This is true only for very small values of "used."  None of the above three servers answer authoritatively for this zone.. so while google and level3 may be listed in the delegation, I'm not sure I'd say they're being used as authoritative servers.  Considering that it's currently impossible to resolve this zone, it's probably not responsible for any query traffic from Chris's recursive server.
