Datapipe had the most reliable hosting company site in June, with only two isolated failed requests. This is Datapipe's third victory so far this year, and the company also achieved second place in May. Datapipe has accrued an outstanding 100% uptime record over the past eight years, and consistently exhibits very fast connections times, regularly being one of the fastest sites we monitor. The only other hosting company to have reached first place this year is Qube who did so three times, equalling Datapipe.

Netcetera came second in June, also with only two failed requests, giving it the most reliable Windows-based hosting company site. Netcetera has been in the hosting business since 1996 and offers a 99.9% uptime guarantee, although in practice its site actually reached 99.99% uptime over the past year and 99.96% over nine years.

Pair Networks had the third most reliable hosting company site in June. Like Datapipe, their website is served using FreeBSD. As well as hosting websites, Pair Networks recently hosted a Girl Develop It workshop in Pittsburgh, which is where their own custom-built data centres reside.

Netcetera had the only Windows-based hosting company site to appear in the top ten in June, while three sites used FreeBSD and the remaining six used Linux. Downtime is only recorded when all of Netcraft's performance monitors simultaneously record an outage, hence why it is still possible to achieve 100% uptime even if a site fails to respond to an individual performance monitor.

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.

Qube had the most reliable hosting company site in May, with only one failed request. London-based Qube has performed remarkably well so far this year, fitting in with its vision to be the most reliable and trusted managed hosting company in the industry. As well as coming first three times so far this year, Qube also narrowly missed out on another first place in January.

With only three failed requests, Datapipe had the second most reliable hosting company site in May. Datapipe has also performed well this year, achieving first place results in both January and March; so far this year, only Qube and Datapipe have achieved first place. Over the past eight years, Datapipe has racked up an impressive 100% uptime record, and 99.994% since Netcraft started monitoring its website in June 2003 (downtime is only recorded when all of Netcraft's performance monitors simultaneously record an outage).

In third place, with four failed requests, was EveryCity, which has only been monitored by Netcraft since April. EveryCity started more than six years ago and its offices have been based near London's Tower Bridge ever since. Its primary datacenter is powered by 100% renewable energy and it offers various products and services, including public and private cloud hosting, dedicated servers, domain names, SSL certificate management, disaster recovery and content delivery.

The Linux operating system was used by seven of May's top ten hosting company websites, while two used FreeBSD. www.everycity.co.uk runs on SmartOS, which combines the ZFS file system, DTrace dynamic tracing, kernel-based virtual machines and Solaris Zones operating system-level virtualisation into a single operating system based on a community fork of OpenSolaris.

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.

is.gd goes down, takes a billion shortened URLs with it

The popular is.gd URL shortening service has been offline for more than two days, taking with it more than a billion shortened URLs. Shortly before the site disappeared on Sunday, the homepage reported that its links have been accessed nearly 50 billion times.

The shortened links generated are usually not more than 18 characters long, including the protocol http://. These links are commonly used in tweets, emails, and text messages where long URLs are impractical. Despite the fact the shortened links do not work, many previously-created is.gd shortened URLs are still appearing on Twitter.

is.gd is owned by and supported by UK hosting provider Memset, who planned to support it as a free service indefinitely. Notably, its sister site, v.gd, is still up and running. Other free services provided by Memset include TweetDownload, TweetDelete and the statistics calculator Tweetails.

For security reasons, both is.gd and v.gd disallow the shortening of URLs which use the data: and javascript: protocols. Nevertheless, the service is still abused by fraudsters who use the shortened URLs to direct victims to phishing sites. Some fraudsters have appended a query string to the shortened URL in an attempt to make it look similar to those used by the phishing target. For example, the following is.gd URL was used to redirect victims to a Taobao phishing site:

http://is.gd/Tb###U?2.taobao.com/item.htm?spm=2007.1000337

Throughout April, is.gd was the fifth phishiest URL shortening service. By far the phishiest was tinyurl.com, which pointed to 17 times as many phishing sites, making it account for 60% of all phishing activity amongst the top five URL shortening services. Privately-held bit.ly, Google's goo.gl and GoDaddy's x.co also pointed to more phishing sites than is.gd.

Three years ago, the is.gd service suffered a shorter outage of a few hours. This was caused by the failure of some of the virtual machines in its frontend cloud, which were responsible for accepting HTTP requests from a load balancer.

Update 21/05/2014: is.gd is now back online. An explanation for the outage can be found at http://is.gd/news.php

Qube had the most reliable hosting company site in April, with only one failed request. The London-based managed hosting provider uses data centres in the UK, USA and Switzerland, all of which are ISO 27001 certified. This information security management system standard uses a three-stage external audit process to ensure the company has suitable security policies and risk treatment plans.

Qube (which stands for "Qualified By Experience") has performed rather well so far this year — it also had the most reliable hosting company site in February (with no failed requests), narrowly missed out on first place in January, and made 4th place in March. Qube provides a Virtual Data Centre cloud computing service powered by VMware vCloud, managed dedicated servers, and managed colocation in its Tier 3 central London data centre.

Host Europe had the second most reliable hosting company site in April, with three isolated failed requests from Netcraft's globally distributed performance collectors. The company has attained 100% uptime over the past six months, and 99.98% uptime over 12 months. The Host Europe Group also owns the largest domain name provider in the UK, 123-reg, which recently teamed up with Knowhow to offer domain and website building packages from Currys and PC World stores.

XILO Communications came third in April, with four failed requests. Its uptime over the past 12 months is an impressive 99.993%. Netcetera, New York Internet, and ServerStack also had only four failed requests, but with longer average connection times than XILO.

Half of April's top ten hosting company websites were served from Linux machines, including all of the top three. Four of the other sites used FreeBSD, and one used Windows Server 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.

Managed services provider Datapipe had the most reliable hosting company site in March, closely followed by Choopa in second place. Both of the top two hosting company sites experienced three failed requests, and therefore the tie for first place was broken by analysing average connection times. Datapipe had the lowest average connection time within the top ten of 18ms and therefore ranked in first place.

Datapipe has a 100% uptime record which now stretches back over eight years; its last outage occurred back in March 2006. Over this time Datapipe's infrastructure has proved it can withstand the brutal forces of nature, surviving several hurricanes, typhoons and a snow storm. Along with 100% uptime, Datapipe has a low proportion of failed requests which has led to them ranking in first place many times over the years.

Second-place Choopa is based in a data centre in Piscataway, New Jersey and additionally has infrastructure in Los Angeles, Amsterdam, and Tokyo. Choopa describes its infrastructure's architecture as redundant with no single point of failure, and has backed this up with a 100% Uptime SLA plus a 0% Packet Loss Guarantee within its network. Choopa offers IPv6 throughout its entire network using a dual stack approach — avoiding the need to tunnel over IPv4. Recently Choopa has launched its own SSD VPS service via a new brand Vultr.

In third place with four failed requests is ReliableServers which lists reliability as its number 1 policy. ReliableServers is based in New Jersey and purchases server racks and network bandwidth from Choopa in Piscataway which hooks its servers directly into Choopa's network. ReliableServers offers Dedicated hosting with a 100% uptime guarantee.

Elsewhere in the table Webzilla made its first appearance in the top ten, which may be a result of its recent infrastructure upgrades. Webzilla launched in 2005 and offers a range of hosting services including dedicated, cloud, colocation and CDN.

Linux powers almost all the hosting company sites in the top 10. The exceptions are FreeBSD running Datapipe's site in first place and Windows Server 2012 running Netcetera's site in ninth place.

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.

London-based Qube Managed Services had February's most reliable hosting company site, www.qubenet.co.uk, which successfully responded to all requests sent. This is the second time in six months Qube has had no failed requests, having also achieved it back in September. Qube's reliability is perhaps due to the routing infrastructure it has in place at its data centres in London, New York and Zurich. Qube's carriers include Level 3 Communications and Zayo (formerly AboveNet), both of which are known for their extensive network coverage across Europe and America.

In second place is ServerStack with two failed requests. ServerStack has maintained a 100% uptime record over the past year and offers a 100% uptime service-level agreement from its data centres in Amsterdam, New Jersey and San Jose. ServerStack uses the nginx web server to serve its website and also some of world's busiest websites, including a site which serves 150 million pageviews per day.

In third place with four failed requests is Hosting 4 Less. Hosting 4 Less has a 99.9% uptime guarantee and has been providing web hosting services for over 15 years. It owns and operates a Californian data centre facility which is privately peered via multiple gigabit connections to the Internet backbone.

FreeBSD powered the sites for both Datapipe (lowest connection time within the top 10) and Pair Networks. Windows Server 2012 powered Server Intellect and the remaining seven sites ran Linux, including first place Qube.

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.
