Resolution Failure on macys.com when using 1.1.1.1 DNS

I was trying to visit macys.com today and the site seemed to be loading slowly and it ultimately ended up loading as follows:

Capture

As you can see in the console, the site is unable to load properly due to name resolution failures.

I tried this on my Mac and my PC (both running 1.1.1.1), and the issue occurs on both. Changing my IPv4 and IPv6 DNS servers back to automatic (removing 1.1.1.1) resolved these issues.

Diagnostic output from console:

If DNSViz is correct, all but one of macysassets.com's nameservers are returning SERVFAIL errors. (And the good one doesn’t respond to TCP!)

Using Quad9, I can resolve the subdomains, but not quickly or reliably.

I just tried accessing macys.com on my PC again and the issue seems to be resolved (huh puns!). It must have been a temporary issue.
