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

Excellent public studies of Internet traffic by protocol exist from
NSFNet times up to 2002 or 2003; we thank Odlyzko, Claffy et al for
their work.
However, has anyone else noticed a serious lack of data after the
end of the studies summarised in "Longitudinal study of Internet
traffic 1998-2003", Fomenkov, Keys, Moore & Claffy, 2003? (This
has been discussed in the past, I think.) All that seems to be
available is vendor handwaving of the sort Andy Odlyzko takes so
much trouble to debunk; and that without any source data.
Curiously, no-one seems to be funding this stuff in Europe, either.
