SITELiX Project replaced by NIX.SK: The Czech peering node enters the Slovak market

Bratislava/Prague, 18th March 2015 -- In early January, the Czech Republic’s neutral peering node NIX.CZ announced that it was taking over the running of the SITELiX project, one of the two peering nodes currently active in Slovakia. During today’s Peering Day conference in Bratislava, the Director of NIX.CZ Martin Semrád introduced several new initiatives connected with this move. They include expanding the offer for Slovak networks, a new name (NIX.SK) and the launch of the Route Server service, previously lacking on the Slovak market. All details are available on the website:

The NIX.SK Project (previously SITELiX) remains a neutral peering node dedicated to Slovakia and will not be interconnected with the Czech peering node. NIX.CZ Association will be running the node from Prague, while maintaining a separate organizational unit in Bratislava, mostly for tax-related and administrative reasons.

“Today marks the end of the SITELiX Project and the beginning of NIX.SK. The similarity of the name with NIX.CZ is no coincidence – we would like it to reflect the values and the vision we have been developing in the Czech Republic for more than 18 years. Another important news is the launch of our new Route Server service, which will facilitate creating peering connections for new member companies. We are also expanding the NIX.SK offer to include 100 Gb connections. No such high-capacity connection had previously been available in Slovakia,” said Martin Semrád, the Director of NIX.CZ Association, which runs the NIX.SK peering node.

The Slovakian interconnection market acquires a strong new partner with abundant experience in data transfer between Internet operators. NIX.CZ is also hoping to bring new international content providers to Slovakia, which are currently active in the Czech Republic and elsewhere, in order to improve their interconnections with Slovak networks.

More information about the NIX.SK Project is available on or in the press release announcing the expansion of NIX.CZ to the Slovak market published in January of this year, which can be found in the News section of the Association’s website.


In taking over the SITELiX project, the Czech peering node NIX.CZ enters the Slovak Internet connection market

Prague/Bratislava, 14th January 2015 – NIX.CZ Association, the Czech Republic‘s neutral IX node, is in the process of taking over the running of the SITELiX Project, one of Slovakia’s two peering nodes. This will give its members and customers the possibility to operate in a modern and expanding peering node in Slovakia, which will function on the same principle as the Czech NIX.CZ. At the same time, the Slovak Internet connection market will acquire a partner with vast experience in the field of inter-operator data transit. NIX.CZ will also try to bring to Slovakia other key international players already active in the Czech Republic in order to further develop the Slovakian market. The SITELiX project remains a separate and neutral peering node for Slovakia and will not be integrated into the Czech peering node.


Marián Okres, the project manager of SITEL, which had previously been running SITELiX, said: “By taking over the SITELiX project, NIX.CZ is giving SITEL, a Slovak company, the opportunity to fully concentrate on its key activities, which include running its own datacentres and building, operating and servicing optical networks. On the other hand, NIX.CZ Association is going to focus on running and developing one of Slovakia’s two peering nodes, which is good news above all for our customers. The Czech peering node is one of the most important in the field and is bringing years of experience and solid know-how of Internet interconnection into the project.”


An agreement between the representatives of SITEL and NIX.CZ was signed before the end of last year. At the moment, the project is being handed over, a process which should be completed in the following months. The SITELiX project will be managed from Prague, with the current and future customers of SITELiX becoming customers of NIX.CZ. According to the Association’s plan, in the future SITELiX should follow the same operating model and principles as the Czech peering node.


“I am very happy that we can offer our experience and projects to entities currently operating in Slovakia,” the Director of NIX.CZ Martin Semrád said. “Once the SITELiX project has been handed over, we will begin to develop and expand its infrastructure to match the standard offered by NIX.CZ in Prague. The openness, stability and transparency of the Slovak peering market, which are our priorities, are also important for the functioning of Czech companies active in the Internet field. Many of them are connected not only in the Czech Republic, but also in Slovakia. Some of these networks are our members and have previously expressed interest in getting the same standard of service they are used to in the Czech Republic from our Eastern neighbours.”  


More information and future growth strategies of the SITELiX project will be presented during the Peering Day conference that will take place in the Slovak capital in March 2015. The conference will bring together experts on Internet interconnection from Europe, Asia and America.
