What happened
- A drone attack on Oct. 8 started a fire at Yandex's Sasovo data center in Ryazan Oblast and forced it to suspend operations completely.
- On Oct. 9 a strike damaged the Kaluga data center and disabled several modules, with services potentially disrupted.
- On Oct. 10 Yandex updated its user agreement to list drone and missile attacks among force majeure circumstances that could exempt it from contractual obligations.
- On Oct. 11 the Vladimir Oblast data center shut down completely after a reported drone attack, according to TASS citing the company.
Why it matters
- decision The amended force majeure clause can excuse Yandex after a drone or missile attack. Customers and counterparties have to read it as part of continuity planning.
- exposure Siting across three separate locations did not stop a sequence of strikes from reaching all three within four days. Regional spread alone is weak protection.
- precedent Zelensky's Oct. 8 remark that Ukraine responds in kind to strikes on its data centers frames the targeting as reciprocal. Operators near the front should plan for repeat strikes on either side.
Yandex changed its contract terms between the second strike and the third [15]. In our view the timing indicates the company planned for further attacks. Three sites in four calendar days [14] fits a campaign, and the Kyiv Independent places the strikes inside an expanding series of Ukrainian long-range attacks on infrastructure in Russia [11].
Dima Pirogov, head of Yandex's fintech division, opened his Oct. 11 post on X with these words: "Today, another Yandex data center was damaged," [2]. The report describes the incident as following a series of reported drone strikes that have disrupted Yandex services [12]. Yandex calls its data centers critical infrastructure and said employees were working around the clock to restore operations [8].
The public record is Yandex's own. That means Pirogov's post and TASS citing the company on the Vladimir shutdown [5]. The drone attribution is described as reported, and the Kyiv Independent does not include a claim of responsibility for these strikes.
Fire Point, a Ukrainian drone and missile maker [13], replied to Pirogov on Oct. 12: "Dima, have you tried turning it off and on again?" [4]. On Oct. 8 Zelensky described Ukraine's actions as an answer to Russian attacks on data centers in Ukraine, and told journalists: "We always respond in kind" [10].
The damage the account describes was physical. For an operator the loss of a site is an availability event whatever the cause. Which site carried the payments function, how long the outage lasted and whether traffic moved to another facility are all still open questions in the report.
What to watch
- Whether Yandex or Pirogov publishes restoration times or says which site carried the payments function.
- Whether Ukrainian officials claim these strikes, or further data center strikes follow the Oct. 8, 9 and 11 sequence.
- Whether other Russian providers amend their agreements to cover drone and missile attacks as Yandex did on Oct. 10.
