To improve latency and reduce costs for backhaul connectivity, three providers decided to establish an Internet Exchange in the back room of a postal office in Gutleutviertel in Frankfurt.

Hamburg-based MAZ, EUnet from Dortmund and XLink from Karlsruhe were the first to connect their networks in Frankfurt at DE-CIX.

DE-CIX was originally managed by Electronic Commerce Forum, now known as eco – Association of the Internet Industry.

DE-CIX extended its reach to additional data centers, introducing Force10 and Brocade switches and scaling the platform to over 700 10-Gigabit ports.

In 2019, DE-CIX was one of 3 IX operators to jointly develop the IX-API, which provides the basis for the automation of interconnection services over IXPs.

[23] In 2021, DE-CIX received a patent for its security service “Blackholing Advanced”, which enables innovative filtering mechanisms in the protection of networks against DDoS attacks.

[27] The IX operator experienced massive growth during the Covid-19 pandemic, regularly breaking traffic throughput records.

The DE-CIX node UAE-IX in Dubai must also "comply with the local legal regulations on the transfer of data.
