In the July 2021 survey we received responses from 1,216,435,462 sites across 262,098,666 unique domains and 11,260,130 web-facing computers. This reflects a gain of 3.16 million sites, 1.99 million domains, and 161,000 computers.
nginx gained the largest number of sites, computers and domains this month – and continues to lead in each of these metrics – but it lost the most active sites, and its presence amongst the top million sites also fell by the largest amount. The largest active sites gain was made by Google (+1.02 million), while Cloudflare was the only major vendor to increase its share amongst the top million sites (+1,732).
Despite strong growth by Google and Cloudflare, Apache still has the largest number of active sites and greatest presence within the top million sites, while nginx is second in both of these metrics.
nginx's gain of 7.99 million sites was followed by an additional 1.36 million sites powered by OpenResty, which is a web server based on nginx. More than 12 million of the 75.4 million sites that use OpenResty are Tumblr microblogging websites under the tumblr.com domain.
OpenResty was originally sponsored by Yahoo! China and Taobao prior to 2011, but Taobao now maintains its own Tengine web server, which is also based on nginx. This is currently used by 11.3 million websites, including 3.13 million C2C ecommerce sites that use the taobao.com domain and 265,000 sites like disney.tmall.com that use the Tmall.com B2C platform.
The number of websites powered by Microsoft IIS (Internet Information Services) fell by 1.92 million to 51.6 million this month. These sites are spread across 13.5 million unique domains and use several different versions of IIS.
The widespread use of several different versions of IIS is likely to continue as Microsoft announced Extended Security Updates for Windows Server 2012 and 2012 R2 on 14 July. Customers who migrate their workloads to Microsoft Azure will get free extended security updates for three more years, while those who choose to run Windows Server on-premises will have the option to purchase the updates. These versions of Windows Server provide the IIS 8.0 and IIS 8.5 web server software, which is still used by 21.4 million websites in this month's survey.
One year of extended security updates are also available for Windows Server 2008 and 2008 R2 on Azure only. These older versions of Windows Server use IIS 7.0 and IIS 7.5, which are still used by 15.7 million websites.
The latest version of Microsoft's web server software, IIS 10.0, is currently used by 12.1 million websites. This version can be found on Windows Server 2016, Windows Server 2019, and can also run on the preview version of Windows Server 2022.

Its lead in this metric continues to steadily grow, with Apache’s share in second place dropping to 31.7% — a gap of over half a million web-facing computers.
LiteSpeed saw the only other notable increase in web-facing computers, with an additional 10,400 (+17.6%) boosting its total to 69,500 web-facing computers. LiteSpeed also gained the 2nd largest number of domains this month, with an increase of 289,000, increasing its total to 5.75 million.

Meanwhile in the web-facing computers and top million busiest sites metrics, Microsoft instead had the largest losses of 21,600 computers and 3,700 of the million busiest sites, followed by Apache with a loss of 15,400 computers and 2,500 of the million busiest sites. Despite its losses in these metrics, Apache continues to power the largest number of active sites with a share of 24.8%, and top-million sites with a share of 25.2%.

Rackspace was the most reliable hosting company site in May 2021, taking the top spot for the third time in the past 12 months, and appearing in the top 10 for 10 of the last 12 months. The top six hosting companies all responded to every request from Netcraft, and are ranked by the average connection time. Rackspace had the lowest average connection time of the six, earning it the title of most reliable hosting company site in May 2021. Rackspace offers a variety of cloud hosting solutions from 40 data centres across five different continents in the Americas, Europe, Asia and Australia.
In the May 2021 survey we received responses from 1,218,423,991 sites across 259,596,021 unique domains and 11,051,830 web-facing computers. This reflects a gain of 6.28 million sites and 112,000 computers, but a loss of 4.87 million domains.
nginx gained the largest number of hostnames, active sites, and computers this month; but also suffered the largest loss of 4.73 million domains. Its most notable gain was of 78,900 computers (+2.03%), which increased its leading share to 36.0%. It also continues to lead in the hostnames and domains metrics, while Apache is top in active sites.
Apache also maintains its lead amongst the top million websites, with a 25.4% share compared to nginx's 22.9%. Cloudflare's share of the top million sites is now up to 17.0% after increasing its presence by a further 3,090 sites, and Microsoft added 1,840 sites to bring its share up to 6.85%.
OpenResty saw the largest decrease of 8.10 million hostnames (-9.88%), which has taken its market share down to 6.06% (-0.7 pp). Microsoft also suffered a large loss of 6.92 million sites (-10.3%), which took its share down to 4.95% (-0.6 pp).
One of OpenResty's most prominent users is Automattic, which uses it to serve millions of Tumblr microblogging websites that can be found under the tumblr.com domain – for example, icontherecord.tumblr.com.
Automattic is also responsible for the popular WordPress.com blogging service, where it instead uses nginx to serve millions of blogs. These WordPress-powered sites can either use custom domain names, or free blogs can be created directly under the wordpress.com domain – for example, catsbeingcats.wordpress.com.
The underlying WordPress blogging software reached its 18th birthday this month. Automattic continues to contribute to this open source project, and the software is freely available from wordpress.org, allowing anyone to download and install the software on other compatible web server platforms. Although Apache and nginx are recommended, any server that supports PHP and MySQL ought to be capable of running a WordPress site. Such is the popularity of WordPress, some hosting providers also provide one-click installers and other tools that make it easy to manage WordPress sites.
