January 2004 survey from 46,067,743 sites. This is 87,631 more sites than responded in December. Although it represents yet another peak in the number of responses received, the four top-four players, Apache, Microsoft, SunONE, and Zeus, remained flat, seeing growth of -0.05, 0.13, -0.07, and 0.00, respectively.
