Hey Constantine,

John came in with a technical issue. If you have nothing worthy to say about it specifically, it's best to keep quiet.

Thanks!

I don't understand why anyone, especially anyone frequenting NANOG, would use Cloudflare for their DNS.

Cloudflare runs a racket business, and their whole business model depends on them being a monopoly; plus people buying into the vapourware that they offer.  When have monopolies been good for any industry?  There's plenty of evidence of Cloudflare 1.1.1.1 not working correctly; I'm sure one of their employees (or the CTO!) will show up shortly to say otherwise!

FULL DISCLOSURE: this is an end-user issue, but one that might have some
operational relevance, particularly if anyone from Cloudflare DNS is on
the list

EXECUTIVE SUMMARY: twice in six weeks Cloudflare DNS on my new Netgear
Orbi cable modem/mesh WiFi hotspot has completely lost track of one (and
only one that I know of) prominent US domain: usbank dot com

Internet provider: Comcast/Xfinity "Extreme Pro+"

Dynamic IP address via Comcast that hasn't changed in six-seven years

New Netgear Orbi cable modem, configured with DNS through Cloudflare
(1.1.1.1 and 1.0.0.1)

Again, twice in 6 weeks Cloudflare DNS seems to loose complete track of
usbank dot com as a domain

Symptoms: Firefox on Ubuntu Linux returns that little puzzled dinosaur
cartoon thing and "We can't seem to find this website right now"

BUT ALSO:

Each one of ping, traceroute, dig and host returns

Host usbank . com not found: 2(SERVFAIL)

or some variant thereof

Everything else works "just fine" as the saying goes

And the Cloudflare DNS drop lasted for days the first time around

I can switch over to Google DNS (8.8.8.8 and 8.4.4.8) in the Orbi and
immediately fix the problem

So. Seems odd that Cloudflare DNS would apparently loose complete track
of a major US domain name like usbank dot com

Or am I missing something?
