Reasoning: I recall answering something similar regarding another Cloudflare exercise, and it was related to Cloudflare Proxy. It could also be related to the closest datacentre with the highest availability. I will stick with Cloudflare proxy for this one since I don’t have the user settings to investigate.
Answer:
Hello,
Please allow me to clarify your doubts.
I can see that you’ve enabled Cloudflare proxy, this means that from now on, your website will resolve to a Cloudflare’s owned IP and not yours directly. So, when someone tries to access your website, the request will go to one of Cloudflare’s servers and then routed to where the website is hosted.
This is why you are seeing the website being delivered from California.
I hope my answer helps you understand the behaviour behind your query. Please do let me know if you have any further questions.
