April 2012 Web Server Survey

In the April 2012 survey we received responses from 676,919,707 sites, giving a rise of 32.6M hostnames (5.1%) since last month.

Apache saw the largest growth (22.8M) and increased its market share to 65.5%. nginx, with the second largest growth (4.5M), increased its total to 69.9M. Microsoft had a greater increase in hostnames this month (+3.5M) compared to March, however still experienced a small loss in market share.

Microsoft's new server operating system, codenamed Windows Server 8, which was released to MSDN subscribers in September 2011 has now been made available as a public beta. Microsoft-IIS/8.0 is the default web server on Windows Server 8, and the April 2012 survey found 278 sites with this server header. However, many of these sites are running on Linux, indicating proxy servers or forged server headers. The first sites deploying Windows Server 8 include iis.net, phponwindows.net, and a Microsoft corporate remote access service. Indicative of an early beta, many installations are on isolated broadband connections, rather than at large hosting providers.
