But there're many root servers, for example f.root-servers.net can be reached, why slashdot.org can be resovled? Try these two commands:

leo:~# dig www.slashdot.org

; <<>> DiG 9.2.1 <<>> www.slashdot.org
;; global options:  printcmd
;; connection timed out; no servers could be reached
leo:~#
leo:~#
leo:~#
leo:~#
leo:~#
leo:~# dig wwwwww.slashdot.org

; <<>> DiG 9.2.1 <<>> wwwwww.slashdot.org
