Montreal based iWeb was the most reliable hosting company in October 2013 with only two failed requests. Two days ago the US IT-infrastructure company Internap announced plans to buy iWeb in a deal worth $145m. Both companies provide IaaS and are corporate sponsors of the OpenStack foundation. Internap has data centres around the world which will allow iWeb to expand on its four data centres, all based in Canada.

Hosting 4 Less was the second most reliable hosting company; it also only had two failed requests but its slower average connection time was used as the decider. 2nd place is its highest ranking this year, having also been ranked 2nd in September 2012. Qube Managed Services, who regularly feature in the top 10, ranked third this month having been the most reliable hosting company in September.

UK2 celebrated their 15th year in business this month and are again the fourth most reliable hosting company. UK2 cater to a wide range of customers, from individuals and small businesses wanting to create an online presence with their Website Builder tool to larger websites using its Xen based Virtual Servers and dedicated hosting.

Linux is used by eight of the top ten with the remaining two, Swishmail and Pair Networks using FreeBSD. Netcetera was the most reliable Windows hosting company again this month - although just outside the top 10 in 12th place. 8 of the top 10 are using the Apache web server including the top four companies.

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 Managed Services had the most reliable hosting company site in September 2013, with not a single failed request throughout the whole month, and an average connection time of only 0.066 seconds. Qube is based in London, but they also host services from data centers in New York and Zurich. Their New York data center is at 111 8th Avenue, which is adjacent to a trunk dark fiber line. This building is the city's third largest in terms of floor area and was bought by Google for $1.9 billion in 2010. Qube provides managed and colocated hosting services from each of its data centers, as well as virtual data centers based on VMware vCloud Director.

Including September, Qube ("Qualified By Experience") has made five appearances within the top ten so far this year, and also attained another first place result in May.

In second place, with just one failed request, was Kattare Internet Services. It is among the most reliable sites monitored by Netcraft, managing 99.993% uptime over the past year and 99.97% over the past seven years. On September 21st, it was predicted that a damaging storm would hit the Pacific Northwest (Kattare's base of operations), causing thunder and wind storms, with 50mph gusts strong enough to take down trees. The next day this storm took out Kattare's power supply; however, the use of generators meant there were no outages recorded during the storm.

Hosting 4 Less narrowly missed out on second place, as although it only had one failed request during September, its average connection time was 3 milliseconds slower than Kattare's.

Seven of September's top ten hosting company sites were running on Linux operating systems. Five of these (including Qube, Kattare and Hosting 4 Less) used the Apache web server software, while ServerStack and krystal.co.uk used nginx.

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.

Multacom had the most reliable hosting company site in August 2013, with no failed requests and an average connection time of 0.105s. Multacom operates out of two secure data centres in Los Angeles, and focuses on providing shared and dedicated hosting services.

In second and third place were Hyve Managed Hosting and Bigstep. Both sites had only two failed requests, but Hyve's slightly shorter time to connect gave it the edge over Bigstep. Hyve provides managed hosting options from data centres across America, as well as in Shangai, Hong Kong, and London. Hyve also handles hosting for several major international firms, including British Airways, Tesco and Nokia. Bigstep, which provides hosting services for "big data" companies, continues to maintain its impressive record since Netcraft started monitoring its performance, with a consistent 100% uptime over 5 months.

For the first time since May, hosting companies running Windows Server ranked in the top ten: Netcetera's website runs on Windows Server 2012, INetU use Windows Server 2003 and Server Intellect use Windows Server 2008. The most reliable hosting company site, Multacom, runs FreeBSD (as does last month's most reliable site, Swishmail). All other sites in the top ten run on 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.

Swishmail had the most reliable hosting company site in July 2013. The New York based company failed to respond to only one of Netcraft's requests during the whole month, and had an average connection time of 0.076s. Swishmail primarily operates as an email hosting provider and uses three different data centers, run by Savvis, Level3 and Globix in New York City. Upstream connectivity is provided by Level3, Savvis, Cogent, AboveNet and Globix.

In second and third place, both also with only one failed request, were ServerStack and iWeb. ServerStack had the most reliable hosting company site during the previous month, and has data centers in New Jersey, San Jose and Amsterdam. iWeb's data centers in Montreal have a total dedicated server capacity of nearly 35,000.

For the second month in a row, none of July's top ten hosting companies were running on Windows operating systems. The most reliable hosting company site, Swishmail, was running on FreeBSD, as were two others sites within the top ten; the remaining seven were running on Linux. In terms of web server software, Apache was used by seven of the top ten sites, while nginx was used by three sites, including Swishmail's.

ServerStack had the most reliable hosting company site in June, with only two failed requests. ServerStack provides managed dedicated hosting from data centres in New Jersey, San Jose, and Amsterdam, and counts amongst its clients high-traffic sites such as MTV and academic publisher Elsevier. Over the eight months Netcraft has been monitoring ServerStack's performance, it has appeared in the top 10 five times and been the most reliable hosting company site twice.

Codero and Swishmail took second and third place respectively. Both companies had 100% uptime and just two failed requests separate the top three companies. Both Codero and Swishmail are based in the United States: Codero has a presence in Virginia, Illinois and Arizona, whilst Swishmail operates out of three New York data centres.

Bigstep, which focuses on providing hosting infrastructure for big data companies, started being monitored three months ago and has maintained a 100% uptime record thus far.

For the first time since May 2012, none of the companies in the top 10 Most Reliable Hosting Company Sites were running a version of Windows Server. ServerStack runs Linux, as do seven other hosting companies in the top 10. FreeBSD is used by the remaining two: Datapipe and Swishmail.

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.

Qube Managed Services had the most reliable hosting company site in May, with only 2 failed requests. Qube specialises in providing managed hosting from three data centres in London, New York and Zurich. Qube was founded in 2001 and provides services to a number of notable clients, including Betfair (a large betting exchange) and blinkbox (a video streaming service from Tesco in the UK). Qube has appeared in the top 10 over twenty times since Netcraft began monitoring it in March 2010 and has now ranked in 1st place four times.

Datapipe and ServerStack placed 2nd and 3rd, both narrowly missing the top spot by a single failed request. Datapipe had the lowest average connection time out of all the top 10 sites, which breaks the tie with ServerStack in its favour. Datapipe has continued to maintain its 100% uptime record having recently passed the 100% uptime over 7 years milestone despite some of its nine data centres being in the path of hurricanes, typhoons, and a snowstorm. Serverstack has now been monitored by Netcraft for seven months and has already appeared in the top 10 four times. The company's 100% uptime SLA offers 5% credit for every half hour of sustained unscheduled downtime.

All but three of May's top 10 most reliable hosting companies hosted their own sites on Linux, including Qube in 1st place, ServerStack in 3rd place and Bigstep in 4th place, which made its debut entry in the table last month. FreeBSD is used by 2nd place Datapipe and last month's winner Swishmail (this month in 8th place). INetU was the only hosting company in the top 10 to host its site on 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.
