We encountered a strange DNS issue to access "nav-edge.smartscreen.microsoft.com".
From US,
nav-edge.smartscreen.microsoft.com has a cname to "prod-atm-wds-edge.trafficmanager.net", and "prod-atm-wds-edge.trafficmanager.net" has a cname to "prod*.northcentralus.cloudapp.azure.com" and "prod*.northcentralus.cloudapp.azure.com" returns a ip address.
But from AU&NZ,
nav-edge.smartscreen.microsoft.com has a cname to "prod-atm-wds-edge.trafficmanager.net", and "prod-atm-wds-edge.trafficmanager.net" has no cname to "*.cloudapp.azure.com". and it has no A record in tm1.dns-tm.com. So nothing is returned.
Could you please check if this is expected? How can it be fixed if it is a bug? Please let me know if I can help.
