The new Netcraft numbers are out. And the Internet-usage-tracking organization notes that the number of Windows Server 2003 sites is continuing to grow, primarily as a result of upgrades from older versions of Windows. But defections from Linux to Windows 2003 also are continuing at a constant clip, according to Netcraft. "Notably, the number of sites switching from Linux has proportionately kept pace since July when many commentators thought the 5% of sites switched to Windows 2003 from Linux was an aberration," says Netcraft.
