On the evening of 27 April 2021, total VIX traffic exceeded the "magic threshold" of 1 terabit per second (5-minute average) for the first time. We are delighted about the new traffic record!


The Vienna Internet eXchange has a new logo! If you use the VIX logo on your website or in printed matter, we ask you to integrate the new logo now. It is available in various formats at Media / Downloads.


From July 2019, some price reductions take effect at the VIX. Invoices for existing participants will be automatically adjusted. The fee for a 10G port is lowered to € 500 (from € 550), for a 100G port to € 2500 (from € 3500). All other prices and the 20% dual-site discount remain unchanged.


Since May 2019, a new root DNS server instance is represented at the VIX: The Verisign-operated J-Root server uses - like many other participants - the VIX route servers.

Newest VIX Participants

Peering Days

Peering Days is an international conference for Internet Service Providers, primarily from Central and Eastern Europe. However, participants (network engineers, peering coordinators, cloud administrators and data center operators) come from across the globe to get access to expert knowledge, make valuable contacts, and be part of a two-day, mind-blowing experience.


The Vienna Internet eXchange is a founding member of the European Internet Exchange Association (Euro-IX). Euro-IX was launched in May 2001 by Europe's leading Internet Exchange Points (IXPs). IXPs interconnect the networks of Internet Service Providers to enable them to easily and efficiently exchange their Internet traffic.
