DE-CIX: one of the largest Internet Exchanges worldwide

DE CIX Internet Exchange

DE-CIX (Deutscher Commercial Internet Exchange) is one of the Internet Exchange Points that carries more traffic worldwide. Currently, it operates neutral interconnection platforms in Europe, the Middle East, North America and Asia. Stackscale is connected to DE-CIX with a clear objective: improving our connection routes to all the providers that exchange traffic there.

In addition to the Deutscher Commercial Internet Exchange, we are present in other IXPs such as AMS-IX and we are interconnected to diverse Tier 1 operators and a great number of companies through private peering agreements.

DE-CIX Infrastructure and interconnection

The mission of DE-CIX is to make interconnection easy anywhere. It was established in the 1990s in Frankfurt, Germany, and began its international expansion in 2014. In Madrid — one of Stackscale’s data center locations —, the IXP has hardware in the following data centers: Equinix, Interxion, Global Switch and GTT.

Its current infrastructure includes 25 IXP locations, accessible from thousands of data centers worldwide. In data centers where DE-CIX does not have its own hardware, they rely on partners to get customers connected.

DE-CIX Apollon platform

The Apollon platform is an Ethernet-based interconnection platform. It was built to manage the constant growth in customers and data traffic, and it is completely redundant. It is used at all DE-CIX IXPs, except for Berlin, Moscow, Saint Petersburg and the IXPs in India.

Traffic in Frankfurt

DE-CIX manages more than 10 Terabits per second in Frankfurt. Besides, in April 2022, it reached a traffic peak of 11.97 Tbit/s.

DE-CIX history and evolution

DE-CIX was founded in 1995 in Frankfurt, Germany. In 2020, it celebrated its 25th anniversary and it continues to grow worldwide. It started in an old post office, interconnecting 3 ISPs — MAZ (Hamburg), EUnet (Dortmund) and XLink (Karlsruhe). However, their founders quickly realized its potential and in 1998 they already moved the first switch to the Interxion data center.

Its growth in traffic has been amazing. It went from a peak traffic of 40 MBit/s in 1995 to 49 GBit/s in 2005 and 5.1 TBit/s in 2015. In December 2019, they set a new world record: 8,1 TBit/s. Currently, apart from its interconnection platforms in Germany, DE-CIX operates in many cities around the world: New York, Chicago, Madrid, Lisbon, Istanbul and Singapore, among others.

To celebrate its 25th anniversary, the IXP created a microsite about its 25 years of interconnection where you can find a lot of interesting data and content.
