Internet services company Netcraft analysed around four million Web sites
to find what Linux distribution each site's Web server was running. It found
that over 400,000 sites were running Fedora in March, an increase of 122 percent
since September last year.

The number of Web sites running Red Hat Enterprise Linux
decreased by almost 20,000 over the last six months, although it remained the
most common Web server operating system with over 1.61 million deployments (out
of the four million Web sites surveyed).

Colin Phipps, a developer at Netcraft, said that usage of
Red Hat Enterprise Linux has been dropping off since Red Hat changed its
licensing model. In 2003 Red Hat caused href="http://insight.zdnet.co.uk/software/linuxunix/0,39020472,39116667,00.htm">controversy
by increasing the price of its commercial offering. At the same time it href="http://news.zdnet.co.uk/software/linuxunix/0,39020390,39117666,00.htm">created
Fedora, a free Linux distribution for hobbyists.

After Red Hat changed its licensing models some Web site
administrators migrated to other distributions, rather than switching to Fedora,
said Phipps. But this now appears to be changing.

"We saw a boost in Debian around the time that Red Hat made
a change in its licensing model," said Phipps. "Fedora was a really new name so
a lot of new sites that were setting up chose to go with Debian or SuSE instead.
Fedora has now overcome this obstacle."

Other Linux distributions have increased in use among Web
site administrators in the last six months. Free distributions Debian and
Gentoo, and commercial distributions Mandrakesoft and SuSE have increased by 14,
45, 17 and 11 percent respectively.

Phipps admitted that commercial distributions such as Red
Hat Enterprise Linux and Novell SuSE are likely to be overrepresented in the
Netcraft survey as the survey is based on information contained in their Apache
headers, which are less likely to be changed in out-of-the-box installations.
