The 6th CEE Peering Days event

The 6th CEE Peering Days conference took place in Berlin last week. The conference traditionally welcomes the representatives of peering nodes, ISPs, and Datacenter providers. Over the years this conference has become a major event and one which is regularly attended by experts from around the world to share their experience and discuss potential cooperation with fellow attendees. The main organizers of the event were the neutral peering nodes: NIX.CZ, and, and the local partner of the conference was the Berlin-based BCIX.

Martin Semrád, CEO of NIX.CZ., said that:"Interest in the CEE Peering Days is growing across Europe and the Central European conference is becoming a pan-European event. A total of 214 participants attended this year’s event, thanks to which we also received support from the European Commission's Connecting Europe Facility (CEF). In addition to traditional topics related to routing and security, topics of regulatory issues - which IXPs must often address - in particular the implications of the NIS Directive discussed by Zuzana Duračinska from CSIRT.CZ, were included in the programme ".

Presentations by representatives of EURO-IX, RIPE NCC, Netflix or PeeringDB are already available on the conference website. Those who are interested may find a comprehensive report including photos at

NIX.CZ Association has a new Chairman of the Board

At today’s meeting, the Board of Directors of NIX.CZ, the neutral peering node for the Czech Republic, elected Ondřej Filip as the new Chairman. Filip will take up his position on 1 July, replacing Josef Chomyn, who has been appointed to the Czech Telecommunication Office Council two weeks ago. Ondřej Filip is not exactly a newcomer - he has been a member of the Association’s governing body since 2002. From the beginning of July, the Board of the Czech neutral node will therefore have four members: Ondřej Filip, Zbyněk Pospíchal, Jaroslav Střeštík and Milan Švácha.
Josef Chomyn has made an indelible mark on the Association. As a member of the Board of Directors and its Chairman, he has been a leading voice in our Association for more than 17 years. It is also thanks to him that today, NIX.CZ is one of the most important European interconnection hubs. Personally, I would like to wish Josef continued success in his work as a member of the Council of the Czech Telecommunication Office. It is a great honour to be taking over this position after him,“ said Ondřej Filip.
Ondřej Filip graduated from the Faculty of Mathematics and Physics of Charles University in Prague (Computer Science) and the University of Pittsburgh - Joseph M. Katz Graduate School of Business (MBA). During his studies at Charles University, he worked at IPEX, where he later became the Technical Director and Member of the Board. Since 2004, Ondřej Filip has been the Managing Director of CZ.NIC, a national domain administrator. In addition to performing his functions at CZ.NIC and NIX.CZ, he is also active on the boards of two key international organisations: Euro-IX (European Internet Exchange Association) and IX-F (Internet eXchange Federation). 

NIX.SK expands into a new data centre and connects Google

Starting from today, NIX.CZ Association, which runs one of the main internet exchange nodes in Slovakia (NIX.SK), is also offering its services from the DIGITALIS data centre in Bratislava. This also means that it can now provide a direct connection to all the existing customers of this data location. The first company to take advantage of this offer is Google. NIX.CZ now provides connection on both sides of the Danube, through two mutually independent data centres (SITEL and DIGITALIS).
“Thanks to the data connection from Google, Slovak users will now find it easier to access services such as YouTube or Gmail. In reality this will bring better and faster access to Google services,” said Martin Semrád, Director of NIX.CZ, which operates the Slovak peering node NIX.SK.
