When setting up a private link in Front Door you need to select a region. The list of regions is fairly limited and my country only has 1 region available. Looking at the docs it says that the private link feature is region agnostic but you should select the closest region. Secure your Origin with Private Link in Azure Front Door Premium.
I'm setting up a primary region and a fail-over secondary region where the primary region is an available option but the secondary region is not. In the event of a region outage in the primary region, I would like clarification of the effect on the secondary private link if it is also set to the primary region while the origin is in another region.
The next closet region to my secondary for the PLS has a much higher latency so prefer to select the lowest possible.
@Kurt ,
Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I shall check this internally and get back to you shortly

@Kurt ,
I received an update from the Product Team.
If the region of the Private Link goes down, the origin would be marked unhealthy and origin won’t get any traffic. For fault tolerance you can have multiple origins in an origin group with different privatelink locations. This way if one region goes down the request would be routed through different origin which is healthy.
So, for DR scenarios, consider deploying the secondary private link in a different region rather than that of primary private link
Please let us know if we can be of any further assistance here.
Thanks,

Thanks, that is what I expected. That would be a good note to have in the docs.
