Microsoft has gained 16.5 million hostnames, while Apache has lost 1.8 million, according to the Netcraft survey for October 2013.
Netcraft received responses from over 767 million sites, an increase of over 28 million from last month’s survey.
Apache’s market share fell to 45 percent, the lowest it has been since January of 1998, when its market share represented a mere 830,000 hostnames. Apache gained 18 million new sites this month, while 16 million of the sites it served closed down and another 4 million migrated. Of those, 1.5 million moved to nginx and 420,000 moved to Microsoft.
SSL survey results also showed a drop for Apache, but it continues to lead that market at 43 percent.
Apache’s market share of hostnames was 53.4 percent in May of 2013, but that same month a backdoor malware scare hit Apache, and its dominance has been slipping since.
Microsoft’s gain grew its lead over nginx to almost 5 percent, after the gap between them had shrunk to only 1 percent in May. Microsoft also has made its IIS/8.5 server available to MSDN and TechNet subscribers, and it will be released to the public on Oct. 18.
Nginx did gain over 11M hostnames in the past month, with a net gain from Apache but a small net loss to Microsoft. Nginx also gained 4,400 hostnames among the top million, and sits at 15 percent.
All major server vendors suffered losses of active sites, for a net decrease of 780,000, according to the active sites metric. The majority of those losses were suffered by Apache. The number of inactive sites overall continued to rise, with less than a quarter of sites deemed active, down from 44 percent in 2000, when Netcraft began measuring active sites.
