Here is what I get:
<stora:~ 7:55 8 0>dig any . @m.root-servers.net.
;; Truncated, retrying in TCP mode.

; <<>> DiG 9.6.1-P1 <<>> any . @m.root-servers.net.

Thus I think the any-cast instance you are using is the broken one,
I'm talking to the one on the west coast of the US. (SFO ?).

traceroute to m.root-servers.net (202.12.27.33), 64 hops max, 40 byte
