Slow DNS lookups going via Singapore and Hong Kong

Hi,

I've been a user of NextDNS without issues for 2 years and been very happy with the service until now.

DNS lookups are very slow now.

For some reason my router (pfsense) is sending queries to singapore and hong kong yet I live close to Sydney.
I have not changed anything on my home network or client devices.

I ran the network and latency diag tool with output posted to:

Any ideas on what else to troubleshoot?
