Serverius and Fuzion are now part of Kolo, a Northern European data center platform.

Powering the Next Generation of Network Services

Carrier-neutral and edge-optimized, our sites deliver the uptime, low latency, and backbone security NSPs need—without vendor lock-in or roadblocks.

The infrastructure behind next-gen networks

From 5G rollouts to AI-powered traffic management, network performance starts with infrastructure.
