Kolo DC: DK4 Viby J.

DK4 Viby J. is a data center operated by Kolo and located at Søndervangs Alle 20, Viby J., Denmark, approximately 4 km from central Aarhus. Public market references describe it as an operational mission-critical colocation facility within Kolo’s Denmark platform, and Kolo itself lists DK4 Viby J. among its Danish data center locations.

From a location standpoint, Viby J. sits in the Aarhus metro area, one of Denmark’s main business and infrastructure hubs. Public descriptions position DK4 as suitable either as a primary high-density site or as a dedicated disaster recovery location, which aligns with Aarhus-area enterprise demand for resilient regional infrastructure and low-latency access across eastern Jutland.

🔐 Security & Compliance

1. I did not find a facility-specific public source for DK4 Viby J. that clearly verifies physical security controls such as CCTV, mantraps, badge access, fire suppression type, or named management-system certifications.
2. Kolo publicly presents its broader platform as secure colocation infrastructure, but I am not attributing platform-level security language as a site-specific DK4 claim without a dedicated technical facility page.

🌐 Connectivity & Carrier Access

1. DK4 Viby J. is positioned within the Aarhus metro area, supporting low-latency regional access in eastern Jutland. This is a location-based inference from the published address and distance to Aarhus city center.

3. I did not find a facility-specific public carrier list, cross-connect specification, cloud on-ramp reference, or explicit carrier-neutral statement for DK4 Viby J., so those are not included.
