Frequently Asked Questions

What is colocation?

Colocation is the outsourcing of an internal IT infrastructure to an external data center. The advantages for companies that host their infrastructure as a colocation at Neterra data centers are saving space, resources, and investments, 24/7 access control and network connectivity including physical and data-controlled protection of the IT hardware. Thanks to our colocation and managed services, companies can focus on their core business without having to maintain their own data center. 

Why you should choose colocation?

One of the main reasons why more and more companies are opting for colocation services is the large amount of investment that is required to build and operate a data centre of your own. Due to the continuous development of our professional colocation services, the advantages outweigh the potential disadvantages of outsourcing the data centre in almost every scenario. Thanks to redundancy and optional backup locations your critical data is optimally protected and always accessible.
