Netcraft Web Server Survey Results for September Out: Apache, Linux Up

Oct 01, 2001, 16:17 (10 Talkback[s])

Netcraft's September Web Server Survey results are out. According to the report, Apache grew in share by 1.43% and Linux, which continues to displace proprietary Unix and, to a lesser degree, the BSD family, grew by 1%. Interesting statistics and insight to be found regarding the post-CodeRed Web as well.

"Microsoft Windows has a significantly higher share of the web when one counts by computer, rather than by host, as in the conventional Web Server Survey. The survey shows 49.6% of the computers running the web are Windows based. As some of the 3% of computers not identified by the Netcraft operating system detector will in reality be Windows systems, despite some uncertainty due to the survey's error margins, it would be fair to say half of public Web Servers world-wide are run on Microsoft operating systems. Although Apache runs more sites than Windows, Apache is heavily deployed at hosting companies and ISPs who strive to run as many sites as possible on a single computer to save costs. Windows is most popular with end-user and self hosted sites, where the host to computer ratio is much smaller.

Linux is the second most commonly used operating system. Linux has been consistently gaining share since our analysis started, but interestingly not significantly to Windows detriment. Operating systems which have lost share have been Solaris and other proprietary operating systems, and to a smaller degree BSD operating systems.

Compared to the previous quarter's results, Linux has gained 1% and Windows 0.3%, at the cost of the other operating systems. In fact the 0.3% Windows gain is largely a technical improvement, due to Unknown dropping 0.6% because of improvements in Netcraft operating system detection. The trend is of Linux steadily increasing, Windows maintaining a large share, and the others slowly losing share."
