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...
