iCloud Private Relay: information for Cloudflare customers

Apple's new Internet privacy service, iCloud Private Relay, allows users with iOS 15, iPadOS 15, or macOS Monterey on their devices and an iCloud+ subscription to browse the web more securely and privately. The system uses modern encryption and transport mechanisms to relay traffic from user devices through Apple and partner infrastructure before sending it to the destination website. Cloudflare is proud to work with Apple as a partner in this initiative, operating portions of Private Relay's infrastructure. Website operators can ensure the best possible experience for end users using iCloud Private Relay by keeping their geolocation databases up-to-date and ensuring that any systems relying on IP address as a signal or way of indexing users properly accommodate many users originating from one or a handful of addresses. Cloudflare's products, including its network, 1.1.1.1, Cloudflare Workers, and software like quiche, are well-suited to support Private Relay.
