Stokab: KN5 Data Center

The KN5 Data Center, operated by AB Stokab, is located at Zinkens Väg 47 in the Södermalm district of Stockholm, Sweden. 

Situated in central Stockholm, it benefits from a high-density urban fibre network and immediate connectivity to Sweden’s largest metropolitan fiber infrastructure. Stokab is a city-owned dark-fibre network provider that has built one of the most extensive metro fibre rings in the region — KN5 effectively leverages this infrastructure to offer a strategic colocation and connectivity hub. 

Because the facility is embedded in the Stockholm metro fibre backbone, it is positioned to serve enterprise, carrier, cloud and interconnect customers looking for low-latency access, robust fiber diversity and city-centre connectivity.

⚙️ Facility Highlights

• KN5 is located within Stokab’s fibre-dense city network, enabling multiple redundant dark-fibre pathways into the building. 
• The site is listed in peer databases as a facility with numerous networks present — for example, PeeringDB lists 18 networks at KN5. 
• As part of Stokab’s infrastructure, the fibre network at KN5 is constructed underground in sub-ducts and supports highly resilient deployment conditions. 
• While detailed power and cooling metrics specific to KN5 are not broadly published, the facility forms part of Stokab’s data-centre offering designed to meet modern deployment needs in the Stockholm region.

🔐 Security & Compliance

• The facility benefits from the overarching security and network discipline of Stokab’s city-wide fibre infrastructure — including secure fibre vaults, monitored access and robust physical infrastructure components. 
• Stokab’s network is built with underground conduits, reducing exposure to physical risks such as environmental damage or unauthorized access to fibre routes. 
• Though specific certifications (e.g., ISO 27001, Uptime Tier) for KN5 are not publicly detailed, the building is located within the Stockholm Data Parks initiative, which emphasises sustainable and secure data-centre infrastructure. 

🌐 Connectivity & Carrier Access

• KN5 is carrier-neutral and well connected — PeeringDB shows multiple carriers and network operators present at the facility. 
• The location offers redundant fibre entry and dark-fibre pathways via Stokab’s metro network, enabling dual-entry routing and high availability. 
• Because it sits in Stockholm’s core fibre infrastructure, the facility provides low-latency access across the region and into major Nordic and European exchange points.
• Stokab’s role as a dark-fibre supplier means customers at KN5 can access base-layer infrastructure with flexibility to implement bespoke connectivity solutions.

💼 Who It Serves

• Carriers, network operators and telecommunications service providers seeking a metropolitan interconnect point with dense fibre presence and multiple peers.
• Cloud and hyperscale platform providers that require low-latency access and high-density fibre connectivity within central Stockholm.
• Enterprises and financial-services organisations that need a colocation site in a highly connected city-centre location with strong resilience and networking options.
• Content, media and streaming companies targeting Nordic-region reach and multiple peer networks for optimal distribution.
