So I've tried from a few different networks in the SF Bay Area and
Level(3)'s anycast DNS servers seem to be having trouble resolving
anything.

4.2.2.1 through 6, and 209.244.0.3 and 4

% dig @4.2.2.2 google.com

; <<>> DiG 9.5.1-P3 <<>> @4.2.2.2 google.com
; (1 server found)
;; global options:  printcmd
;; connection timed out; no servers could be reached

They do still seem to have root hints though.

% dig @4.2.2.2

; <<>> DiG 9.5.1-P3 <<>> @4.2.2.2
