Concentration is rational.
Until it isn't.

Carriers build where the customers are, customers land where the carriers are — and everything piles up in one metro. The market won't correct itself, so we changed the economics: a full exchange core in The Hague, own dark fiber to every metro that matters, and 36 months free to peer south.

02 · The Core · DFDC THG1

One building holds
the center.

The LSIX core lives inside DFDC THG1 — our sister company's carrier-neutral facility in The Hague. Exchange and data center under one holding: no landlord, no waiting list, no cross-connect politics.

Priced like a utility.
Provisioned like software.

Every LSIX port is a programmable endpoint on the fabric. Peering is included, everything else is one order away — from the portal or the CLI. Month-to-month on list price, no setup fees, LAGs at no extra cost.

04The GroupONE HOLDING · THREE LAYERS

Facilities. Network. Exchange.

LSIX is part of the LayerSwitch group, next to Netrouting and DFDC. When the data center, the backbone and the exchange share one owner, provisioning takes minutes — not weeks of emails between three vendors.

DFDC
The Facilities

Carrier-neutral colocation in The Hague. 3.50 MW, distributed 2N+1 — and the physical home of the LSIX core.

Netrouting
The Network

Bare metal, cloud and the AS6206 backbone across 28 locations on three continents. The hands and the hardware.

LSIX
The Exchange

The neutral meeting point — where 103 networks, including those two, exchange traffic on equal terms.
