May 2018 Web Server Survey

In the May 2018 survey we received responses from 1,584,940,345 sites, 217,875,435 unique domains, and 7,452,628 web-facing computers. This reflects a loss of 198 million sites, but a gain of 3.36 million domains and 65,600 web-facing computers.

nginx saw moderate growth this month, gaining 1.17 million unique domains. This has increased its market share of domains by 0.19 percentage points, even though it lost 44.2 million sites.

The nginx ecosystem has continued to evolve over the past month, with some notable software releases:

  • nginx 1.14.0 was released on the 17 April, which adds HTTP/2 server push support to the nginx stable stream (the recommended release stream for production web servers). HTTP/2 server push can improve the performance of some websites by pre-emptively pushing assets to browser clients, avoiding the need for the client to explicitly make additional GET requests for assets on a page such as images, stylesheets & JavaScript.
  • The first production-ready release of NGINX Unit 1.0 was released on the 12 April, ending the product's beta period. NGINX Unit is a web application server that can serve sandboxed Go, Perl, PHP, Python and Ruby applications on the same server. It is unique in allowing dynamic reloading & remote configuration via a REST API rather than individual configuration files. A bugfix release, NGINX Unit 1.1, was subsequently made available on 26 April.
  • MySQL monitoring support was added to NGINX Amplify on 23 April. This commercial SaaS monitoring product from NGINX Inc. could increase the appeal of transitioning MySQL & PHP applications from Apache-based stacks to nginx-based ones.

Despite losing 59.7 million sites this month, Apache still powers sites on the largest number of unique domains. Apache is also running on 36% of the world's top 1 million websites – 12 percentage points ahead of its closest competitor, nginx.

There was also a 21% reduction of the number websites running Microsoft web server software this month, with the majority of these losses (77%) coming from hosting provider Raksmart, which lost 107 million of these sites. Despite this, the hosting provider gained 49,600 domains that point to Microsoft web servers. Many of the lost websites featured automatically generated content, and so were not counted as Active Sites.
