The distribution of CDN, cloud and content provider capacity across Internet Exchanges (IXPs) provides a fascinating lens into the physical infrastructure of the Internet and public peering.
While hyperscalers and CDNs increasingly deploy private backbone infrastructure, public peering remains a critical mechanism for regional traffic distribution, cache efficiency, eyeball reach, and resilience.
This study aggregates the port capacity of ten of the most IXP-interconnected CDN, cloud and content networks and ranks IXPs by total capacity. This ranking provides insights into the choices made by the networks, on an individual basis but also collectively as a group of CDN, cloud and content providers with significant influence in the global interconnection ecosystem. The networks covered are Akamai, Meta, Amazon, Hurricane Electric, Cloudflare, Fastly, Microsoft, Google, Netskope and ACE CDN.
The limitations of this analysis are obvious: presence at exchanges could be incorrect or port capacity could be out of date, for instance. However, most of the networks under analysis depend heavily on PeeringDB automation. This gives the report a relatively high level of confidence.
