In the March 2018 survey we received responses from 1,770,411,187 sites across 214,774,438 unique domain names and 7,333,606 web-facing computers. This reflects a gain of 43,000 computers, and 738,000 additional domains. The total number of hostnames fell by 68.2 million, and the number of active sites fell by 3.4 million.

Domain growth this month was shared between nginx and Microsoft; nginx increased its market share by 0.15 percentage points by gaining 482,000 domains while Microsoft gained slightly fewer with 413,000. Market leader Apache lost 568,000 domains and continues to lose market share, its share now stands at 37.6%.

Apache also loses out when looking at the number of web-facing computers, 31,000 fewer computers were seen running the web server software in March leading to a drop in market share of 0.67 percentage points. Microsoft also lost computers, seeing 100 fewer, while nginx continues to gain both computers and market share. Nearly 1.8 million web-facing computers were seen running nginx in March, giving it 24.5% of the market.
