In a letter dated October 12, Multon Partners told retail chains that its labeling system had been down since 04:00 Moscow time on October 11, after the data centers failed. Services provided by UTrace, the labeling provider, were unavailable, the company said, warning of possible delays in shipping labeled goods and asking retailers not to fine it for late deliveries or other violations.
Multon Partners said its partners were restoring access and moving data to backup hosting.
PepsiCo Holdings reported problems a day earlier, on October 11. It said a data center malfunction had interrupted the exchange of data between its labeling system and Chestny Znak, the national track-and-trace system, preventing it from processing electronic universal transfer documents. The company asked retailers to accept goods on paper documents and promised to issue all electronic transfer documents within 48 hours, saying that if they did not arrive, the products should be returned in the usual manner.
Retailers surveyed by Fontanka said deliveries were continuing and that there was no shortage so far. A source at one of the chains described the situation: "We accept the goods and sell them, but everything is in manual mode." Other manufacturers and suppliers have not reported similar disruptions.
Overnight on October 11, drones struck a Yandex data center in the Vladimir region, bringing it to a complete halt. Users reported problems with Alice, Search, Maps, Taxi, Mail and other company services, and passengers were unable to leave Pulkovo Airport that night. Earlier, on October 8 and 9, drones attacked Yandex data centers in Sasovo in the Ryazan region and in Kaluga.
According to Kommersant, the company will not be able to replace the damaged equipment quickly after the strikes, with deliveries of new hardware taking up to six months. Fplus, an electronics manufacturer, told the outlet that Yandex would not be able to replace the affected equipment before the end of the year, calling an order for significant volumes of equipment in the coming months "utopia." Market participants surveyed by Kommersant expect a short-term rise in equipment prices and, as a result, more expensive cloud services for Yandex clients.
In total, according to Kommersant, Ukrainian forces attacked three of Yandex's six known data centers. By the evening of October 11, the company said its products were "gradually returning to operation after the outage," but some service functions remained unavailable.
The strikes were reported to have disrupted Yandex Pay, Yandex Games, Yandex Go and Kinopoisk. Users also complained of problems accessing the resources of the Vkusno — i tochka and KFC chains, Lamoda, Sports.ru, Dodo Pizza, Pyaterochka, Magnit, Lenta, Pulkovo Airport, Flowwow, Cian and the internet provider Dom.ru.
The Telegram channel T-Invariant claims that all three of Yandex's supercomputers may have been disabled by the strikes on the data centers in the Ryazan region and Kaluga.
