I wasn't aware of Quad9, it seems like a pretty great option for those that are easy targets of scams/phishing.

Quad9 is supported/funded by City Of London Police, the same police that cooperates with ad companies to track people online. https://www.theguardian.com/media-network/media-network-blog... Keep away from this.

Quad9 is a consortium of 3 founding companies, none of which is the London Police Department. Additionally nowhere in your link is either Quad9, IBM, PCH or GCA mentioned. Please stop spreading and disinformation and FUD. See:

Earlier quoted context omitted.

While I whole-heartedly agree with your objection, I question the solution. How do you get high accuracy timing of DNS resolution in JavaScript inside the browser?

Using the Resource Timing API: https://www.w3.org/TR/resource-timing/#dom-performanceresour... This allows you to get accurate timings for every resource the page loaded, including the timeline of DNS request/response for that resource.

Yes, but how do you test different DNS providers? ;)

I think we'll start seeing the standard configuration of 1.1.1.1,8.8.8.8 everywhere. Google/Cloudflare tackled the UX of free DNS spectacularly with these gold IP addresses. It's the primary reason I use them instead of OpenDNS, which was an earlier player in this space.

Be careful with that, Google DNS (as an example) will start ignoring your DNS requests if you go over the rate-limit. Not an issue for home users, but an issue for any sizeable business.

I have run into this in the wild.

Presented as a weird, intermittent, "hey the internet is out" at the office around the same time each afternoon.

Which ISPs are so bad that you want to use external services, which are further in distance than your ISP, for speed? When I test with my ISP, they beat all of these services (both IPv4 and IPv6). They're simply closer to me in terms of hops. My router is another story though. The Fritzbox (>200eur router) adds 6ms of latency, and that's what is advertised over DHCP. (Might still be fine, since cached queries are fas…

NXDOMAIN hijacking is enough for me to switch, and most ISPs are doing it nowadays.

That’s quite a bold claim. Got any data to back it up?

Source: I've yet to see this on any ISP I've used anywhere, sans free airport wifis. Travelled pretty much every continent on earth.

Is there a tutorial on setting up your own? I've got a huge hosts file and would like it to affect all the devices at my home but setting up a DNS server always seemed high-level black magic to me.

You'd have to change your nameserver manually unfortunately.

But you could build a good webpage that actually measures how well your current nameserver performs over a wide variety of different types of lookups, both warm and cold caches etc.

My isp got the brilliant idea of rolling their own YouTube cache servers. It's great in theory but in or active they're under powered and so at peak hours I can't even stream 240p on my 500mbits connection. I've had to block their cache servers in my firewall for YouTube to be butter smooth at 1080p consistently. Another example is bell Canada who used to mine your DNS queries to profile you for ads, or ISPs that hig…

The YouTube cache is probably there not to increase performance for you, but to reduce ISP cost (ISP pays for all data received from outside of their network)
