Bahnhof AB: Thule Data Center

Located at Tunnelgatan 2, Stockholm (111 37), the Thule Data Center is nestled within the historic Brunkebergsåsen rock formation in the heart of Sweden’s capital. Operated by Bahnhof AB, this facility offers a highly secure, centrally located colocation and infrastructure environment, ideally positioned for enterprises seeking low-latency access in the Nordics and robust connectivity across Europe. With its urban centre placement and strong infrastructure credentials, Thule serves as a premium option for organisations prioritising proximity, performance and scalability.

⚙️ Facility Highlights

• Three-layer perimeter security and protection class 3 according to SSF 200 standard. 
• Power infrastructure: three UPS units (Eaton 9395) totalling ~1.9 MW output, redundancy ratio 3N+2. 
• Generator backup of approximately 2.6 MW via three MTU V16 units with N+1 redundancy. 
• Dual cooling system comprising three heat pumps (500 kW each) plus secondary cooling via district-cooling hookups; the facility taps into the city’s energy reuse via Stockholm Exergi to recover server-hall heat and integrate with district heating. 

🔐 Security & Compliance

• Certified for Protection Class 3 under SSF 200, and Alarm Class 3 under SSF 130. 
• 24/7 monitoring, camera surveillance across all areas, card-key & biometric access control, full logs retained for at least six months. 
• Fire-suppression using advanced systems: very-early smoke detection (VESDA), gas-based suppression (Argonite in halls 1-3, Novec 1230 in hall 4) and water-leak detection.
• Operates on 100% renewable electricity (as part of Bahnhof’s environmental commitment) and offers infrastructure recognised for energy-efficiency. 

🌐 Connectivity & Carrier Access

• Situated in central Stockholm, with strong fibre-network presence and direct access to major carriers and internet exchanges via Bahnhof’s own network. 
• Carrier-neutral colocation environment: the facility supports colocation, cross-connects, transit and inter-cloud connectivity in a network-dense urban setting. 
• Its strategic central location means very low latency to local enterprises, cloud providers, content networks and Nordic/European endpoints.

💼 Who It Serves

• Enterprises, SaaS-providers and cloud operators requiring a premium Stockholm-city data centre with high security and low latency.
• Network carriers, IX operators and service providers needing central-city-based interconnection and carrier-neutral infrastructure.
• Mission-critical deployments – financial services, media, legal/compliance-driven organisations – looking for robust infrastructure in Sweden.
• Organisations with sustainability mandates, given Thule’s energy-efficiency credentials and renewable-power sourcing.
