To have more efficient traffic while being protected by Origin Shield, it is recommended to choose the location of your Origin Shield to be the one that is nearest to the origin server that hosts your target domain.
To set the location of your Origin Shield, navigate to ‘Origin Shield’ > 'Region'.
You need to set the target domain from the ‘ Operation level panel’.
First, click the ‘Setting’ (gear) button, to show all available Origin Shield locations.
Select the location of your Origin Shield. The Origin Shield at that location will be designated to protect your origin and will be deployed to all your CDNs.
Selecting "Auto" means the system will automatically detect the region closest to your origin server.
Finally, click the ‘Save’ button to set the Origin Shield location.
