July 2012 Web Server Survey

In the July 2012 survey we received responses from 665,916,461 sites, a decrease of 31M since last month.

This drop comes as a result of the loss of a large number of wildcard hostnames with similar content at AmeriNOC (-30M), Axoft Group (-10M), and Tailor Made Servers (-8M). All of these sites were running Apache, resulting in a decrease of 39M hostnames running on Apache and dropping its market share slightly to 61%. All other web server vendors gained hostnames this month, with the biggest increase being 1.5M hostnames running on Microsoft IIS. This was followed by nginx and lighttpd with increases of 950k and 800k hostnames respectively.

Within Netcraft’s million busiest websites, nginx experienced a jump in market share this month to 12.5% after an increase of 22k sites. Nginx also saw the biggest switch of hostnames, with about.com changing around 600 top-million hostnames from Apache, the most popular of these being pcsupport.about.com. Nginx now stands nearly 1 percentage point of market share behind Microsoft. Apache and Microsoft both saw losses within the top million, of 32k and 10k respectively.

The most reliable hosting company during May was CWCS — a UK-based company offering a variety of web and managed hosting services from their own data centres in Nottingham. Advertising a "100% uptime guarantee" CWCS top the chart for May after responding to all but one request.

ReliableServers.com remains in the top ten for the third month in a row, placing second — 6 places higher than last month. Offering dedicated hosting and colocation from their two New Jersey data centres — located in Newark and North Bergen — ReliableServers.com also guarantees 100% uptime.

Seeing their highest placing this year, iWeb Technologies are May's third most reliable hosting company. Their four data centres in the Montréal area are supplied by 7 different network providers to ensure high reliability.

During May nine out of the ten most reliable companies were using Linux servers with the remaining company, Datapipe, last month's most reliable company, running FreeBSD.

Netcraft measures and makes available the response times of around forty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

From a customer's point of view, the percentage of failed requests is more pertinent than outages on hosting companies' own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage. In the event the number of failed requests are equal then sites are ranked by average connection times.

Information on the measurement process and current measurements is available.

June 2012 Web Server Survey

In the June 2012 survey we received responses from 697,089,482 sites, a growth of 5.1% or 34M sites since last month.

All major web server vendors experienced an increase in hostnames this month. After a loss of 17.5M hostnames last month Apache saw the largest growth this month with an increase of 22.8M hostnames. The second largest growth was seen by Microsoft with an increase of 3.5M hostnames. This, however, still resulted in a loss in the market share for Microsoft. nginx, after nine consecutive months of market share growth, also experienced a loss in market share albeit gaining 2.1M hostnames.

The 6th of June 2012 is the World IPv6 launch day. The event is organized by the Internet Society and it is aiming to promote the widespread usage of the protocol. This month's survey received IPv6 AAAA results for over 7M hostnames, mapping to 105k distinct IPv6 addresses. Apache was found running on the majority of these hostnames (6.2M), followed by nginx with 398k hostnames.

The most reliable hosting company for April was Datapipe, which topped the table seven times in 2011. The company offers a wide range of hosting services and has been rapidly expanding into cloud computing during the past few months. Datapipe has infrastructure spread across the globe; they have data centres in New Jersey, San Jose, Iceland, London, Shanghai, and Hong Kong. Their U.S. data centres are powered exclusively by renewable energy sources.

For the third time so far this year INetU have taken second place. INetU offers dedicated managed hosting services and cloud hosting services from data centres in both the United States and Europe.

Choopa – a New Jersey based company advertising 100% uptime and 0% packet loss guarantees – appears in third position for the second consecutive month.

Linux was used by five of the most reliable hosting companies, including Choopa; four used FreeBSD including the most reliable, Datapipe; and the second most reliable provider, INetU, used Windows Server 2008.

Netcraft measures and makes available the response times of around forty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.

From a customer's point of view, the percentage of failed requests is more pertinent than outages on hosting companies' own sites, as this gives a pointer to reliability of routing, and this is why we choose to rank our table by fewest failed requests, rather than shortest periods of outage.

May 2012 Web Server Survey

In the May 2012 survey we received responses from 662,959,946 sites, a decrease of 14M hostnames compared to last month, and the first drop we have observed in 22 months. The drop comes as a result of a loss of over 28M hostnames under the .info tld, hosted by Softlayer, on just 100 domains and 4 IP addresses. Despite this, we still observed an increase of 1.2M new domains.

nginx saw its 9th consecutive month of increased market share, gaining 894k hostnames and increasing its share to 5.48%, more than double the value it held a year ago. Apache fared the worst this month, losing 17.5M hostnames. However, it remains far ahead of the competition with two out of every three hostnames being served using Apache. We detected 654 hostnames using Microsoft-IIS/8.0 this month, the default web server in Microsoft's new Windows Server 2012, previously codenamed Windows Server 8.

Tracking of web servers using SPDY, an experimental network protocol intended to decrease web page loading times, has been added to the survey. We found a total of 339 SSL certificates used with SPDY-enabled servers. Usage outside of Google's properties is limited, though a few sites such as humblebundle.com and webtide.com support it. To operate, SPDY must be supported by both the web server and the user's browser. Of the major browsers, only Mozilla Firefox and Google Chrome have SPDY support. Apache, Jetty and Google's server software are currently the only servers that support SPDY, though nginx support is scheduled for the end of May 2012.

April 2012 Web Server Survey

In the April 2012 survey we received responses from 676,919,707 sites, giving a rise of 32.6M hostnames (5.1%) since last month.

Apache saw the largest growth (22.8M) and increased its market share to 65.5%. nginx, with the second largest growth (4.5M), increased its total to 69.9M. Microsoft had a greater increase in hostnames this month (+3.5M) compared to March, however still experienced a small loss in market share.

Microsoft's new server operating system, codenamed Windows Server 8, which was released to MSDN subscribers in September 2011 has now been made available as a public beta. Microsoft-IIS/8.0 is the default web server on Windows Server 8, and the April 2012 survey found 278 sites with this server header. However, many of these sites are running on Linux, indicating proxy servers or forged server headers. The first sites deploying Windows Server 8 include iis.net, phponwindows.net, and a Microsoft corporate remote access service. Indicative of an early beta, many installations are on isolated broadband connections, rather than at large hosting providers.
