Can't resolve canadacentral.cloudapp.azure.com

nslookup -type=soa canadacentral.cloudapp.azure.com 1.1.1.1
Server:  one.one.one.one
Address:  1.1.1.1

*** No start of authority (SOA) records available for canadacentral.cloudapp.azure.com

whereas Google can do it:

nslookup -type=soa canadacentral.cloudapp.azure.com 8.8.8.8
Server:  dns.google
Address:  8.8.8.8

Non-authoritative answer:
canadacentral.cloudapp.azure.com
        primary name server = prd1.azuredns-cloud.net
        responsible mail addr = msnhst.microsoft.com
        serial  = 10001
        refresh = 900 (15 mins)
        retry   = 300 (5 mins)
        expire  = 604800 (7 days)
        default TTL = 60 (1 min)

Records under that domain won't resolve either; they get:

No internal type for both IPv4 and IPv6 Addresses (A+AAAA) records available

Is that supposed to be set up as domain and not as regular record?

Actually, for me it does resolve via Cloudflare.

To which datacentre are you connecting?

Works for me…

[~] dig soa canadacentral.cloudapp.azure.com @1.1.1.1 +short
prd1.azuredns-cloud.net. msnhst.microsoft.com. 10001 900 300 604800 60

Not sure what records are supposed to exist under that zone so can’t verify that individual record lookups occur. See also: Have problems with 1.1.1.1? *Read Me First*

YYZ does seem to have some issues, but these were mostly DoH related AFAIK.
