Colocation services for critical infrastructure
Colocation is Walhalla’s service for hosting your own servers and network equipment in our data centre Tier IV in Castellón, Spain. The equipment remains yours. We provide the space, power, cooling, physical security, connectivity if you need it, and 24/7 operations.
1The service
What is colocation in a data centre?
Data centre colocation, also known as housing or server colocation, means installing your own servers in the halls of a specialist provider instead of keeping them in the office. The company keeps ownership and control of the equipment, and the provider guarantees the conditions that equipment needs to run without interruption.
2The options
Colocation options
The service adapts to the size of each project:
- Individual rack units for a few servers.
- Full racks of 47U (42U usable by the customer, expandable on request), with lock and access control.
- Dedicated suites for deployments that need physical isolation.
Each rack receives dual power feeds from independent branches, up to 48 A per path (around 11 kW per rack), and a dual fibre link over separate routes to the communications rooms.
Change where the servers are and see who takes care of what.

A carrier-neutral facility
The data centre is carrier-neutral. It has two physically separate meet-me rooms (MMR) and its own autonomous system (AS30937). You can contract connectivity from Walhalla, bring your own carrier or combine both.
Castellón, as a primary or backup site
The facility is located in the Universitat Jaume I Science and Technology Park in Castellón, connected by motorway, by high-speed rail to Madrid and by direct train to Barcelona. It works as a primary data centre or as a secondary site for companies that already have their infrastructure in a large city and need geographically separate backup.
Service levels by contract
The service level agreement is part of every contract:
- 99.995% availability of power supply and cooling.
- 99.900% for connectivity contracted with Walhalla.
- Response within 1 hour and target resolution within 4 hours for priority 1 incidents.
- Penalties in the form of credits on the monthly fee if the committed availability is not met, on request by the customer and under the SLA.
Downtime is counted from the moment our monitoring detects it or you report it to us, whichever comes first. You do not need to open a ticket for the clock to start.

Frequently asked questions
Who owns the equipment?
The customer, at all times. Walhalla provides the facility, power, cooling, connectivity and operations, acquires no rights over the hosted equipment and does not access its content.
Can I physically access my equipment?
Yes. Access is requested through the ServiceDesk and carried out by the staff you have authorised, with identification at the entrance. In an emergency, fifteen minutes’ notice is enough.
What requirements must my equipment meet?
Dual power supply with C13/C14 connectors, front-to-back cooling and 19-inch rack-mountable format. For single-PSU equipment there is the option of an STS switch, although it leaves single points of failure outside the general service level agreement.
What happens when the contract ends?
There is a thirty-day transition period with technical assistance, handover of the network and connection configuration for the service and removal of the equipment by the customer or their carrier, by appointment.
Shall we talk about your project?
Tell us your name, company and phone number, a short description of the project and the space and power you estimate. A member of our sales team will get back to you.
