| This page shows web access statistics for KSC's toplevel Web server. Most of the peaks coincide with shuttle launches. KSC has a high speed OC-48 (2Gb/s) network backbone containing multiple high speed circuits. KSC's toplevel web server is a cluster of DEC Alpha Unix machines internally interconnected via Gigabit Ethernet switches and externally connected to a 100Mb/s FDDI backbone. Over the 6 years of operation, the general growth trend has been upward but constrained at various times by bottlenecks in the network pipelines between KSC and the Internet. KSC's home page went online in September, 1993. In January, 1995, KSC's available bandwidth to the Internet was increased from a fractional T-1 (512kb/s) to a dedicated T-1.(1.54Mb/s). In October, 1996, the bandwidth was increased again to an E-1 (2.0Mb/s). In July 1997, an additional circuit was added directly to MCI and KSC supported JPL as a Mars/Pathfinder mirror site. In October, 1998, KSC's bandwidth was increased in time for STS-95 to a DS-3 (45Mb/s) circuit via SPRINT's ATM network. On July 13, 2000, the WWW server was split into two servers. Pages geared for a general audience were moved to a new server that retained the name WWW.KSC.NASA.GOV.(Statistics for this server). All scientific and Technical pages were retained on the existing server which was renamed SCIENCE.KSC.NASA.GOV. Statistics Utilities:Statistics for 2004:Statistics for 2000:
