Triolan

Triolan, also known as Тріолан, is a major internet service provider headquartered in Ukraine. The company delivers broadband connectivity to residential and business customers across several Ukrainian cities. As a provider of internet access, its core service involves maintaining network infrastructure that enables data transmission for users. Triolan operates under its primary brand name while also being recognized by its Ukrainian‑language alias. The firm’s headquarters are located in Ukraine, anchoring its operational base within the country’s telecommunications sector. It serves a geographic footprint that includes multiple urban areas, as evidenced by its ability to restore service in various cities after disruptions.

On February 24, 2022, Triolan experienced a significant cyber attack that coincided with the onset of the Russian invasion of Ukraine. The assault involved resetting critical networking devices to factory settings and disabling key network nodes, which caused widespread service outages. Restoration efforts were complicated by simultaneous physical damage to infrastructure from ongoing bombardment, requiring manual intervention by technicians. Despite these challenges, the provider managed to partially recover connectivity in several cities, though disruptions persisted for some time. Triolan publicly attributed the sabotage to hostile actors linked to the invasion and emphasized its focus on restoring network functionality. The incident highlighted the company’s role in Ukraine’s communications resilience and its capacity to respond under extreme conditions.
