Hi Miles, Below is the response whose header was provided earlier. Leif already identified the X-Cache header was from origin.

Is this hit from my ATS server or origin CDN? Because for several other objects i can see my ATS in the "Server:" header so does it means the object is cached where server header has our ATS/version? Unless you have enabled the xdebug.so plugin, and triggered it in the request, this is likely coming from the origin. Maybe a peering CDN?
