This month is the first time that a Windows 2000 site has appeared in the  50 top sites which have the longest period of time since last reboot. www.byteandswitch.com has been running continuously since November 2000. When we first started graphing web servers uptime in the summer of 2000, many people were skeptical that a Windows machine would ever make the top 50. Perceptions change, and although two years is exceptional, several Windows 2000 sites have run for more than a year without a reboot. In the hosting industry, Microsoft partners Interliant and Devine each have sites that have not been rebooted in over a year, while Microsoft has also run several of its own sites for over a year between reboots.
