What Nix.cz, Z.s.p.o. does

NIX.CZ, z.s.p.o. operates the Czech Neutral Internet Exchange, a member-owned non-profit association (zájmové sdružení právnických osob) founded in 1996 in Prague that provides neutral peering infrastructure for internet traffic exchange. The platform connects 219 networks with 94% utilizing its route servers and carries 620.3 Gbps of traffic against 25 Tbps of provisioned capacity, with a historical peak of 3.7 Tbps. Customers span hyperscalers (Akamai, AWS, Google, Microsoft, Meta, Cloudflare), telecommunications operators (T-Mobile, O2, Vodafone, Slovak Telekom, CETIN), research and education networks (CESNET, CZ.NIC), government (Ministry of Defence), gaming platforms (Valve, Riot Games), and financial institutions (Komerční banka).

The platform is built on a modern leaf-spine topology using VxLAN EVPN on Cisco Nexus 9300 switches, supporting 100GE and 400GE port speeds. The infrastructure spans multiple data centers in Prague (NIX1/NIX2/NIX4/NIX5), Bratislava (NIX.SK1/2/3), Vienna (NIX.VIE1 at Digital Realty) and Frankfurt (NIXFRA2, NIXFRA5), with operations also conducted through the NIX.SK organizational branch in Slovakia. Core product offerings include peering services, route servers (AS47200, AS47627), the FENIX peering platform, DDoS protection (AS65253), remote peering through seven channel partners, and member portal/extranet tooling. NIX.CZ developed and open-sourced the Bird Spy network-monitoring tool.

Revenue is generated from recurring monthly port and membership fees, with pricing tiers determined by port capacity (10GE and higher). In 2020 the organization reduced port connection fees by approximately 20% and offered free new ports for two months during the COVID-19 pandemic, signaling a volume-driven commercial strategy. The organization does not publicly disclose financials, is governed by a five-member Board and three-member Supervisory Board, and is represented at the European Internet Exchange Association (EURO-IX) through Director Adam Golecký and Chairman Ondřej Filip, the latter serving as EURO-IX Board Chairman since November 2020.
