While KC is obviously best person to answer,  my understanding is  
that with the disapearence of ATT inside of SBC and the disappearance  
of MCIUUNET inside of Verizon all their traffic that CAIDA used to  
get was pulled.  CAIDA gets it no longer because now it is  
proprietary.  IMO a bad situation
