaries would presumably make some effort to obfuscate their traffic, including by locating hosts in other countries.
- [7]
The strikes caused widespread outages of Russian internet services, both within and outside the country.
- [8]
Russian services forced offline by the strikes included video streaming, banking, apps and various websites, according to Ars Technica.

Yandex Go, a taxi-hailing and delivery app, was still having disruptions in Armenia, Belarus, Kazakhstan, Kyrgyzstan and Uzbekistan into Monday, according to Radio Free Europe/Radio Liberty.

According to an analysis of Cloudflare Radar data, automated traffic originating from Yandex's network fell by approximately 94% on Sunday compared with its average levels in the second half of September.

In Germany, claims of a sharp decline in online activity surrounding the Alternative for Germany (AfD) circulated widely after the attacks, although no independently verified figures have emerged.
- [12]
Euronews noted that social media users in Germany, the UK and the US also claimed to see fewer bots; Gizmodo described this as apparently based on vibes.
- [13]
Polymarket tweeted that "Activity on several major U.S. political subreddits plunges following attacks on Russian data centers," an assertion that Gizmodo said didn't come with evidence.

A 94% fall leaves Sunday's automated traffic from Yandex's network at about 6% of its second-half-of-September average.

The debate comes weeks before the US congressional midterm elections in early November.

Some claims appear to conflate data centers with Russian troll farms; the Internet Research Agency operated out of a St. Petersburg office building, not a datacenter operated by Yandex.

Zelenskyy addressed the Warsaw Security Forum by video link, according to Euronews.
- [18]
there was less hate, less division and fewer provocations because there were fewer bots.
