I'm not sure this will affect my latency here in Zurich. Quad9 is already impressive with a 2ms ping, which is surprisingly a bit faster than Google DNS and a few other major providers from my home.
We did just turn up a third Zurich location two weeks ago, in Equinix ZRH4, so our presence there is pretty robust; on par with New York, London, Singapore, San Jose, and Los Angeles.
