> Performance? Due to DNS caching at the resolver level,
Not sure about the validity these arguments. Yes, Google is likely to have more cached data than you, but they can also be a half a country or two away.
In my experience caches matter less than one might think, since more popular data is usually the one that's low latency anyway.
> Privacy? With DNS over TLS/DNS over HTTPS, your ISPs can't see
Let's agree on one thing: That surf data is a lot more valuable to Google than most other actors, including your ISP, because they're the ones in a position to monetize it.
Your ISP has more data than they know what to do with anyway. Should they try to monetize it despite the murky legal waters (they really wouldn't want to knowingly help copyright infringement, for example), the realistic option would be for them to sell it to someone very much like Google. It should not come as a surprise that the latter is happy to shortcut the process.
>Yes, Google is likely to have more cached data than you, but they can also be a half a country or two away.
Google has edge nodes in pretty much every ISP of every country except China. A query to Google's public DNS never leaves your ISP, much less your country.
>When clients send queries to Google Public DNS, they are routed to the nearest location advertising the anycast address used (8.8.8.8, 8.8.4.4, or one of the IPv6 addresses in 2001:4860:4860::). The specific locations advertising these anycast addresses change due to network conditions and traffic load, and include nearly all of the Core data centers and Edge Points of Presence (PoPs) in the Google Edge Network.
