Balancing control and growth in physical infrastructure

Modern enterprises demand more than cloud flexibility – they need the stability and control that only dedicated hardware can provide. Colocation combines full ownership of your infrastructure with the reliability, sustainability, and scalability of a managed data center environment.

Run your systems in Nordic facilities powered by 100% renewable energy, engineered for uptime, and connected to a carrier-neutral network ecosystem. We handle power, cooling, security, and on-site operations, while you retain total control of your hardware, network design, and workloads.

Whether you’re extending a hybrid or multicloud architecture, deploying high-density AI clusters, or consolidating enterprise systems, our colocation platform provides the flexibility to scale seamlessly and the confidence of enterprise-grade protection backed by strict SLAs.

True infrastructure freedom lies in balance – owning your hardware while operating on a platform built for growth. With colocation, you gain the control, efficiency, and resilience to evolve your business without compromise.

Frequently asked questions

What is colocation?
expand_more

Colocation is a service that allows you to place your own servers and equipment in a secure, professional data center. You retain full ownership and control, while we provide power, cooling, connectivity, and physical security.

Can I access the data center to manage my servers?
expand_more

If you rent a full rack, you’ll receive a personal access card and key, allowing you to access your servers whenever needed. For single server colocation, a Glesys staff member must be present during access.

When can I access my servers?
expand_more

Rack customers have 24/7 access to the data center every day of the year. For single server colocation, access is available during office hours.

What kind of Internet connectivity do you offer?
expand_more

We operate as an independent ISP with over 10 upstream connections and more than 100 Gbit/s in available capacity. We also exchange traffic with other ISPs at multiple interconnection points across Sweden.

Can I get redundant connectivity to my rack?
expand_more

Yes, we offer redundant network connections. We can also assist with transport to other ISPs beyond Glesys to further increase redundancy.

Can I get help restarting or reinstalling my server?
expand_more

Absolutely. We offer Remote Hands support, and we can also provide a temporary KVM kit, allowing you to manage your server remotely regardless of its current state.
