The way I handle this is to run unbound on a server in the public cloud and then tunnel over TLS from my local unbound to the cloud instance. My local clients query a PiHole, which forwards to unbound on localhost:15353, which forwards everything over TLS to the fully recursive instance of unbound in the cloud, which uses root.hints.

Still, your cloud vendor can see the requests.

But someone can see it, but you can rotate upstream resolvers to split requests if you have to.

How is the latency for such a setup? And how is the general browsing experience with said latency (I realize it also depends on which sites you frequently access)? I see some cloud providers/CDNs using a caching TTL as low as five minutes.

You spend most of the time waiting for the actual resolve to complete, not for the "transfer" time between you and VPS.

Source: I'm running Unbound on my notebook, I'm actually queried the stats for some heated discussion on reddit.

For example my current stats_noreset:

    histogram.000000.000512.to.000000.001024=17
    histogram.000000.001024.to.000000.002048=33
    histogram.000000.002048.to.000000.004096=251
    histogram.000000.004096.to.000000.008192=509
    histogram.000000.008192.to.000000.016384=1161
    histogram.000000.016384.to.000000.032768=1891
    histogram.000000.032768.to.000000.065536=2611
    histogram.000000.065536.to.000000.131072=3197
    histogram.000000.131072.to.000000.262144=2502
    histogram.000000.262144.to.000000.524288=1547
    histogram.000000.524288.to.000001.000000=857
    histogram.000001.000000.to.000002.000000=121
    histogram.000002.000000.to.000004.000000=70
    histogram.000004.000000.to.000008.000000=22
    histogram.000008.000000.to.000016.000000=441
    histogram.000016.000000.to.000032.000000=80

As you can see most of queries are completed in a way below 500ms. Adding another 20-40ms on top that doesn't change anything, because caching is a thing and with Unbound you can even ask to actually refresh the expiring records, so you would be served a fresh one from the cache every time, though I never bothered with it, it works fine even without it.
