I know this is not for everyone, but I strongly prefer to run my own recursive resolver at home. Performance is great, plus I get regular DNS for the machines on my home network. Also, it was a fun little project. :)
I like to share the cache of the DNS resolver with as many people as possible because that's what gives you the best performance. A local resolver just for me can't really do that.
Another option here is DNS servers that block ads. I can't vouch for the company itself, but I have found AdGuard DNS reliable and effective, if not memorable: 176.103.130.130, 176.103.130.131 https://adguard.com/en/adguard-dns/overview.html

There’s ping.sunet.se as maintained by the Swedish University Network (i.e. the network connecting Swedish Universities; there is no single “Swedish University”).
The advantage of pinging IPs is that you don’t have to have a working DNS setup to test your connection. If DNS does work, then your connection probably works, too.
Surprised that 4.2.2.x (Level3) is not on the list --- it's also unfiltered DNS, and run by a company that focuses only on networking.
So the author is a security expert who recommends two companies that are notorious for their security flaws (Norton, Cisco), two companies that track your DNS queries for profiling (Google, Cloudflare) and IBM... Yeah, this sounds totally legit...
> two companies that track your DNS queries for profiling (Google, Cloudflare) Can you elaborate? Neither Google nor CloudFlare seem to collect information for profiling.

Cloudflare does not store any information, but they are pretty frank about passing it on to APNIC for "research" as part of the deal where APNIC lend the 1.0.0.1 and 1.1.1.1 address to them. This is pretty well established and actually openly communicated by both entities, so should be easy to DDG. You are of course free to believe that this data is totally anonymized and not used for profiling / targeting at all, but imo that is pretty naive.
Resident evil. It has begun.

DNS servers should not be used as "internet connectivity tests" by pinging them. They are not maintained as ICMP test servers, and that is not their purpose. While many do not block ICMP packets, there are typically rate limiting systems in place, and other reasons why they would not respond to ping requests. Pinging DNS servers is a shitty inconclusive test for internet connectivity, or SLA measurements etc etc.
So, what should we ping for testing Internet connectivity ?

When we talk about aggregate data it's things like total number of queries made to 1.1.1.1, number made by AS, and geographic region. Its purpose is only to show us if people are using 1.1.1.1 and how that changes over time.
