If you go to http://mudcat.org/ you'll get an answer randomly from one of four servers, brownie.mudcat.org (96.89.184.227), sonny.mudcat.org (96.89.184.228), huddy.mudcat.org (96.89.184.229) and a fourth one with the IP address 96.89.184.230 whose name I don't know. This fourth server seems to be unreachable, so you have a 25% chance that your call to mudcat.org will hang.

If you choose either brownie, sonny or huddy, you'll get an answer.

By the way, "Huddy Leadbelly" is a song sung by Brownie McGhee and Sonny Terry on their album "California Blues". I wonder if this is the source of the server names.
