A data centre that actually sits in the province.
Search for colocation in South Holland and you mostly find aggregators and providers whose data centre sits just outside the province — sometimes even in North Brabant. Our answer is concrete: Greenhouse in Naaldwijk, in the Westland. Rotterdam is about a 25-minute drive, The Hague 20 — Delft, Zoetermeer and the Westland are closer still.
Naaldwijk is no accidental data centre location. Greenhouse horticulture gave the Westland a robust power infrastructure, and Greenhouse reports sourcing 100% Dutch wind power with a certificate of origin; the newest building (DC3, opened in 2025) achieves a PUE of 1.15. The building is Tier 3 with N+2 redundancy and carrier-neutral — and since October 2021 there has been an AMS-IX PoP inside the data centre itself.
Rack space with the connectivity to match.
Colocation in Naaldwijk suits organisations that:
- Are based anywhere in South Holland and want their hardware housed professionally
- Want AMS-IX peering without renting a rack in Amsterdam
- Want their data centre within a half-hour drive
- Are after remote hands and management, not just rack space
Frequently asked questions about colocation in South Holland.
Where in South Holland is the data centre exactly?
In Naaldwijk, municipality of Westland, right between Rotterdam and The Hague. Your hardware sits within the province itself — not in Amsterdam or North Brabant with a South Holland label on it.
What makes Naaldwijk a logical location?
Thanks to greenhouse horticulture, the Westland has a robust power infrastructure, and the data centre runs on Dutch wind power; the newest building (DC3, 2025) achieves a PUE of 1.15. Add the central position between Rotterdam and The Hague and the location works practically and sustainably.
How quickly can I reach my hardware?
From Rotterdam it's about a 25-minute drive, from The Hague 20 — and less from Delft, Zoetermeer or the Westland. Access is 24/7, with mandatory ID and advance registration — done in five minutes. For small jobs you don't drive at all: remote hands is included.
What connectivity is available?
The data centre is carrier-neutral and hosts an AMS-IX PoP since October 2021 — together with Rotterdam the first AMS-IX expansion outside the Amsterdam metro. You also connect to our network (AS211588) for IP transit: dual-stack, BGP and your own IP space from a /24 or /48 if you wish.
Can I fail over to a second site?
Yes. We also deliver colocation in Ede — a different power grid, linked via our own network. Replication or failover between the two never crosses the public internet, with one provider for both sites.
Your hardware doesn't have to leave the province.
