2. Why is my site coming from California?!

Response

Hi, José Miguel here from Cloudflare Support — thanks for reaching out! Cloudflare routes traffic based on speed and availability, not just geographic distance. So while you're in London, routing through California can happen temporarily depending on network conditions. This is expected and helps ensure your site stays fast and stable.

Thought Process

CDN Routing Behavior

Cloudflare uses latency-based routing, not always physical proximity.
Factors like congestion, availability, or upstream provider issues can shift traffic.

How to Identify the Routing

You can check which Cloudflare data center responded using the CF-Ray header:

curl -I https://yourdomain.com

HTTP/2 200 
...
CF-Ray: 1234567890abcdef-LHR

The last part (like LHR above) shows the responding data center — LHR is London, for example.
