The Shortcut to Oslo’s Digital Highway:
Oslo’s newest fiber network – built for high data volumes, critical services, and open access
When Eidsiva Digital acquired Hafslund Fiber in 2024, it meant more than simply taking ownership of cables in the ground. The company assumed responsibility for operating and further developing a central part of Oslo’s digital infrastructure. The network is open and carrier-neutral, designed to handle large volumes of data traffic between the city’s most important hubs.

Oslo has become one of the Nordic region’s key centers for data centers, cloud services, and digital platforms. At the same time, today’s reliance on cloud-based and centralized IT services places far stricter demands on availability, security, and physical infrastructure than ever before.
“Much of today’s value creation depends entirely on stable and predictable digital infrastructure. The network we manage is built with newer fiber, fewer splices, and conduits that in many areas are installed deeper than traditional fiber routes. This results in lower risk for outages, lower latency, and increased physical security — qualities that are essential for today’s and tomorrow’s digital demands,” says Henrik Fuglevik, Sales Director for Dark Fiber at Eidsiva Digital.
Infrastructure built for the secure transport of large data volumes
The growth of cloud services, data centers, and mission-critical digital solutions has made fiber networks a central component of companies’ risk profiles. As data increasingly resides in the cloud or in external data centers, downtime is no longer an option.
“Both businesses and private individuals expect close to 100 percent availability. That means the infrastructure must be built for continuous operation, even under heavy load, or other external circumstances which might lead to outages” Fuglevik explains.
An open and carrier-neutral network
A cornerstone of Eidsiva Digital’s approach is its role as a neutral network provider. The fiber network in the greater Oslo area is open to all market participants, including operators seeking access to dark fiber. This allows them to deliver the services they choose to their customers.
“The network should not lock anyone into a single provider or service model. Our role is to offer robust and accessible infrastructure, enabling operators, data center providers, and enterprises to build the solutions that best meet their needs,” says Fuglevik.
When redundancy and security are critical
For data centers and organizations with strict uptime requirements, physical redundancy is essential. Eidsiva Digital has therefore invested in new conduit routes and fiber paths that provide the market with more alternatives than before.
Among these is Eidsiva Digital’s route between Oslo Central Station and Rosenholm along Mosseveien, providing access to a new pathway with newly deployed fiber and low attenuation. This serves as an important supplement to existing solutions for organizations requiring increased redundancy and security between the Oslo and Rosenholm.
“Robust infrastructure is not only about capacity — it is about quality, documentation, and predictability. From day one, we have focused on building and further developing a network that will serve as a foundation for today’s and tomorrow’s digital traffic in and around the capital,” says John Philip Flaaten, Director of Delivery and Operations for Dark Fiber at Eidsiva Digital.
Part of Norway’s digital foundation
The fiber network in Oslo is tightly integrated with the rest of Eidsiva Digital’s infrastructure. This enables secure data transport beyond the capital, toward the inland region and further north, giving organizations the opportunity to geographically distribute data, services, and backup solutions.
Eidsiva Digital continuously work to develop the fiber network in and around the capital. The goal is to deliver a digital foundation built for the future.
