So I discovered a feature in my Edge Router feature I have been trialing over the last couple of days and it really has speed up the response times noticeably.

The option is service dns forwarding force-public-dns-boost

DNS resolution speed by forwarding all DNS request to multiple fast public DNS servers simultaneously (1.1.1.1, 8.8.8.8 and 9.9.9.9), then fastest response will be redirected to clients in LAN

Only problem is it seems to be hard coded Ubiquiti seems to think you can set up your own by manually configure the Dnsmasq all-servers option and use your own custom DNS servers.

forum post here: https://community.ui.com/questions/service-dns-forwarding-force-public-dns-boost-v2-0-7/793fd94f-8747-4dc2-b360-d9d61d52ac7b

wondering if anyone knew how to do it or can post a guide?

Works great till your using a service that still depends on dns to route you to the right local cache...

If speed is the goal I really don't understated using 3rd party DNS servers when the one provided by the RSP will be the fastest in literally 99% of cases.

99% might be a little high....

after some research I have managed to find out how to do via gui see screen shot below, all you need to do is at all-servers option.

This works well also when using ISP primary and secondary dns servers
