             The September 2002 Netcraft Web Server Survey is out;

  Around the Net

   Microsoft gains 3% this month as register.com [1]continues to
   fluctuate between using a Windows and Linux front end. With the
   register.com domain parking system causing a 3% move in the by
   hostname count whenever it flips between Linux and Windows [though
not   making any great impact on active sites], we think presenting a
view   of the web counting by ip address has merit. This has the effect
of   boiling off all domain parking, HTTP/1.1 shared hosting, and
   eliminating duplicate counting of the same server when multiple
domain   names, such as [2]netcraft.com, [3]netcraft.net and
[4]netcraft.co.uk    all point to the same site.

   When counting by ip address, the supposed volatility of the past few
   months disappears, with Apache showing a three percentage point
   increase from 51% to 54% since the start of 2001, and Microsoft
   unchanged at 35%.

   Finding Application Servers

   "Can the Web Server Survey identify application servers?" has been a
   common question. The strictly correct answer is "no". However, we
have   noticed that sites running the IBM and Oracle personalised
versions of   the Apache web server very often are also running
application servers   from those vendors, and in practice this seems to
be a reasonably good   indicator.

   Plotting the numbers of ip addresses responding using these servers
   over the year to date shows some interesting things. As expected, IBM
   seems to have a significant lead over Oracle, but perhaps by less of
a   margin than expected, given the publicity and attention span
generated   by Websphere product marketing. There is also a strong
regional   divergence, with IBM doing much better than Oracle in the US,
but this   lead being less pronounced in Europe & Asia.


    Solaris sites curiously slow to upgrade

   A couple of months ago we highlighted the low numbers of sites
   migrating to Apache/2.0, and contrasted it with the speed at which
   site administrators adopted Apache/1.3.26 which contained a fix for a
   potential buffer overflow problem.

   If anything, more surprising is the slow adoption of new versions of
   Sun's Solaris operating system. Solaris 9, released in May this year,
   is running on fewer than 1000 web site ip addresses found by the
   September survey, and there are roughly twice as many sites running
   Solaris 2 & Solaris 7 as are running Solaris 8, released in March
   2000.

        OS       IP Addresses
    Solaris 2/7       165,527
    Solaris 8          81,730
    Solaris 9             987

   Historically, slowness to gather upgrade revenue has usually been a
   portent of trouble for web technology vendors, and the figures
   coincide with Sun's difficulties generating revenue and profits over
   the last eighteen months. By contrast, Windows .Net Server, which is
   not yet scheduled for release, has almost as many as ip addresses as
   Solaris 9, including some impressive high volume sites, such as
   [5]Nasdaq.  Sun would reasonably point out that their boxes typically
   cost a lot more, and the upgrade cycle for more expensive kit could 
   be expected to be slower.
