Cloudflare Launches Custom Regions for Data Control

🔑 Enhanced Key Takeaways

• •New predefined regions added to Regional Services include Austria, Brazil, Cloudflare Green Energy, Exclusive of Hong Kong, France, Germany, India, and many others to address customer requests for specific areas[1][3].
• •Regional Services forwards encrypted TCP streams from out-of-region data centers to the nearest in-region data center via BGP routing, where Layer 7 products like CDN, WAF, Bot Management, and Workers are then applied[1].
• •Regions are defined using 2-letter ISO-3166-1 alpha-2 country codes, with U.S. and Canada supporting ISO-3166-2 subdivision codes; predefined regions include ENAM, WEU, SEAS, SAS, and others[2].
• •Support varies by product: Regional Services is available across most regions, while Geo Key Manager and Customer Metadata Boundary have limited support, e.g., full EU support but not Brazil[3].

🛠️ Technical Deep Dive

• •Cloudflare data centers advertise identical IP addresses via BGP; the closest network-wise data center handles initial traffic[1].
• •With Regional Services enabled, out-of-region data centers forward raw encrypted TCP streams without decryption to an in-region data center[1].
• •In-region data centers decrypt traffic and apply Layer 7 services (CDN, WAF, Bot Management, Workers); responses retrace the path back[1].
• •Region Mapping API uses ISO-3166-1 alpha-2 codes for countries and ISO-3166-2 for U.S./Canada subdivisions to identify regions[2].
• •Available regions include 20+ predefined options like Australia, EU, India, US states (CA, FL, TX), with varying product support[3].
