trusted networks

We won't let you down!

The NIX.CZ Association is a neutral hardware platform for interconnection of networks. It also serves as a forum for sharing experience between the companies involved. NIX.CZ is the largest IXP (Internet Exchange Point) in the Czech Republic and ranks among the TOP 10 largest IXPs in Europe. Currently there are 140 networks with unique AS numbers connected. You can find out more at NIX.CZ site.



The FENIX project was created by the Czech peering node NIX.CZ and is primarily a reaction to intense DoS attacks targeting Czech internet services, media, banks and operators which occurred in March 2013. The purpose of the project is to ensure the uninterrupted of Internet services for connected entities during DoS attacks.


The members of the FENIX project manage themselves and are independent of the NIX.CZ Association and have complete decision-making autonomy. The project is designed for companies that provide important services and connections to these entities in order to secure their operation even in the most critical situations.
