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

  • 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.
  • 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.
  • 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.
  • 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 [5]. 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 [6]. 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 [8].

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.
