Kolo NL4 Amsterdam

Kolo NL4 offers scalable colocation in one of Europe’s most connected metros. Located just 5 km from Schiphol Airport, this fully modernized facility delivers dense carrier access, reliable infrastructure, and always-on control in a flexible, secure environment.

Location

Capronilaan 2, 1119 NR Schiphol-Rijk

Kolo NL4 is located just outside Amsterdam, 5 km from Schiphol Airport and the nearest train station. This makes it ideal for enterprises needing proximity to major transit routes and interconnection hubs.

Why NL4?

NL4 is purpose-built for connected deployments that depend on uptime, interconnection, and metro proximity. With direct access to AMS-IX and NL-IX, N+1 and 2N power resilience, and efficient cold-aisle cooling, it’s a strong foundation for network-dense and high-performance workloads.

Built for metro performance

NL4 sits just outside central Amsterdam, giving you low-latency access to one of Europe’s top digital hubs. With direct routes to AMS-IX, NL-IX, and dozens of carriers, it’s an ideal launchpad for content platforms, SaaS, or any workload that depends on fast, redundant connectivity.

Designed for uptime

The facility is built to Tier 3 design principles with both N+1 and 2N power options at the cabinet level. With 4.7 MW of onsite capacity and an independent power grid from other Kolo NL locations, NL4 keeps your infrastructure running, even when others don’t.

Scalable to your needs

Whether you’re deploying a few cabinets or scaling across modular rooms, NL4 gives you options. Full 46U cabinets, private alleys, and protection zone layouts make it easy to grow securely, without compromising density or flexibility.

Cold and efficient

Cold-aisle containment and N+1 cooling redundancy ensure stable temperatures and optimal energy use, even at high loads.

Operational visibility

You stay in control with 24/7 access via personal card and fingerprint, plus continuous monitoring through our building management system. The site also includes workspace, meeting areas, and secure loading zones, because real-world operations need more than just power and ping.
