SATLINE Completes Tier III Infrastructure Upgrade

We are pleased to announce the successful completion of a major core infrastructure upgrade at our primary hub in Vilnius. This project aligns our core systems with Tier III standards under the Uptime Institute’s Tier Classification System—the international gold standard for data center performance.

This upgrade significantly strengthens our resilience by enabling concurrent maintainability and eliminating single points of failure across critical systems. Importantly, all improvements were implemented without a single minute of customer-impacting downtime.

What We Upgraded

• Power redundancy – The power infrastructure was upgraded from a single generator to two fully redundant generators, eliminating single points of failure entirely.
• Expanded UPS capacity – UPS systems were doubled in capacity, ensuring extended runtime and improved load handling during power events.
• Modernised cooling – HVAC and cooling systems were overhauled to be fully redundant and energy-efficient, improving both thermal stability and long-term operational efficiency.
• Tier III–aligned design – The overall architecture now follows Tier III principles, enabling concurrent maintainability and higher availability.

All infrastructure improvements were implemented without a single minute of customer-impacting downtime.

What This Means for Our Clients

The transition of our Vilnius core from Tier II to a Tier III-aligned design transforms our infrastructure from partially redundant to fully resilient. In practical terms, this delivers:

• Elimination of single points of failure across all power and cooling systems.
• Concurrent maintainability, allowing any infrastructure component to be serviced without impacting live operations.
• Improved availability and fault tolerance, significantly reducing operational risk.
• Greater scalability, supporting future growth and higher service demands.

For SATLINE’s clients, this means guaranteed continuity—even when infrastructure is being actively serviced or upgraded.

“Our Tier III–aligned upgrade has already delivered measurable gains in operational resilience. Building on a 10-year track record of 100% uptime across both network and power, we have further strengthened our infrastructure through fully redundant power generation, increased UPS capacity, and modernised cooling. The result is a system that not only sustains uninterrupted service, but is engineered to exceed the reliability benchmarks our customers depend on.” – Simas Mockevicius, Senior Network Engineer, SATLINE.

Looking Ahead

This milestone is part of our ongoing strategy to invest in infrastructure that meets the uptime demands of satellite communications and critical connectivity. With our European core now fully resilient, we have confirmed expansion into Asia as our next strategic step—extending our carrier-grade infrastructure to a region experiencing rapid growth in satellite connectivity demand.
