Digital security today is not only about where data is stored, but also how it is transported – and who owns and controls the cables that carry it.

Data centers are a critical part of Norway’s digital infrastructure. That’s why they need to know who delivers the services, who owns the cables, and how security is maintained. This is especially important for the fiber cables leading into the data centers – and this is where dark fiber plays a particularly crucial role,” says Lars André Hjellødegård, Director of Dark Fiber at Eidsiva Digital.
Fiber that can withstand “anything”
Eidsiva Digital aims to contribute to secure digital development in Norway. For Hjellødegård, this means providing a fiber network that can endure more than standard solutions – and with Norwegian ownership.
“We have built a fiber network that can withstand digging, flooding, and attempts at sabotage.”
“The cables are buried deep and securely in the ground.”
“This ensures high uptime and good control over who has access,” explains Hjellødegård.
New Electronic Communications Act, new requirements
The new Electronic Communications Act introduces stricter requirements for how data centers document ownership and security – and how well they are prepared for crises. The authorities must know who owns the infrastructure, how it is built, and whether it is documented well enough to withstand a crisis.
“The law makes it easier for data centers to choose secure and future‑oriented solutions. Dark fiber is a strong choice here – because it offers full control and can withstand future requirements. Dark fiber from Eidsiva provides a long‑term platform with full control and the ability to meet the demands of both authorities and customers.”
A question of preparedness
Many data centers have chosen fiber solutions without knowing who owns the infrastructure or how it is built. This can become a problem when authorities require documentation of security and ownership.
– Ved å velge mørk fiber, får man ikke bare høy kapasitet og fleksibilitet – man får også en løsning som gjør det enklere å etterleve lovkrav og bygge tillit hos kundene, sier Hjellødegård.
With dark fiber, you get both high capacity and flexibility – and a solution that makes it easier to comply with regulations and build trust with customers,” says Hjellødegård.
He emphasizes that this is about making informed decisions – not only technical ones, but strategic as well.
“This is no longer just the IT manager’s responsibility. We need to think like defense chiefs and build digital preparedness – and that starts with the infrastructure we choose and the people behind it,” Hjellødegård concludes.
