Colocationix gmbh: ColocationIX DC5

ColocationIX DC5 is located at Zwinglistraße 31, Bremen, Germany, and is operated by ColocationIX GmbH. Positioned in the Bremen metropolitan region, this facility benefits from strong connectivity to Northern Europe’s fibre and internet-exchange ecosystem and proximity to the German seaport and transport infrastructure. Designed as a high-security, high-availability data centre (built in a former nuclear-shelter shell and engineered to “Klasse 4”/EN 50600 Class 4 standards), the site offers a compelling option for enterprises and critical-infrastructure customers requiring premium resilience and German-jurisdiction data hosting.

⚙️ Facility Highlights

• Built to design specification “Klasse 4 / EN 50600 Class 4” (comparable to TIA-942 Tier 4) for maximum availability. 
• Located within an ex-atomschutzbunker (former nuclear shelter) with 2-metre thick steel-reinforced concrete walls, providing extraordinary structural security. 
• CO₂-neutral energy operation and very high energy efficiency (PUE ~1.1 claimed) leveraging geothermal cooling and other energy-optimised technologies. 
• “Erdbebenfrei” (earthquake-free) site rating according to operator materials, enhancing risk mitigation for seismic events. 
• Premium 19″ racks (42 HE) available in different configurations for colocation, including private cloud/housing options. 

🔐 Security & Compliance

• The facility is certified to ISO 27001 (Information Security Management) and ISO 27701 (Privacy Information Management) standards. 
• Designed and operated in compliance with KRITIS (Germany’s critical infrastructure) guidelines. 
• Physical access controls include trifold authentication (PIN/code + access card + biometric), detent-door mantrap, 200+ CCTV cameras, and constant on-site guard presence. 
• Permanent oxygen-reduction system to mitigate fire risk and ensure integrity of hardware within the vault-style containment. 

🌐 Connectivity & Carrier Access

• Carrier-neutral facility with multiple fibre-entry routes and diverse feed infrastructure supporting high-availability connectivity. 
• Network peer information: AS61955 (ColocationIX) is present on AMS-IX, BCIX, BREM-IX, CentralIX and others, indicating robust exchange/peering capability. 
• Internet-Exchange proximity (including Bremen-IX) and direct links to major European IXPs enhance low latency and interconnection opportunities.
• Connectivity services include 1 Gbit/s, 10 Gbit/s and 100 Gbit/s uplinks, as noted in their colocation offering. 

💼 Who It Serves

• Enterprises and mid-sized companies seeking a high-security, German-jurisdiction data centre for colocation or disaster-recovery hosting. 
• Organizations in regulated sectors such as banking, insurance, critical infrastructure (KRITIS), logistics and e-commerce that require infrastructure with advanced compliance and resilience features. 
• Service providers, content distribution networks (CDNs), and connectivity-centric platforms that value dense interconnection capabilities and carrier neutrality.
