3ms indicates you're hitting an instance that is fairly close by, network-wise.
Looking at your traceroute:
3 7 ms 13 ms 15 ms 10.98.0.233
4 7 ms 5 ms 4 ms one.one.one.one [1.1.1.1]
The instance is apparently on the same subnet as your CGN exit point. As such,
unless CloudFlare is deploying a *lot* of anycast instances, most people are
not going to have the joyous experience you have.
>From my desktop, 1.1.1.1 is 7 network hops away, compared to 8.8.8.8's 10 hops,
but the extra 3 hops inside AS15169 probably don't leave the building, and may
not even leave the rack. Both are right around 6.9ms away - while *our* network
presence there is 4 hops and also 6.9ms away and traceroute is showing jitter
larger than the difference between our router and either DNS service...
