In the March 2014 survey we received responses from 919,533,715 sites — around half a million fewer than last month.
Apache has gained some breathing space this month. Nearly a year of strong market share growth by Microsoft eventually culminated in the gap between Apache and Microsoft being reduced to only 5.4 percentage points. After the gap dropped to its lowest point last month, Microsoft had looked set to usurp Apache as the most common web server within a matter of months. This month's survey saw Microsoft lose 15.8 million sites and Apache gain 3.2 million, however. Apache's market share increased to 38.6%, 7.5 percentage points ahead of Microsoft and bucking the recent trend.
Most of Microsoft's losses this month were seen at Nobis Technology Group, where more than 30 million link-farming sites stopped operating. Nobis is a private holding company, which owns the DarkStar voice communications network and Ubiquity Hosting Solutions, which has seven data centres across the United States.
nginx gained 5 million sites this month, increasing its market share to 15.6%. The latest mainline version of nginx (1.5.10) now supports SPDY 3.1, which extends the flow control features of SPDY 3.0 by allowing different sessions within a single connection to send data at different rates. It is no surprise that SPDY 3.1 is already supported in the Google Chrome web browser; SPDY was primarily developed by Google, and is one of their trademarks. SPDY 3.1 has also been supported in Mozilla Firefox since 4th February 2014.
Content delivery network CloudFlare — which uses its own web server software based on nginx — rolled out SPDY 3.1 support for all of its customers in February. Since last month, Netcraft's SSL Survey has identified a four-fold increase in the number of HTTPS websites supporting SPDY 3.1, most of which are hosted by CloudFlare. A smaller number of these SPDY 3.1 sites are hosted by the owner of the WordPress.com blogging platform, Automattic, which was one of the sponsors of the ngx_http_spdy_module.
Mozilla has been planning to remove SPDY 2 support from Firefox since September 2013, and this looks set to happen with the release of Firefox 28. Some developers asked for SPDY 2 support to be retained, arguing that dropping support for SPDY 2 would effectively drop SPDY support in many SPDY-enabled websites. However, nginx and CloudFlare now supporting SPDY 3.1 allays some of that concern.
LibreOffice — the free open source office suite bundled with Ubuntu Linux — moved its website from an Apache web server to nginx at the end of January, apparently for performance reasons. Incidentally, this further distances LibreOffice from the Apache Software Foundation - LibreOffice was forked from OpenOffice.org in 2010, before the latter was given to the ASF where development continued under the name of Apache OpenOffice.
More than 30 new generic top-level domains (gTLDs) were delegated to the Root Zone during February, making them officially part of the internet. There are now 471 top level domains in total. The new ones added in February included .flights, .wiki, .xyz, .fish and .移动 (xn--6frz82g – Chinese for "mobile").
Many of these new gTLDs were applied for by Donuts Inc, a US domain registry which was founded in 2011. The company's CEO and co-founder, Paul Stahura, previously founded domain name registrar eNom in 1997. Donuts raised more than $100,000,000 in its Series A financing round and applied to ICANN for more than 300 TLDs in 2012. As a registry, Donuts does not sell domain names directly to the public; instead, customers must purchase them from one of its accredited registrars.

In the February 2014 survey we received responses from 920,102,079 sites — over 58 million more than last month.
Microsoft gained a staggering 48 million sites this month, increasing its total by 19% — most of this growth is attributable to new sites hosted by Nobis Technology Group. Along with Microsoft, nginx also made a large gain of 14 million sites, whereas Apache fell by 7 million. Unsurprisingly, these changes have had a dramatic effect on the overall market share of each web server vendor, with Microsoft's share growing by 3.38 percentage points to 32.8% (302 million sites) while Apache's has fallen by 3.41 to 38.2% (352 million sites).
Microsoft's market share is now only 5.4 percentage points lower than Apache's, which is the closest it has ever been. If recent trends continue, Microsoft could overtake Apache within the next few months, ending Apache's 17+ year reign as the most common web server. Apache is faring much better in both the active sites and top million sites datasets, however, where it is still dominating with just over half of the market share in both metrics.
Nearly 2% of the top million websites are now being served by CloudFlare's customised version of nginx (cloudflare-nginx), which it uses to serve web content via its globally distributed CDN edge nodes. This month's survey saw more than a thousand of the top million sites migrate to cloudflare-nginx from other web server software, including pizzahut.co.uk, pet-supermarket.co.uk, the image server used by the popular Cheezburger network of blogs, and the official PRINCE2 website which switched from Microsoft IIS 6.0 running on Windows Server 2003.
Overall, nginx powers 17.5% of the top million sites, including popular overclocking forum www.overclock.net, despite its server headers declaring that it is now using Microsoft IIS 4.1. Responses from the server also include an X-Powered-By header which claims the application is running on Visual Basic 2.0 on Rails (Visual Basic 2.0 is a long-deprecated language which was released more than 20 years ago, while Microsoft IIS 4.1 never actually existed). The server claimed to be running nginx during Netcraft's previous survey, and indeed, it exhibits characteristics which suggest it is still using nginx.
The number of sites using the .pw country-code top-level domain (ccTLD) grew by more than half this month, reaching 10M sites in total. This ccTLD is assigned to Palau, but the .pw registry has branded the domain as the Professional Web and allows domains to be registered by the general public, regardless of which country they are in. 97% of this month's new .pw sites are hosted in the US (87% at Nobis Technology Group alone), and 2.7 million of them are running on Windows.
The busiest .pw domain is the single-letter u.pw, which is used by viral social media site Upworthy. Other than that, the ccTLD remains relatively obscure, with less than 0.02% of the top million sites using .pw domains, while other single-letter domains have been sold for the modest sums of $8,000 each. Only two single-letter .pw domains actually appear within the top million sites, and there are no two-letter domains at all. Last year, Symantec noted an increase in spam messages containing URLs with .pw TLDs, and .pw later became the first TLD to adopt the Uniform Rapid Suspension (URS) rights protection mechanism.
Version 1.0 of the URS Technical Requirements were published by ICANN in October 2013, and are intended to make it faster and cheaper for trademark holders to seek resolution when there are obvious cases of infringement. URS is intended to complement rather than replace the existing Uniform Domain-Name Dispute-Resolution Policy (UDRP).

In the January 2014 survey we received responses from 861,379,152 sites, an increase of 355,935 since last month.
2013 has been a year of significant change: the web has grown by more than one third, the importance of SSL has been highlighted by a series of spying revelations, Microsoft now power just below 30% of all web sites, and Apache has lost almost 14 percentage points of market share. Additionally, nginx, the relative newcomer, saw its market share peak at 16%, just shy of Microsoft’s position at the beginning of last year.
The total number of web sites discovered has increased dramatically this year — from 630 million web sites in January 2013 to 861 million in January 2014 (+37%) — though the growth does not compare to the doubling in size during 2011.
With the revelations from the NSA documents leaked by Edward Snowden providing months of mainstream publicity, 2013 has been a bumper year for the SSL industry. Websites are increasingly being served over HTTPS: 48% more sites within the million busiest are using SSL than in January 2013. In total, there are over half a million more SSL certificates (+22%) in use on the web since January 2013. The estimated total revenue of the industry has increased even more rapidly, by 28% from September 2012 to September 2013, reflecting the increased uptake of more expensive certificates including Extended Validation, multi-domain, and wildcard certificates.
Apache remains the most commonly used web server on the internet, 10 million more web sites are using it than this time last year; however, this growth has not been sufficient to maintain its share of a market which grew by more than 200 million web sites. As a result, Apache’s market share has fallen by 14 percentage points since January and now stands at 42%.
In stark contrast to Apache, Microsoft had a strong year — almost 150 million more web sites use a Microsoft web server than in January 2013. Microsoft’s share is close to 30% of the entire market and a combination of its strong growth and the corresponding lack of growth of sites using Apache has resulted in Apache’s lead shrinking by more than 26 percentage points to just 12. Microsoft's own cloud platform, Azure, has grown steadily throughout 2013 — there are 39% more web-facing computers hosted by Microsoft in January 2014 than the same time last year — and despite offering alternatives, Microsoft's IIS is by far the most common web server on Azure.
Open-source web server nginx has continued to gain acceptance, especially amongst the busiest web sites. Nginx is now used on 14% of all web sites found, up 2 percentage points since January 2013, but has fallen slightly from the peak of 16% it achieved in October. In May 2013, nginx overtook Microsoft to become the second most common web server within the top million busiest sites and now powers almost 16% of them.
Developer December 2013 Percent January 2014 Percent Change Apache 355,244,900 41.26% 358,669,012 41.64% 0.38 Microsoft 241,777,723 28.08% 253,438,493 29.42% 1.34 nginx 126,485,204 14.69% 124,052,996 14.40% -0.29 38,263,525 4.44% 21,280,639 2.47% -1.97
In the December 2013 survey we received responses from 861,023,217 sites, an increase of 75.7M since last month.
For the third consecutive month Microsoft experienced the largest growth in web server market share; an additional 51M sites boosted its market share by almost 4 percentage points. Apache had the biggest loss in market share, despite seeing an increase of 7M sites. Nginx’s growth this month has led to them regaining some of the market share lost last month, and results in a net gain of 3M sites over the last two months (a loss of 13M in November, followed by a gain this month of 16M).
Considering only active sites, Microsoft’s growth was significantly lower (compared to its gain of 51M sites) with an increase of 478k active sites. Apache saw the largest increase of 622k active sites, and increased its market share by 2 percentage points to 54%. Google meanwhile saw a large loss of 8.6M active sites within its App Engine service.
Microsoft's web server market share could see further gains from its own Windows Azure cloud service — Microsoft has made Azure more cost-effective with price reductions and a new enterprise plan. Microsoft also has plans to expand Azure into Brazil in 2014. Unsurprisingly Microsoft IIS is the most common Web Server seen on Azure, used by 87% of sites. Amazon followed Microsoft's price cuts by introducing price reductions on EC2 M3 Instances. At Amazon, 36% of sites are running on nginx, followed by Apache with 27% and Microsoft IIS with 14%.
ICANN has begun delegating new generic Top-Level Domains (gTLDs) from its new gTLD expansion program, adding them into the Internet's Root Zone. The first four gTLDs (شبكة, онлайн, сайт, 游戏) were delegated on October 23rd and a further 30 new gTLDs have been delegated throughout November. ICANN has a mandatory 30-day sunrise period following delegation where registries "complete a final process built into the new gTLD Program to protect trademark rights holders"; after this has passed the new gTLD can be made available to the general public at the registry's discretion. The شبكة dotShabaka registry was first to start its sunrise period on 31 October, this is to be followed by an (optional) Landrush Period before general availability commences on February 4th. So far the only sites found by Netcraft have been for the NICs (Network Information Center) themselves, such as: nic.游戏, nic.сайт, nic.онлайн, nic.شبكة.
The first gTLDs signed agreements back in July and more are being agreed each month. Recent notable gTLDs that have been agreed include the cities .london, .berlin, .budapest, .wein (Vienna) and .tokyo.

In the November 2013 survey we received responses from 785,293,473 sites, reflecting net growth of more than 18 million sites since last month.
Microsoft experienced the largest gains this month, with an additional 13.2 million sites taking its market share up by 1.15 percentage points. In contrast to recent trends, nginx's market share fell by more than 2 percentage points to 14.0% after it lost 13.1 million sites. Despite the absolute gain at Microsoft being almost the same as the number of lost nginx sites, this is merely a coincidence — only 1.2 million nginx sites actually switched to using IIS this month (0.8 million of which opted for IIS 6.0), whereas 1.4 million switched to Apache. 23 million nginx sites that were present in last month's survey have since expired, including a large number of .ru domains previously hosted by Hetzner Online.
nginx enjoyed better fortunes amongst the million busiest sites, where it extended its market share by 0.22 percentage points to 15.31%, placing it 2.46 points ahead of Microsoft. File sharing site rapidshare.com has recently started displaying an nginx Server header; previously the site did not reveal which server software it was running, and New Zealand Post has switched from Apache to nginx.
Google's market share went up to 4.81% this month (+0.36) after gaining 3.6 million sites, and could be set to grow even further now that the Google App Engine PHP runtime is widely available. In January, 244 million sites were using PHP (mostly on Apache), highlighting the strong demand. Once a PHP application has been deployed on App Engine, it can make direct use of Google Cloud Storage through existing PHP filesystem functions such as
Google is specifically targeting WordPress users to migrate to App Engine — Google have produced an App Engine plugin for WordPress to allow it to interact with App Engine-specific services such as mail and storage. Google cites motherboard.vice.com as one of the early adopters of the App Engine PHP runtime, having moved from nginx running on Amazon EC2. Vice's in-house content management system is powered by the Yii PHP framework, and was moved fully over to App Engine during a limited preview period.

In the October 2013 survey we received responses from 767,234,152 sites, an increase of 28.2M.
Apache experienced another significant loss, 1.8M hostnames, and saw its market share drop to 45% — the lowest it has been for over 15 years. The last time Apache's market share stood at 45% was in January 1998, at which time it served 830k hostnames. Despite gaining 18M new sites this month, 16M sites previously served by Apache no longer exist and a further 4M sites have moved to other web servers, including 1.5M sites to nginx and 420k sites to Microsoft. This loss was also seen in the SSL survey in which Apache lost 5.8k sites, but it continues to be the largest web server with 43% of the SSL market.
Microsoft saw the largest growth, gaining a net 16.5M hostnames. In May, it seemed inevitable that nginx would shortly match Microsoft in the number of sites served — there was just a single percentage point separating them. Microsoft’s growth has since accelerated however, and Microsoft now stand almost 5 percentage points above nginx. The next version of Microsoft's web server, IIS/8.5, has now been released to MSDN and TechNet subscribers ahead of the public release on the 18th October. More than 600 sites are already served by IIS/8.5, up 60% over last month.
Nginx gained 11.4M hostnames overall this month. Included in this was a net gain of 1.5M hostnames from Apache and a net loss of 340k hostnames to Microsoft. Among the top million, nginx gained 4.4k hostnames and the server is used by 15% of the top million sites.
All major server vendors suffered losses in the active sites metric resulting in a net decrease of 780k active sites, 664k of which belongs to Apache. In June 2000, when Netcraft started measuring active sites, 44% of sites were deemed active. The gap between the number of hostnames and active sites has been steadily increasing, and now the number of active sites account for less than a quarter of all sites.
ICANN signed 30 registry agreements for new top level domains in September. New gTLDs added this month include .reviews and .technology. General availability for domain registration of new gTLDs will begin in early 2014. The last new TLD to be seen in the wild is .post, a sponsored TLD first seen in October 2012. There were just 4 .post domains seen in the survey this month.
