October 2014 Web Server Survey

In the October 2014 survey we received responses from 1,028,932,208 sites, which is nearly six million more than last month.

Apache regains the lead

Microsoft lost the lead to Apache this month, as the two giants continue to battle closely for the largest share of all websites. Apache gained nearly 30 million sites, while Microsoft lost 22 million, causing Apache to be thrust back into the lead by more than 36 million sites. In total, 385 million sites are now powered by Apache, giving it a 37.45% share of the market.

A significant contributor to this change was the expiry of domains previously used for link farming on Microsoft IIS servers. The domains used by these link farms were acquired and the sites are now hosted on Apache servers at Confluence-Networks, which display Network Solutions parking notices.

A new major release in the Apache 2.2 legacy branch was announced on 3 September. Apache 2.2.29 also incorporates many changes — including several security fixes — from version 2.2.28, which was not officially released. New versions of nginx stable and mainline were also released during September, which included fixes for an SSL session reuse vulnerability, plus several other bugfixes.

Top million sites

The million busiest websites now represent less than 0.1% of all websites in the survey, but provide an insight into the preferences amongst the sites which are responsible for the great majority of today's web traffic.

Just over half (50.2%) of the top million sites use Apache, which is very similar to its share amongst all active sites; however, nginx's market share is skewed noticeably higher amongst the top million sites, where it powers 20.3% of sites, compared with only 14.3% of all active sites.

Computer growth

The most stable metric is the market share of web-facing computers — hundreds of thousands of websites can easily be served from a single computer (and subsequently disappear all in one go) but it is obviously far less trivial and less desirable to deploy or decommission a significant number of computers. Netcraft's survey is also able to identify distinct computers which use multiple web-facing IP addresses, which adds further stability.

Apache leads in this market with a 47.5% share, and Microsoft also performs well with 30.7%, but both have been gradually falling over the past few years as a result of nginx's strong growth. nginx gained more than 17,000 additional web-facing computers this month, helping to bring its market share up to 10.3%.

New top level domains

The relatively new .xyz domain, which showed tremendous growth over the past couple of months, has started to flatten out slightly after gaining only 33,000 sites this month (+8%). Nonetheless, this is still quite a healthy gain, albeit notably less than last month's growth of 177,000 hostnames which then boosted its total by 78%.

Other promising TLDs include .london, .hamburg and .公司, each of which had fewer than 50 sites in last month's survey, but now have 17,000, 11,000 and 10,000 sites respectively.

The internationalised .公司 (.xn--55qx5d) TLD is delegated to the Computer Network Information Center of Chinese Academy of Sciences. It means "company", making it the Chinese equivalent of .com.
