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

Open, fast and flexible network access

Connect to clouds, carriers, and IXPs on your terms. Kolo’s fully carrier-neutral platform gives you the architectural freedom to adapt, expand, and optimize your network without vendor lock-in or hidden complexity.

The interconnection bottleneck

Today’s digital infrastructure relies on more than just bandwidth. Low-latency application performance, secure hybrid cloud access, and resilient data flow require an interconnection strategy built for flexibility and scale. Legacy carrier models often limit control and speed and can’t keep up with modern workload demands.

You need:

  • Built-in redundancy, failover, and the ability to scale across platforms
  • Fast, direct paths between your infrastructure and your cloud environments
  • Full control over carrier and cloud relationships, without lock-in

What you get

Our interconnection platform supports a wide range of deployment models and performance needs, whether you’re peering with carriers, connecting to cloud services, or linking between sites.

Carrier-neutral colocation

Full provider flexibility without lock-in, giving you true choice across networks and carriers.

Cloud connectivity

Private on-ramps to AWS, Azure, Google, and others for secure, low-latency cloud access.

Internet exchange access

Direct connections to major IXs for efficient, high-speed global routing.

High-capacity transport

DWDM services for metro and long-haul connections with scalable bandwidth.

Layer 2 and layer 3 services

Ethernet and IP connectivity options tailored to your architecture needs.

On-demand cross-connects

Fiber and copper cross-connects available quickly to adapt to changes in your environment.

NOC-as-a-Service

24/7 monitoring, triage, and carrier coordination to reduce your operational workload.

How it works

1. Define your interconnection setup

Choose your preferred topology – direct cloud links, IXP access, or DWDM transport for metro and regional connections

2. Deploy carriers and service

Provision the providers you need through our neutral meet-me rooms or cloud exchange partners.

3. Establish secure, low-latency routing

Configure for failover and throughput to match application and compliance requirements.

4. Monitor and optimize for performance

Use Kolo’s remote tools or NOC support to maintain availability and adapt as your needs evolve.

Optional: NOC-as-a-Service

Extend your team with 24/7 expert monitoring and response.

For organizations that need deeper visibility or reduced operational overhead, KOLO’s NOC-as-a-Service extends your team with hands-on support.

Our network operations center provides first-line monitoring, incident triage, and escalation coordination, accelerating response and easing internal workload.

Connect where it counts

Your infrastructure depends on reliable, adaptable connectivity. Kolo gives your network the performance, reach, and expert support to grow without constraints.
