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

Colocation built to scale with you

Flexible, secure, and sustainably supported infrastructure. Designed for growth, compliance, and operational certainty.

Infrastructure that adapts

Legacy colocation often comes with rigid footprints, slow provisioning, or disconnected support teams. Kolo removes those limits.

Our modular, high-efficiency platform adapts to your evolving requirements—whether you’re scaling AI, securing regulated data, or expanding across Europe.

And at every step, you’re backed by Kolo engineers who know your setup, not outsourced ticket desks.
