Best DNS to use in South Africa

This question is for any Roon customers in South Africa.

I’m having the “tidal loading slowly….” problem and skipping Tidal songs to songs in my local library. I am using ISP Afrihost and default to their DNS. Connection is fibre with 500 mbps down 240 mbps up.

I have tried the Cloudfare 1.1.1.1 DNS supposedly the fastest in the world but it is extremely slow. Perhaps there are other settings I need to change. Does anyone have advice for a good alternative to the ISP default DNS in South Africa? I’m currently based in Johannesburg but this will change to Cape Town permanently in October.

I would greatly appreciate some advice specific to this country.
