1.1.1.1 will see the query regardless of caching by upstream servers. Downstream and client caching probably averages out quite nicely with enough volume.
If the TTL of one domain’s records are all shorter than the TTLs of another domain’s, what would make downstream and client caching cancel out? Do clients not respect TTLs these days?
(In this particular case, I don’t think the TTLs are actually different, but asking in general)
