Web server market share for active sites

By doing January 2021 Survey from which we received responses 1,197,982,359 Websites about 262,949,225 unique domains and 10,649,817 Computer facing the internet. That is a gain of 95,900 computers but a loss of 30.13 million websites and 465,000 domains.

Apache, Nginx, and Microsoft all lost websites this month. Apache suffered the biggest losses with 16.4 million fewer websites, a significant portion of which came from a single hosting provider, Enzu. It was followed by Nginx, which lost 11.9 million websites, and Microsoft, which lost 7.8 million. Both posted losses with a number of hosting providers. nginx continues to lead in market share with 33.3% (-0.15 pp), ahead of Apache with 26.4% (-0.7 pp).

The number of domains operated by these web servers has also decreased this month. Microsoft saw the biggest drop of 2.2 million domains, while Nginx and Apache lost 903,000 and 303,000, respectively. This resulted in a small loss of market share for all three. The biggest drop was at Microsoft, which fell 0.8 percentage points to 6.3%. nginx lost 0.3 percentage points of its domain market share but still accounts for 30% of all domains. Most of the domains lost by these largest web server providers remain in the survey, with individual hosting providers switching large numbers to other server providers. One such move affected around 1.2 million domains hosted by Cogeco Cable Canada that were previously identified as nginx but are now responding with a DOSarrest server banner.

Despite these losses, the total number of web computers for Apache and Nginx increased that month. nginx won 68,000 computers and increased its market share by 0.3 percentage points to 34.7%, while Apache’s small growth of 6,200 led to a slight decrease in market share to 33% (-0.2 percentage points).

While both have a small market share in Internet-connected computers, LiteSpeed ​​and OpenResty saw good relative growth this month. LiteSpeed ​​won 3,400 computers (+ 7.7% compared to last month) and OpenResty 5,700 computers (+ 6.8%).

The number of millions of websites operated by Apache, Microsoft, and LiteSpeed ​​has increased this month. Apache saw the highest growth with 4,043 locations, increasing its market share to 25% (+0.4 percentage points) and maintaining its lead over Nginx, which lost 105 locations this month. LiteSpeed ​​added 1,700 new websites, a 9.4% increase from December.
