1. Amazon Web Services’ growth unrelenting

    In September 2012 Netcraft reported that Amazon had become the largest hosting company in the world based on the number of web-facing computers. In the last eight months, the e-commerce company's tally of web-facing computers has grown by more than a third, reaching 158k. The number of websites hosted on these computers has also increased, from 6.8M in September 2012 to 11.6M in May 2013, a 71% increase.

    Although Amazon’s main business is still online retail, Amazon Web Services (AWS), its cloud computing division, has been growing in significance. In Amazon's first quarter of 2013 the Other category (which still includes AWS along with other non-retail activity) was just under 5.0% of its revenue, up from 3.2% at the same point in 2011. The first publicly available AWS service was launched in 2004, but it was not until 2006 that Amazon launched its two core services S3 (data storage) and EC2 (per-hour rental of virtual computer instances). Since then, Amazon has been increasing the number of services provided: in 2012 alone, 159 new services and features were released.

    Including its retail infrastructure, the number of web-facing computers at Amazon has grown more than thirty-fold in four years: in May 2009, Netcraft found 4,600 Amazon-controlled web-facing computers; in May 2013, Netcraft found 158k web-facing computers on 164k IP addresses. Netcraft estimates the number of computers behind a group of IP addresses by using a variety of heuristics based on the TCP/IP characteristics seen in the HTTP responses gathered. Hosted on those computers, there are more than 11.6M websites (or hostnames) which corresponds to 2.1M websites with unique content (active sites). Despite being the largest hosting provider by number of web-facing computers, it is dwarfed by Go Daddy, the largest hosting provider when considering the number of websites hosted. Go Daddy has 37M websites on just 23k web-facing computers: the high ratio of websites to web-facing computers may be indicative of Go Daddy's role as a registrar, for which it has a large network of holding pages, and its inexpensive shared hosting platform.

    EC2 - Elastic Compute Cloud

    EC2, provides on-demand virtual-computer instances billed per hour and is currently available from all nine AWS regions. Each region may correspond to multiple physical data centres which are structured into "Availability Zones". The two largest regions, US East (Northern Virginia) and EU West (Ireland), account for more than three-quarters of all EC2 usage as measured by Netcraft. Sydney, the newest AWS region, now accounts for just under 1% of all measured web-facing computers using AWS, having almost tripled in size in the past four months. In total, more than 156k instances power at least one hostname on 3M domains across the internet.

    Launched in 2011, the GovCloud (US) region is specifically intended for more sensitive applications that require additional security and compliance with US regulations. As of May 2013, Netcraft found just 27 web-facing computers within the government cloud, some of which power www.grdregistry.org and www.govdashboard.com. Given its intended role, it would not be surprising if a large proportion of the computers used in the region are not web-facing.

    Notable EC2 users include Netflix, a DVD rental and video streaming service, Instagram, a photo sharing application now owned by Facebook, and DuckDuckGo, a search engine.

    Metric (EC2 Total) February 2013 March 2013 April 2013 May 2013 Growth (4 month)
    Web-facing Computers/Instances 141,960 145,648 152,041 156,225 10%
    IP Addresses 144,625 148,837 155,712 160,884 11.2%
    Domains 2,788,685 2,810,906 2,996,147 3,061,178 9.8%
    Hostnames 9,489,496 9,938,480 10,649,545 10,925,661 15.1%

    Many uses of EC2 such as batch data-processing will not be directly measurably over the internet: Netcraft measures publicly visible computers with corresponding DNS entries and which respond to HTTP requests. Netcraft's Web Server Survey is run at Amazon from the Northern Virginia region, so the region may be over-reported due to services like latency based multi region routing which provide differing responses depending on topological location.

    S3 - Simple Storage Service

    S3 provides an online file storage service which can be managed programmatically via Amazon's API. Files are logically grouped into containers called buckets which can be made public and accessible over HTTP but default to being private. As with EC2, Netcraft cannot track private use of S3 but is able to survey websites using S3 publicly to serve static files and even entire websites.

    Metric (S3 Total) February 2013 March 2013 April 2013 May 2013 Growth (4 month)
    Domains 41,782 42,561 45,721 48,636 16.4%
    Hostnames 124,454 127,370 132,962 138,588 11.4%

    In May 2013, a total of 139k hostnames were found to be hosted directly on S3, either using a subdomain of s3.amazonaws.com or using a custom CNAME pointing to S3. Of these, 24.7k hostnames, or over 18.5k domains, point to an S3 bucket configured to serve an entire website, as does mediahackers.org. Many more websites are not hosted entirely on S3, but make use of the service to serve static files such as images, stylesheets, or file downloads.

    One of the most widely referenced S3 hostnames is used for twitter badges bucket, which was once a common method to display twitter icons on a third-party website. Tumblr, a popular blogging platform recently acquired by Yahoo!, also makes use of S3 to host static media.

    CloudFront

    CloudFront is a Content Delivery Network which can be used to serve both dynamic and static content from 28 edge locations which are topologically closer to a site's visitors. Caching content reduces the bandwidth and performance requirements on the website's own servers and, by being topologically close to visitors, the latency associated with each HTTP request can be improved.

    In the May 2013 survey, more than 63k hostnames were served via CloudFront, more than 60% of which point to an S3 bucket. Amazon uses CloudFront on its own websites, including imdb.com, and also uses it for serving images on Amazon.com. Other than Amazon itself, CloudFront users include: the Toronto Star, a Canadian newspaper, and Pirifrom, the makers of utility program CCleaner, are two of the most visited sites using CloudFront amongst users of the Netcraft Toolbar.

    Metric (CloudFront Total) February 2013 March 2013 April 2013 May 2013 Growth (4 month)
    Domains 22,920 24,079 25,264 26,221 14.4%
    Hostnames 55,578 57,817 60,475 63,203 13.7%

    The number of CloudFront-dedicated IP addresses and computers cannot be easily measured as different results are obtained depending on the location of the request.

    Route 53

    Route 53, is a managed Domain Name System (DNS) hosting service. Route 53, named for the TCP and UDP port used for the protocol, hosts DNS records which map from human-readable hostnames to IP addresses. Integrated with the rest of AWS, it allows programmatic access to change DNS records in response to changes elsewhere in a customer's infrastructure. As with CloudFront, Amazon have servers providing this service in edge locations outside of its 9 EC2 regions; Route 53 is available from 28 separate locations.


    Metric (Route 53 Total) February 2013 March 2013 April 2013 May 2013 Growth (4 month)
    Domains 136,698 146,635 161,619 169,111 23.7%
    Hostnames 3,493,986 3,662,195 3,831,910 4,068,053 16.4%

    Over the past four months there has been a steady growth in the number of websites using Route 53 to host their DNS records: it now serves DNS records for 169k domains. Busy sites making use of this service include pinterest.com, a social photo-sharing website which is a heavy user of Amazon's infrastructure; MediaFire, a file uploading and sharing service; and ow.ly a URL shortener.

    Heroku

    Heroku is Platform as a Service (PaaS) provider owned by Salesforce. Whilst not operated by Amazon, it makes heavy use of AWS services, especially EC2. Heroku provides an abstracted managed environment for web developers to deploy applications in a number of different languages. In May 2013, Heroku was serving 70K domains directly (not behind a CDN) across 4,786 computers.

    Popular sites using Heroku include www.upworthy.com, a curated news website; help.github.com, a knowledge base for the popular git-based project hosting service; and Absolventa, a German job market.


    Metric (Heroku total) April 2013 May 2013 Growth (2 month)
    Computers 4,293 4,786 11.5%
    IP Addresses 4,408 4,972 12.8%
    Domains 65,821 69,781 6%
    Hostnames 1,094,578 1,102,663 0.7%

    Heroku, as demonstrated in the results from Netcraft's survey, has been available almost exclusively from the Northern Virginia EC2 region. In April, Heroku announced availability of its service in Europe from the AWS EU West region based in Ireland. Only a limited number of Heroku customers have had access to this region during a private beta phase which explains the currently low uptake: only 1% of the computers attributed to Heroku were in the region.


    IP Addresses April 2013 May 2013
    US East (Northern Virginia) 4,374 4,915
    EU West (Ireland) 33 56

    Summary

    The launch of the new AWS region, hundreds of new services, new partnerships, and multiple price reductions, are a clear indicator of the relentless growth of Amazon Web Services.

    Swishmail had the most reliable hosting company site in April 2013, with no failed requests. Swishmail has a presence in three New York data centres which proved to be resilient when Swishmail stayed online in October whilst being hit by Hurricane Sandy, despite New York being in the centre of much of the damage. Swishmail offers a variety of managed web hosting plans in addition to its core service of enterprise-grade email hosting. Swishmail has been monitored by Netcraft since April 2007.

    In second place is INetU which also had no failed requests, but it missed the top spot by just 11ms due to using the average connect time as the tie-breaker. INetU offers dedicated managed hosting services and cloud hosting services from ten data centres in the US and Europe including a new data centre in Seattle. Netcraft has been monitoring INetU since June 2003.

    iWeb is in third place again following last month's success, it narrowly missed second place by having a single failed request. iWeb is based in Montréal where it has four data centres.

    Newcomers Bigstep and Midphase have made their debut top 10 entries, after being monitored for one month and six months respectively. Hyve placed 8th this month, its third appearance since Netcraft began monitoring it in November having maintained 100% uptime over 5 months.

    Swishmail, April's most reliable hosting company, runs its site on FreeBSD. Two other sites in this month's top ten are running FreeBSD – Datapipe, which was top last month and has an impressive 100% uptime over 7 years, and Pair Networks. Both INetU in second place, and Server Intellect in fourth place, are running Windows Server 2008. The remaining five – including iWeb in third place – use Linux.

    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.

    The Online Certificate Status Protocol (OCSP) is an alternative method to Certificate Revocation Lists (CRLs) for obtaining the revocation status of an individual SSL certificate. Fast and reliable OCSP responders are essential for both Certificate Authorities (CAs) and their customers — a slow OCSP response will introduce an additional delay before many browsers can start sending and receiving encrypted traffic over an HTTPS connection.

    Starfield Technologies, a Go Daddy brand, had the most reliable OCSP responder last month with only a single failed request and an average connection time of 24ms. Starfield Technologies was founded in 2003 as the technology research branch of Go Daddy. Go Daddy customers have the option to choose which issuing organization to use when buying an SSL certificate. Although both Go Daddy and Starfield appear to share the same OCSP responder infrastructure, ocsp.godaddy.com had five failed requests, however this was still fewer than StartCom, Symantec, and Trend Micro. Both Go Daddy and Starfield issue certificates in all three certificate assurance categories: Domain Validation (DV), Organisation Validation (OV), and Extended Validation (EV). Starfield is most prominent in the EV sector — more than 15% of all EV certificates issued within the group are issued by Starfield — but it remains only a small part of Go Daddy's SSL certificate business: Starfield accounts for just 10% of certificates issued.

    StartCom had the shortest average connect time (11ms) of all monitored CAs last month after having moved its OCSP infrastructure at the end of February. StartCom, as well as Entrust, now delivers its OCSP responses via the Akamai CDN (Content Delivery Network), reducing the OCSP connection overhead to a minimum by serving content from as topologically close as possible to the client. GlobalSign is a CloudFlare evangelist, using CloudFlare's CDN platform for its OCSP and CRL infrastructure as well as their own corporate website.

    Many of the monitored OCSP responders are served by Citrix Netscaler devices. Citrix Netscaler is a hardware appliance that provides, amongst other features, load balancing and firewall functions. The use of such load balancing technology is no surprise — a single certificate on a popular site that does not use OCSP stapling could generate a significant number of OCSP requests, causing a CA's responder to experience high volumes of traffic.

    In many circumstances each connection to an HTTPS site could trigger multiple OCSP requests: a request for the server's certificate and one for each intermediate certificate. OCSP responses are typically valid for a week, so some caching is possible. Caching can reduce both the burden on OCSP responders and increase the perceived performance of HTTPS websites to users, but is limited to repeat visits. OCSP Stapling is designed to improve performance by allowing the web site's server to “staple” the OCSP response to the TLS handshake, removing the need for the client to connect to the CA's OCSP responder.

    Netcraft measures and makes available the OCSP and CRL end point response times of all the major Certificate Authorities (CAs). 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.

    Datapipe was the most reliable hosting company in March 2013, with both the fastest average connection time and no failed requests. Even more impressive is its remarkable 100% uptime record, which now stretches back for more than 7 years, and its connection times are regularly among the fastest we see each month.

    The second most reliable hosting company in March 2013 – also with no failed requests – was ServerStack. Since Netcraft started monitoring ServerStack in October 2012, their site has had an uptime record of 99.990%. The company's 100% uptime SLA offers 5% credit for every half hour of sustained downtime, although this excludes periods of scheduled maintenance and its only outage so far lasted just 24 minutes.

    iWeb ranked third after failing to respond to only one request during the whole of March. This performance was closely followed by Go Daddy and Server Intellect, each of which also failed to respond to just one request, but demonstrated marginally slower connection times than iWeb. Go Daddy's appearance in fourth place came despite a series of distributed denial of service (DDoS) attacks against its European webhosting operations, based in the Netherlands, which caused some of its customers' websites to become temporarily unavailable.

    The previous month's winner, Hyve Managed Hosting, ranked eighth this time with three failed requests, but demonstrated very good average connection and total response times. These metrics are purportedly taken into account by Google's search algorithms, resulting in better rankings. Hyve's customers can gain similar advantages by using its high speed cloud platform with "light-speed" disk access, which allow its virtual servers to outperform traditional dedicated servers.

    Datapipe runs its website on FreeBSD, which was also used by two other top-ten hosting companies during March: Swishmail and Pair Networks. Two sites were using Windows Server 2008, while the remaining five – including ServerStack – used Linux.

    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.

    In its third month being publicly monitored by Netcraft, Hyve Managed Hosting had an almost perfect record: only two requests failed out of the 30,000 requests we made in February. www.hyve.co.uk is served by nginx, a web server well-known for its performance. Hyve's primary data centre is in Global Switch London 2, a well-located modern facility in London's Docklands, close to key business centres. Hyve specialise in Cloud, Dedicated, and Secure FTP hosting, with clients including British Airways, Tesco, and American Express.

    Kattare Internet Services also had just two failed requests in February, but was ranked in second place by using the average connect time as the tie-breaker. Kattare — a Java specialist based in Oregon — has been monitored by Netcraft since October 2003. Kattare, named for Kättare (Swedish for "heretic"), is a keen advocate of open-source solutions including FreeBSD and Linux: more than 97% of the web-facing computers found at the hosting company are powered by Linux.

    Netcetera, up from 8th place in January to 3rd in February, is the only hosting company with a site hosted on Windows in the top 10: the remainder, where known, are all powered by Linux or FreeBSD. Netcetera has data centres in London and the Isle of Man, a jurisdiction which welcomes online gambling, linked by a comprehensive network.

    Datapipe, Hosting 4 Less, XILO, and Hostway Romania all had seven failed requests, split only by average connect time: Datapipe's impressive connect time, 16ms, is evidence of the benefits of their globally disperse hosting platform. February was only the second month where Hostway.ro has been in the top 10, only three months after their first appearance in the top 10 in November 2012.

    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.

    Datapipe had the most reliable website of all monitored hosting providers, responding to every single request made by Netcraft from its 11 monitoring points distributed across North America and Europe. Datapipe.net achieves such rapid average connection times — meaning that it often wins the top spot even when otherwise tied on failed requests — by serving content from the server topologically closest to the client. Datapipe's Stratosphere platform is available in five global data centres allowing its clients to benefit from similar performance.

    Qube, ranked second this month, also with an exemplary record, with no failed requests recorded but a slightly longer average connection time. Qube has a number of notable clients, including both BetFair, an online gambling exchange, and blinkbox, a video streaming service in the UK, which trust it to provide a dependable network from its three data centres in London, New York, and Zurich.

    UK2.net finished in third place, having just a single failed request. One of UK2.net's flagship brands, VPS.net, released a newly redesigned website and logo on the last day in January. At the same time, UK2.net also announced a set of new promises for VPS.net customers including a 99.9% SLA for unmanaged customers and 100% for those with managed services.

    Server Intellect are joined in the top ten this month by a fellow Windows-based hosting provider, Netcetera, appearing in the top ten for the 57th time, but the first time since September 2012.
