DE-CIX regional updates 2021

DE-CIX’s Annual Report 2021 was published last month and you can download it here. For a quick read through, here is a recap of regional updates.


In Germany, the historical home turf of DE-CIX, connected networks at our largest Internet Exchange DE-CIX Frankfurt amounted to close to 1100, while connected capacity rose by 12 percent. This was partly driven by the growing demand for 100GE ports and the first connected and operating 400GE ports. To meet the demand for higher bandwidth, we upgraded our edge routers in Frankfurt, leveraging the latest Nokia technologies and future-proofing the platform for the 800GE era.

The exchanges in Hamburg, Dusseldorf, and Munich benefitted from the demand for interconnection to occur closer to the edge. For example, in Hamburg, customer bandwidth increased by 40 percent and peak traffic 70 percent. In Dusseldorf, the increases were 162 percent and 65 percent respectively. To help to meet the regional demand, Ruhr-CIX became ready for service in February 2021, and we announced a partnership with Stuttgart-IX enabling local Internet service providers and enterprises access the DE-CIX Cloud Exchange. 


DE-CIX India’s Internet Exchanges in Mumbai, Delhi, Kolkata, and Chennai enjoyed accumulated growth in connected networks of over 60 percent, rising to 479 in total, with 100GE ports nearly tripling across locations. The overall connected customer capacity increased by almost 160 percent to almost 7 Terabits. DE-CIX Mumbai, the largest Internet Exchange in the entire APAC region according to PeeringDB, experienced peak traffic on the verge of reaching the 1 Tbps mark at year’s end, with almost 40 percent growth in connected networks.


In its sixth year of operations, DE-CIX Istanbul has grown to be an important interconnection gateway between the Middle East and Europe. In 2021, demand for greater capacity manifested in the increase of close to 170 percent in 100GE ports and more than 90 percent in connected customer bandwidth, which grew to over 2 Terabits.

Middle East

The UAE-IX in Dubai (UAE) continues to be the leading carrier and data center neutral Internet Exchange in the GCC. The number of 100GE ports grew by 50 percent, resulting in accumulated connected customer capacity of close to 2 Terabits, an increase of almost 40 percent.


In November 2021, we announced our expansion to the Nordics, with new DE-CIX platforms to be established in Norway, Denmark, and Finland. This expansion will serve the regional connectivity needs, boosted by new transatlantic and intercontinental submarine cables bridging the Nordics with North America and Asia.

North America

DE-CIX North America continues to be the largest carrier and data center neutral interconnection ecosystem on the North American continent. DE-CIX New York reached more than 260 connected networks during the year and exceeded 1 Tbps in peak traffic for the first time in December 2021.

Peak traffic at DE-CIX Dallas also jumped by over 50 percent to exceed the 300 Gbps mark and connected networks experienced growth of close to 25 percent, rising to 118 by the end of the year. DE-CIX Chicago, which celebrated one year in operation in late 2021, and DE-CIX Richmond, which went into operation in December 2021, together brought close to 50 further networks online in the North American ecosystem.

Southeast Asia

The DE-CIX Asia platform, a first-of-its-kind distributed Internet Exchange in Southeast Asia, has a footprint covering Singapore, the Johor Bahru and Kuala Lumpur metropolitan markets, and the new DE-CIX as a Service location in Brunei, Borneo-IX, established in 2021. Over 50 networks from across the region were connected to the DE-CIX Asia platform in 2021.

Southern Europe

For the Southern European region, accumulated connected capacity rose by close to 40 percent to 6.5 Tbits, and the number of connected networks by 17 percent to 450. DE-CIX Madrid, the heart of the largest neutral interconnection ecosystem in Southern Europe, celebrated its 5th birthday with growth of 23 percent in connected capacity and an increase to 225 connected networks. Another highlight of the year was DE-CIX Barcelona, which became ready for service in early October 2021, with three premium-enabled sites and 30+ networks already connected on day 1.
