Colocationix gmbh: ColocationIX DC0

ColocationIX DC0 is located at Wachtstraße 17-24 in Bremen, Germany, operated by ColocationIX GmbH. The facility occupies a unique strategic position: housed in a former high-security bunker with two-metre thick reinforced concrete walls, the site offers a “data-fortress” environment in the heart of Bremen’s network hub. Its location provides excellent connectivity to Northern Germany and the broader European network-backbone, making it particularly well placed for organisations needing robust colocation infrastructure, German-jurisdiction operations, and access to multiple carriers and Internet exchanges. Adding to the strategic significance, the facility emphasises sustainability and energy-efficiency, appealing to companies with both operational resilience and ESG concerns.

⚙️ Facility Highlights

• Built inside a former atom-shelter/“Zwinglibunker” structure, offering extremely robust physical protection via two-metre thick steel-reinforced concrete walls.

• Certified to ISO 27001 (information security management) and ISO 27701 (privacy extension). 
• CO₂-neutral operations with energy-efficiency rated “A+++” and claimed PUE (Power Usage Effectiveness) value around 1.1. 
• Utilises a highly efficient cooling system including geothermal components. 
• Offers colocation, server-housing and private-cloud ready infrastructure for midsize to enterprise customers. 

🔐 Security & Compliance

• Multi-factor biometric and chip access with trip-factor authentication (code + chip + biometrics) for entry. 
• 24/7 manned on-site security, extensive CCTV coverage (200+ cameras) and oxygen-reduction fire/prevention systems in the bunker.

💼 Who It Serves

• Organisations in Germany and Europe requiring high-security, high-compliance colocation (e.g., legal, financial, critical infrastructure) — thanks to the bunkerised facility and KRITIS-ready architecture.
• Enterprises seeking sustainable, energy-efficient infrastructure, given the CO₂-neutral claim and PUE ~1.1.
• Network- and cloud-centric businesses needing carrier neutrality, peering and interconnection capabilities (ISPs, CDNs, peering hubs).
• Midsize to large companies looking for private cloud or hybrid cloud hosting with German jurisdiction and high availability guarantees.
• Organisations requiring geographically safe, disaster-resilient operations via the reinforced bunker architecture and robust power/cooling infrastructure.
