This post details Cloudflare's global backbone infrastructure in 2024, highlighting a 500% increase in capacity since 2021. It explains the strategic importance of the backbone for traffic routing control and cost-effectiveness, detailing peering and IP transit methods. The post showcases how the backbone supports internal traffic (e.g., tiered caching, Magic Transit) and external traffic from public clouds. It emphasizes the network's expansion into regions with less developed infrastructure to combat traffic tromboning and improve localized data flow, supporting Data Localization Suite. Performance improvements, such as reduced latency between Lisbon and Johannesburg, are quantified with RTT measurements.
