June 2019 Web Server Survey

In the June 2019 survey we received responses from 1,333,421,275 sites across 236,991,999 unique domain names and 8,840,331 web-facing computers. This reflects gains of 6.76 million sites, 1.98 million domains, and 113,000 computers.

nginx has further extended its lead in the hostnames metric, with 52.2 million additional sites pushing its total up to 440 million. Since overtaking Apache in April, nginx has already built up a 4.89 percentage point lead over Apache's market share and is not far off accounting for more than one third of all sites.

Apache retains the lead in all other metrics, but for how long? The proportion of unique domains that are served by Apache has fallen to 30.1%, while nginx snapped up the majority of this month's net domain growth, bringing its share to within 3.4 percentage points of Apache's. There has been a clear trend of Apache's domain market share decreasing, while nginx's increases and looks likely to overtake Apache within a year. A similar trend is evident in web-facing computers and among the top million sites, so it may not be long before nginx steals more of the limelight.

Reports of a remote code execution vulnerability in most recent versions of nginx were downplayed by its developers, who claimed that neither of the two overflow vulnerabilities appeared to be generally exploitable. Both bugs affected the njs scripting language implementation that allows nginx's functionality to be extended; one bug was fixed in njs 0.3.2, which was released on 21 May along with nginx 1.17.0, while the other bug is expected to be fixed in the future release of njs 0.3.3.

Several other product updates were also released during May, including NGINX Unit 1.9.0, lighttpd 1.4.54, LiteSpeed Web Server 5.3.8 (Stable), OpenLiteSpeed 1.5.1, and cPanel & WHM 80. The latest version of cPanel & WHM adds the ability to run Node.js applications, manage API tokens to allow resellers and third-party developers to run API functions, and ensure visitors are redirected to the secure HTTPS versions of sites.

Envoy – the open source edge and service proxy for cloud-native applications, which leapt to prominence in last month's survey – remains in tenth place with around 5 million sites, which are spread across 2.7 million unique domain names.

Cloudflare's web server has moved up into fifth place after gaining more than 5 million websites, giving it a total of 35.1 million sites across 12.9 million domains. The Cloudflare server is used by the edge nodes of Cloudflare's content delivery network, which now serves 2.6% of all sites in this month's survey.

Microsoft saw losses in every metric this month, apart from web-facing computers, where it made a gain of 13,600; however, this was not enough to stop its market share falling slightly, while Apache gained 17,300 computers and nginx gained 64,000.
