Colocationix gmbh: ColocationIX DC1

ColocationIX DC1 is located at Wachtstraße 17-24 in Bremen (28195), Germany, and is operated by ColocationIX GmbH. The facility is built inside a former federal government nuclear shelter, giving it a uniquely robust structural foundation and positioning it as a very high-security colocation site in Northern Germany. 

Strategically, Bremen offers excellent connectivity to major Northern European network hubs and seaport infrastructure, making DC1 an attractive option for enterprises, network operators and critical infrastructure operators seeking low-latency access to maritime- and datacenter-centric ecosystems. The facility’s underground-shelter heritage gives it a distinctive market positioning in German and European colocation: a “data fortress” with both physical and digital strengths.
