Cloudflare DNS contact?

We're getting reports of users trying to log in or request 2FA emails from
Cloudflare sites (ex: California DMV) but seeing   errors that our well.com
domain isn't recognized as valid.  Well.com  has been around since 1993 and
our primary DNS hasn't changed since perhaps 2012. . Excerpts appended for
reference.

I strongly suspect these errors are related to a Cloudflare security check
for valid email domains. Hoping someone here can validate or disprove
this.  If it's a Cloudflare issue, any contacts here?

When I poke at an open cloudflare DNS server and  look up the A for well.com
I get a disturbing error: :
         server can't find well.com.well.sf.ca.us:

well.sf.ca.us is an antique  (but valid) A  record in  the sf.ca.us zone
and has no business appearing here.  Did something drop a period or  CRLF
on a list somewhere?

When I query AWS and Google DNS servers,  our DNS  looks correct and
unchanged
Thank you very much for any pointers!

Betsy
