An analysis of access statistics for the primary PDB Web site shows that the number of hits it has received has fluctuated a bit over the past few months, with monthly totals ranging between 2,460,455 and 3,545,612 hits. The total number of files downloaded per month ranges between 1,876,663 and 2,780,938 files. A new record of 3,545,612 Web site hits was achieved during the month of September 2000, which is 427,880 more hits than the previous record
month of March 2000. The number of files downloaded in September also reached a new record high of 2,780,938 files, which is 401,228 more files than were downloaded in March 2000.
We are pleased to see the tremendous amount of user interest during September, with a daily average of 122,262 hits and 95,894 files downloaded. School schedules probably have a significant impact on the large increase in the access statistics for that month, as our largest user group continues to be the U.S. educational institutions.
While the www.rcsb.org address continues to receive the most traffic, use of the mirror sites and beta test site continues to increase.
