Frequently asked questions about colocation

What is colocation?

Colocation, also known as server hosting, is a service where businesses place their own servers, storage, and networking equipment in an external data center operated by a specialized provider. This allows companies to avoid managing physical infrastructure themselves, while still running their IT in a secure and professional environment.

The term “colocation” refers to the fact that your equipment is housed alongside other customers’ systems in the same facility. While you share resources such as power, cooling, fire protection, and connectivity, you still retain full control over your own servers.

In Sweden, colocation is widely used as a cost-effective and reliable solution for businesses that want to maintain control over their IT environment—without investing in their own data centre. In addition, colocation offers high availability, redundancy, and security, making it an attractive choice for organizations of all sizes.

Colocation is sometimes referred to as “colo” and has become a standard model for modern data centre operations. As a result, more and more businesses are moving their IT infrastructure to colocation facilities to benefit from both cost efficiency and professional management.

Is my equipment secure in a colocation data centre?

Yes—security is one of the main advantages of colocation. Our facilities in Sweden are designed to protect your equipment around the clock. Therefore, we implement multiple layers of security, including physical protection, access control systems, continuous monitoring, and advanced fire detection.

What are the benefits of colocation in Sweden?

Choosing colocation in Sweden offers several key advantages. First, your data is protected under Swedish law and GDPR, ensuring strong privacy protection and full control over how your information is handled.

Second, our data centers in Sweden are powered by renewable energy. As a result, you benefit from sustainable and environmentally friendly operations without compromising on performance or security.

Finally, Sweden’s proximity to major network hubs ensures low latency and high availability. This means your business benefits from stable performance and fast access while meeting sustainability requirements.

What types of businesses benefit from colocation?

Colocation is ideal for businesses that require high availability, data security, and full control over their IT infrastructure. Therefore, it is especially popular in industries such as finance, e-commerce, the public sector, and technology—where reliability and compliance are critical.

At the same time, colocation offers flexibility. Because the solution is scalable, businesses can easily adjust capacity as their needs grow—without making large investments in facilities or infrastructure.

In addition, colocation in Sweden is a cost-effective option for smaller businesses looking to scale, giving them access to the same professional data center infrastructure as larger enterprises.

How do Bahnhof’s data centres differ from others in Sweden?

Bahnhof owns and operates its own data centres in Sweden, with a strong focus on security, sustainability, and independence. Unlike many providers, all operations are based in Sweden, meaning both data handling and network infrastructure are governed by Swedish law and GDPR.

Furthermore, all Bahnhof data centres are powered by 100% renewable energy, ensuring environmentally sustainable and energy-efficient operations. This means customers benefit not only from high technical performance but also from environmental and legal assurance.

As an additional mark of quality, Bahnhof is certified with Based in Sweden—a designation that guarantees Swedish ownership, local operations, and that customer data is never stored outside the country. This certification reflects strict standards for data sovereignty, transparency, and secure data handling.

Finally, Bahnhof operates its own infrastructure and network capacity, providing full control across the entire chain—from connectivity to server operations. As a result, we can ensure high availability, low latency, and maximum data security across all our colocation data centres in Sweden.

Can I customize my colocation solution?

Absolutely. At Bahnhof, you can tailor your colocation solution to match your specific business needs. You can choose everything from shared rack space to private cabinets—or even a fully dedicated cage.

In addition, we offer flexible options for power, cooling, and networking, ensuring that every customer receives an optimized, secure, and scalable operating environment.

In short, you retain full control over your infrastructure while benefiting from Bahnhof’s high security standards and sustainable operations in Sweden.
