How I Avoided GCP → Cloudflare CDN Peering Charges Using IPv6 If you've been using Google Cloud Platform (GCP) with Cloudflare (CF), you've probably noticed something frustrating: Traffic sent from GCP to Cloudflare often does not count toward the standard free 200GB outbound quota . Instead, it gets categorized under the CDN peering billing tier , which can become surprisingly expensive. Even worse, the free direct connection can sometimes be painfully slow. After experimenting with different routing methods, I found a practical workaround that significantly improves speed while avoiding most CDN peering charges. In this post, I'll explain the setup, how it works, and a few limitations to keep in mind. The Core Idea The solution is based on routing traffic over IPv6 through Hurricane Electric (HE Tunnel) instead of relying entirely on standard IPv4 outbound routes. Current Routing Flow Inbound Traffic: User → Cloudflare → HE Tunnel → GCP Outbound...
