Hi all,

as we know the Azure Front Door is a Global service with many POPs (https://learn.microsoft.com/en-us/azure/frontdoor/edge-locations-by-region) and because of that I have some additional questions on which I could not find the answers on the Internet

QUESTION 1

Is it possible to configure the routing, that specific clients (base on some factors like geo-location) will be routed only to the POPs from the specific regions?

example:

  • Users from Europe will be routed only via POPs from EU
  • Users from Europe could use only POPs from EU, North America

explanations:

  • "users from Europe" means users which use public IPs from Europe

why: e.g. clients from Europe could see in their "traceroute", IP from Asia or US and ask to not send their traffic via this locations

QUESTION 2

Based on what information, the clients are routed to the specific POPs (latency, geo-location, availability)? ... and Is this configurable?

ps. Obviously I'm not assking about traffic between Azure FrontDoor POPs <-> origin/backends (https://learn.microsoft.com/en-us/azure/frontdoor/routing-methods)

I will be grateful for your help.

    Hi @Bart Olejnik A short answer to your questions is that it is not configurable. In Azure Front Door, requests from end users always reach the closest Front Door edge locations with Anycast.

    You can find more information at this link.
