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. 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.

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.

Aptly named ReliableServers.com was the most reliable hosting company site in March, responding to all but one of Netcraft's requests throughout the month. The company's servers are located in seismically sound data centers in Newark and North Bergen, New Jersey, with 24/7 on-site support staff and diesel generators. Connectivity is provided by multiple fiber routes from Nlayer, Tiscali, Tinet, Level3, and extensive private peering in the NY Metro area.

In second place, with only two failed requests, was last month's winner Codero. Their dedicated servers include a 100% uptime guarantee and are hosted in Codero's own data centers in Phoenix, Arizona, Chicago and Illinois.

Linux was used by five of the most reliable hosting company sites in March, including both ReliableServers.com and Codero. Three used FreeBSD, while the remaining two were running 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. In the event the number of failed requests are equal then sites are ranked by average connection times.

INetU took second place for the second consecutive month, having regularly appeared in the top 10 over the last year. The company offers managed and cloud hosting from its data centres in Pennsylvania, Virginia and the Netherlands.

The Spanish company DinaHosting took third place this month, with virtual, dedicated and cloud service offerings, as well as server colocation.

Half of this month's 10 most reliable hosting companies use Linux, with slightly less than half running Windows Server, and one provider using FreeBSD.
