Resolution criteria

This market resolves YES if, on or before December 31, 2026, at 23:59 UTC, Yandex officially confirms or reputable media outlets report that stored user data (e.g., files, databases, or account records on Yandex Disk, Yandex Cloud, Yandex Mail, or related services) was irreversibly lost, permanently deleted, or unrecoverably corrupted as a result of hardware destruction, facility damage, cyberattacks, or technical failure.

This market resolves NO if disruptions consist only of temporary unavailability, API/gateway timeouts, or service restrictions where data is retained or successfully restored from backups by the cutoff date.

Resolution will be verified using official Yandex statements, incident reports published on Yandex Cloud Status, or reporting from established news sources.

Background

In October 2026, three of Yandex's primary Russian data centers—located in Sasovo, Kaluga, and Vladimir—were damaged in a series of Ukrainian drone strikes, forcing complete or partial shutdowns across affected facilities. The strikes led to widespread service outages across Yandex Cloud, Yandex Disk, payment gateways, and third-party applications relying on Yandex infrastructure. While users experienced temporary retrieval failures and HTTP gateway errors, initial company updates did not confirm permanent data loss. Replacing damaged hardware is expected to take up to six months.

Due to a degree of subjectivity in resolution criteria I will not trade in this market.
