When we first reported on Windows Server 2003 we gave an indication on the numbers of sites that had been put up prior to the official launch. In the three months since the launch the number of active sites has increased by over 300% and now stands at 88,400.

Windows Server 2003 Growth – July 2003

Largest Microsoft Windows Server 2003 hosting companies by Active sites, July 2003 Company Active Sites   Myhosting.com 13,504   Fasthosts 11,978   AdvancedAccess 10,301   Interland 6,655   Internap 4,729   ViaWest 4,476   1&1 Internet 3,790

Over the past 3 months many new hosting providers have released Windows Server 2003 hosting packages. Myhosting.com is now the top hoster of active Windows Server 2003 sites, and apparently has stopped offering Windows Server 2000 and Microsoft-IIS/5.0 to new customers, inisisting that they should run Microsoft-IIS/6.0.

Comparing the sites which are now hosted on Windows 2003 with their operating system in December 2002 shows over 42% of these to be new sites, 43% (68K) to be upgrades from other Windows platforms (mainly Windows 2000), 5% (8K) to be migrations from Linux and 1% from other operating systems.

Microsoft will take some considerable encouragement at the number of sites that have switched from Linux.
