Recent Changes at Notable Sites

www.digital.com was recently relegated to being a CName for www.hp.com, with the consequence that requests for www.digital.com now report the site as running HP-UX, a poignant moment for the company that brought the world RSX, VMS, and Ultrix.

Similarly, Netscape, whose founding employees pioneered the web server, replaced Netscape-Enterprise with AOLServer a few months ago.

www.army.mil has recently moved to MacOS X in its first switch since 1999, when it migrated to the Apple platform in the aftermath of a successful attack on its then Microsoft based web site. Ironically, Apple has recently replaced MacOS X with Solaris for its own Knowledge Base site.

The Washington Post has become of the first big name media sites to adopt Solaris 9. It is currently deployed in a load balancing pool where approximately a quarter of requests are met by Solaris 9 machines. To date, only a handful of Sun's own sites have been switched to Solaris 9.

One site that has not changed is www.sco.com, where people continue to delight in the irony of SCO using the operating system whose deployment they are seeking to restrict.

www.af.mil moves to Cable and Wireless, replaces Sun with Microsoft

The US Air Force has moved its most public site away from the Defense Technical Information Center to a commercial hosting datacenter at Cable & Wireless. Microsoft will be delighted to have replaced Sun as the server platform. In 1999 Microsoft suffered the indignity of the main US Army web site operations staff not only replacing Microsoft servers with Macs but also giving their opinion of Microsoft product security on the front page of www.army.mil.

However, Cable & Wireless have subsequently announced their intention to sell or close their US datacenters, which may mean that www.af.mil will move again. Since this was not completely unexpected, it makes the timing of the US Army's move seem curious.

May 2003 Web Server Survey

The Netcraft Web Server Survey is a survey of Web Server software usage on Internet connected computers. We collect and collate as many hostnames providing an http service as we can find, and systematically poll each one with an HTTP request for the server name.

In the May 2003 survey we received responses from 40,444,778 sites.

Where are the Windows Server 2003 sites hosted?

Some people expressed surprise that there could be thousands of sites running on Windows Server 2003 before it went on sale. The main reason for this is that some shared hosting providers who were part of the Windows Server 2003 beta program were prepared to run part of their sites on Windows Server 2003 prior to launch. The three providers with the largest number of active sites on Windows Server 2003 are all Microsoft Certified Partners while the fourth largest is Microsoft itself. No one else had more than 1000 active sites running on Windows Server 2003 at the start of May.

For comparison, Schlund and Interland [primarily due to its acquisition of Dialtone Internet] are also two of the largest Linux hosting providers, along with specialist Linux hosting providers Rackshack and Alabanza.
