On October 8, 2026, a widespread outage affected numerous Russian websites and online services. The disruption began at approximately 15:30 Moscow time. While initial reports suggested a link to a drone attack on a Yandex data center, the cybersecurity firm Curator later confirmed responsibility for the incident.

Curator stated that the outage occurred during technical maintenance aimed at upgrading system functionality. The company attributed the failure to human error, noting that the issue was localized within 30 minutes. The firm acts as a traffic filtering intermediary, protecting clients from DDoS attacks.

The company's client list includes major Russian organizations such as T-Bank, MTS Bank, Ozon Bank, Magnit, Sitilink, Lukoil, Avito, Rutube, PEK, and Sportmaster. When the provider's protection servers go down, users lose the ability to connect to these protected resources.

Curator, legally registered as OOO H-L-L, was founded in 2011. In 2025, the company reported a revenue of 2.2 ₽ billion, representing a 17% year-over-year growth, with a net profit of 298.7 ₽ million. Its current ownership structure involves entities based in Armenia and Cyprus.
