Who Runs the Internet?

DKIX, founded three decades ago in Frankfurt, has grown into one of the world’s largest internet exchange operators. Today it runs platforms in 60 metropolitan areas across six continents, connecting more than 4,000 networks in hundreds of data centres. Its distributed architecture means a single metro is served by multiple facilities, allowing members to see every other participant through a simple VLAN activation. This scale turns the exchange into a global interconnection hub where traffic can jump from New York to Istanbul without leaving the DKIX fabric, dramatically reducing latency and transit costs.

The rise of artificial‑intelligence workloads is reshaping peering requirements. Customers now request 400 Gbps ports to feed massive model training and inference pipelines, far beyond the traditional 10 Gbps peering slots. DKIX responds with AI‑focused exchange services, cloud‑on‑ramps, and even exploratory space‑based connectivity for low‑Earth‑orbit satellites. These offerings address not only raw bandwidth but also the security and latency sensitivities of machine‑to‑machine communication between autonomous agents. By aggregating diverse networks in one platform, the exchange can route AI traffic efficiently, providing the fast, secure pathways that emerging applications demand.

Local internet exchanges prove vital when regional infrastructure fails. During the recent Red Sea cable cut, traffic that normally traversed Frankfurt shifted to Middle‑East IXs, preserving service quality for operators that peered locally. This demonstrates how peering close to end‑users boosts resilience and cuts latency. Enterprise‑grade services, such as Microsoft’s Azure Peering Service hosted on DKIX, further expand the exchange’s relevance, offering secure, managed connectivity for midsize and large businesses. While carriers remain essential for last‑mile delivery, IXs act as enablers, fostering a symbiotic ecosystem that supports both wholesale and enterprise traffic growth.
