DE-CIX

DE-CIX (Deutsche Commercial Internet Exchange) is an operator of carrier- and data-center-neutral Internet exchanges (IXs), with operations in Europe, North America, Africa, the Middle East, India and Southeast Asia. All DE-CIX activities and companies are brought together under the umbrella of the DE-CIX Group AG.

DE-CIX is accessible from data centers in over 600 cities worldwide and connects thousands of network operators (carriers), Internet service providers (ISPs), content providers, and corporate networks from more than 100 countries. In terms of data throughput, DE-CIX Frankfurt is one of the largest Internet exchanges in the world. All national and international DE-CIX activities and companies are consolidated under the umbrella of DE-CIX Group AG. DE-CIX employs nearly 250 people from around 35 countries worldwide.

The DE-CIX Internet exchange point (IXP) situated in Frankfurt, Germany, is the largest IXP worldwide in terms of peak traffic, with throughput of 17.09 terabits per second (Tbit/s) in April 2024. In addition to DE-CIX in Frankfurt, DE-CIX operates IXPs in approximately 40 locations around the globe, with three further IXs exchanging peak traffic in excess of 1 Tbit/s, these being DE-CIX New York, DE-CIX Madrid, and DE-CIX Mumbai, with DE-CIX Mumbai becoming the largest IXP in the Asia-Pacific according to PeeringDB in 2021.

DE-CIX operates Internet exchanges worldwide and offers its customers various interconnection services. Its core business is the provision of comprehensive peering options. Peering allows DE-CIX customers to use the company's data center and carrier-neutral infrastructure to set up comprehensive data exchange and traffic between their networks and the networks of other peering partners (also known as "peers") connected to DE-CIX for a monthly fee. Peering is an alternative to IP transit, where network operators route their data traffic through the network of a larger provider for a fee and on an individual basis depending on the destination. In addition to Internet exchanges specializing in peering, DE-CIX has also been operating Cloud Exchanges at many of its global locations since 2013, enabling DE-CIX customers to connect to over 50 cloud service providers.
