Cloudflare One boosts proxy mode performance with QUIC
🚀 Cloudflare rebuilt the Cloudflare One Client’s proxy mode to use QUIC streams and HTTP/3 CONNECT, removing the prior L4→L3 translation via smoltcp and deprecating WireGuard for proxy mode. The change keeps traffic at Layer 4, enabling native congestion and flow control, transport tunability, and substantially better throughput and latency in internal tests. Administrators should upgrade to minimum client version 2025.8.779.0 and enable MASQUE local proxy mode to benefit from these gains.
