[dns-operations] Oddness with Cloudfare authoritative servers

[Brown, William]

We have a school district that is trying to resolve the domain deltamath.com.  This issue is impacting the classroom use of this service.

The authoritative servers are tani.ns.cloudflare.com and jarred.ns.cloudfare.com.  Tani seems to work correctly.  Jarred however, will return two different results:

Here are the results of four tries within a few seconds:

[wbrown at ns3 ~]$ dig @jarred.ns.cloudflare.com deltamath.com +short
172.67.75.10
104.26.2.229
104.26.3.229
[wbrown at ns3 ~]$ dig @jarred.ns.cloudflare.com deltamath.com +short
104.26.2.229
104.26.3.229
172.67.75.10
[wbrown at ns3 ~]$ dig @jarred.ns.cloudflare.com deltamath.com +short
172.67.75.10
104.26.3.229
104.26.2.229
[wbrown at ns3 ~]$ dig @jarred.ns.cloudflare.com deltamath.com +short
172.64.80.1

Is anyone from Cloudflare of the list that can assist with resolving this?  Anyone have a contact at Cloudflare they can share to get this resolved for the school district?
