CloudFlare and APNIC have launched a free DNS service @ 1.1.1.1 that claims to prevent your ISP from selling your data:

The claim to be the "fastest" comes with the caveat of "privacy-first" -- I wonder how it stacks up against DNS services that don't provide any inherent perceived privacy?
On a related note, the service is being hammered by multiple gbps of trash data:

Personally, I've used
Google's public DNS for years now, since it's always seemed to be more stable than my ISPs, but this CloudFlare option is really tempting. Handing over literally all of my browsing data to Google is probably not the best idea.
