September 2019 Web Server Survey

In the September 2019 survey we received responses from 1,291,178,101 sites across 241,131,705 unique domain names and 9,068,313 web-facing computers. This reflects a gain of 19 million sites, 1.69 million domains and 119,000 computers.

All major vendors gained sites this month. The largest gain was for nginx with an increase of 20.6 million sites, followed by Microsoft (+2.9 million), Google (+2.1 million) and Apache (+462,000). This extends nginx's lead as the largest web server vendor by number of sites; it gained 1.12 percentage points taking it to a 32.7% market share. nginx also showed the largest gains in number of unique domains and web-facing computers.

The largest gain within the top million sites this month was by LiteSpeed, which also saw gains in hostnames, domains, and web-facing computers. The September survey saw 1,422 more sites within the top million using this light-weight Apache alternative, an 8.0% increase. This was accompanied by increases of 480,000 sites (+2.6%), 326,000 domains (+9.4%) and 1,665 web-facing computers (+8.1%).

There are losses in market share for both Apache and nginx as the largest server vendors by number of active sites. Apache lost 22,000 active sites while nginx gained 915,000; due to large gains elsewhere this amounted to Apache losing 0.94pp and nginx losing 0.11pp. Google gained 800,000 active sites and 0.16pp of market share to retake third place from Cloudflare; Cloudflare gained 591,000 sites. The largest increase of active sites was in sites running openresty with an increase of 1.04 million.
