What It Is

NSIX (North Sea Internet Exchange) is an open Internet Exchange Point (IXP) based in the Netherlands. To be clear, it is not a traditional CDN acceleration service, but a network peering platform designed to break down expensive traffic-exchange barriers through a community-driven model and reduce interconnection costs.

Core Analysis

• Service type: Its core offering is BGP peering over Layer 2 VLANs. It also provides a Marketplace where members can access partner services such as colocation and transport through a single cross-connect.
• Locations and coverage: Coverage is highly concentrated. It currently supports only three PoPs in Amsterdam: NIKHEF, NorthC Amsterdam, and Qupra DC.
• Billing and pricing: Pricing is based on port speed, rather than the traffic-based or 95th-percentile bandwidth billing commonly seen with CDNs. Its pricing is highly disruptive: 10G and 25G ports are completely free (you need to provide your own optics); 40G ports cost a one-time fee of €100 plus €29/month; 100G ports cost a one-time fee of €250 plus €49/month.
• DDoS protection and edge computing: No DDoS protection or edge computing features are mentioned. This is purely a network interconnection facility.
• China nodes / ICP filing: There are no China nodes, and ICP filing is not relevant.

Pros and Cons

Pros: No monthly fee for 10G/25G ports, making costs extremely low; open community model; no monthly cross-connect fee at some PoPs; no contractual lock-in, offering flexible access.
Cons: Extremely limited geographic coverage, with presence only in Amsterdam; high entry requirements—you must have your own ASN and at least a /24 IPv4 or /48 IPv6 block; operates on trust, with no formal contract or SLA guarantees; lacks add-on features such as security protection.

Who It’s For

Best suited to network operators, ISPs, or technically capable companies that already have equipment deployed in Amsterdam, own their own ASN and IP resources, and want to reduce Transit costs. It is not suitable for ordinary website acceleration needs.

Access from China

As a Europe-based local IXP, NSIX has no direct connectivity to mainland China. Access would require international Transit or a dedicated line, with no optimization for Chinese networks and no China-oriented payment support. Comparable alternatives include AMS-IX or NL-ix.
