Google latency problem

Zero Trust 1.1.1.1
1

Hello there!
I have been having a little issue with the 1.1.1.1 DNS resolver.
The thing is that when resolving any Google linked website (google.com, gmail.com, youtube.com,…) the response IP I get points to a Google server really far away from me (I live in Slovakia and the IP is in Brazil) resulting in a high latency and slow loading times.
I don’t have this issue when using other DNS resolver (tried 8.8.8.8 and my ISP’s DNS) so I will switch to another DNS server until this issue persists.

Example when using 1.1.1.1 DNS (responds with server in Brazil with ~215ms latency)

C:\Users\simon>nslookup google.com
Server:  one.one.one.one
Address:  1.1.1.1

Thanks for adding the diagnostics info. We’ve identified the root cause, it is because our egress IP being used in the data center answers your DNS query is mis-labeled as in Brazil in same IP geo-location databases. We are working on getting it fixed.
