Around the Net
Apache broadly maintained its share this month with a gain of three
quarters of a million sites. The first European Apache Conference was
recently announced, with [1]Apachecon being held in London from
October 23-25th. [2]Weblogic gains some 90,000 sites overtaking thttpd
and Zeus. The great majority of the new sites are hosted on the fast
growing [3]NameZero hosting service located at [4]Exodus.
Microsoft [5]announced a new tool aimed at giving hosting companies
the capability of producing Windows 2000 based web sites more quickly.
The tool has been codeveloped with [6]interland.net who are currently
the largest hoster of Windows 2000 sites in the US, with around 2,500
sites. Interland also have around 30,000 sites hosted on Linux, and
some 60,000 on NT4. Windows 2000 has yet to see significant takeup
with hosting companies, but this was clearly set out as a goal for
Microsoft by Steve Ballmer in the advent of the Windows 2000 launch.
Dogfood
[7]HotMail has commenced its much awaited migration to a Microsoft
operating system. Some Windows 2000 machines have recently been moved
into the load balancing pool, with currently between 90-95% of
requests being served by the established FreeBSD/Apache platform, and
5-10% from Windows 2000. The Hotmail site infrastructure is enormous,
and even if everything runs smoothly, a migration will likely take
several weeks. [8]LinkExchange, the other prominent FreeBSD site
owned by Microsoft, still runs [9]FreeBSD but redirects users to
[10]BCentral.
How many Active Sites are there?
Over the last two years there has been significant growth in the
internet's DNS, fueled by rife domain name speculation, falling
registration prices, easier and more efficient administrative
procedures, and widespread publicity. It has become more common
practice for companies offering internet registration services to
place a template site on the web for each domain that they register.
Additionally, some hosting service companies find it convenient to
create new sites at the time of customer signup, rather than at the
point at which the customer is prepared to place real, personalised
content on to the web.
The biggest domain registries are large enough to be significant even
in the context of the 17 million sites found by the June 2000 Web
Server Survey. For example, [11]register.com host some 1.4m domain
names, the great majority of which are template sites. [12]Network
Solutions have a system hosted at [13]Digex which hosts around 750,000
template sites for domain name holders. These two domain name
registries presently account for about 12% of the hostnames found in
the Web Server Survey.
Additionally, many companies will register in more than one domain.
For example, Netcraft holds the netcraft.com, netcraft.net, and
netcraft.co.uk domains, and currently uses three hostnames that will
resolve to the Netcraft site. This means that there are nine names in
the DNS that will resolve to the same content.
Circa 1996-7, the number of distinct IP addresses would have been a
good approximation to the number of real sites, since hosting
companies would typically allocate an IP address to each site with
distinct content, and multiple domain names could point to the IP
address being used to serve the site content.
However, with the adoption of HTTP/1.1 virtual hosting, and the
availability of load balancing technology it is possible to reliably
host a great many active sites on a single [or small number of] ip
addresses. For example [14]FreeServe has around 150,000 sites hosted
on four load balanced IP addresses. These are substantially all active
sites produced by real people crafting HTML in FrontPage, Word,
Netscape, text editors, etc.
Netcraft has developed a methodology to determine the numbers of
active sites on the web. Details are on the main [15] survey page.
Results
The June 2000 "normal" by-hostname survey found a shade over
17 million sites. Nearly 10 million of these sites are removed
from the survey by applying the active sites methodology which
found 7.5 million active sites on 3.4 million IP addresses.
Apache loses 6,205,474 sites, causing its share to drop around three
percentage points from 62.53% to 59.56%. Netscape-Enterprise loses
957,629 sites, making its share drop from 6.74% to 2.61%.
Microsoft-IIS loses 1,458,421 sites, so its share of the survey rises
some six and a half percentage points from 20.36% to 26.84%.
Compared with the by-hostname survey, Linux drops by 6%, Solaris by
4%, NT gains 7%. Other O/S's each gain by a little. On active sites
Linux & NT are very close, with Linux having slightly more than a 1%
lead over the combined figure for NT4 and Win2000.
OS Hosts % Active %
Linux 6,116,811 35.73 2,265,095 29.99
Microsoft 3,644,187 21.32 2,222,841 28.32
Other 3,802,268 21.24 1,873,525 23.59
Solaris 3,484,135 20.35 1,233,494 16.33
unknown 233,676 1.36 132,862 1.76
As expected, a sizeable chunk of the Linux drop is at [16]register.com
which has around 1.3m inactive sites. Likewise [17]Network Solutions
accounts for somewhere over 800,000 inactive Solaris sites.
Conversely, [18]theplanet.net which hosts FreeServe, the
largest UK dial-up ISP with around 1.3m active subscribers, only falls
by about 20%, maintaining 136,000 of around 170,000 sites. This is a
nice test case for the methodology, as FreeServe is a large number of
active sites on just four IP addresses using http/1.1 virtual hosting.
Of the 3.3 million IP addresses with active sites, the great majority,
3.2 million, have just a single active site on them. At the other end
of the scale the largest number of active sites on a single IP address
is 286,620 at [19]Webjump.
Essentially, the domain name registries disappear, and the cheap or
free bulk hosters come to the fore, together with the larger
colocation companies such as exodus.net who may provide
connectivity for "downstream" bulk hosters. This is exactly as one
would predict.
NT and Windows 2000 are much more fully represented in this
analysis, but the success of Linux with the hosting companies is also
very clear. Solaris is being pushed further upmarket by the
combination of Linux and NT, and does well in specific high volume
transaction environments such as internet brokerage.
Your [21]comments and criticism are much appreciated.
