Netcetera had the most reliable hosting company site in February, successfully responding to all of Netcraft’s requests. Netcetera has maintained an uptime of 99.994% over the last year, and 99.96% over the last 12 years. The company is based on the Isle of Man and provides carbon-neutral shared, dedicated, and cloud hosting.

Qube Managed Services took second place with only a single failed request. This is Qube's fifth consecutive month in the top two positions of the most reliable hosting company websites table. Qube recently partnered with Level 3 to provide a new DDoS protection service.

In third place is Krystal Hosting Ltd, which successfully responded to all but three of Netcraft's requests. The UK-based company offers 100% SSD cloud VPS and hosting.

Nine of February's ten most reliable hosting company sites were running Linux, with Swishmail being the only company which uses FreeBSD. Swishmail came in seventh with five failed requests. Swishmail, Webair and CWCS all successfully responded to the same amount of Netcraft's requests, so their average connection times were used to determine the ranking between them.

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.

Qube Managed Services started the year in first place after responding successfully to all of Netcraft’s requests made during January 2017. This UK-based managed hosting provider has had one of the top ten most reliable hosting company websites ten times in the past 12 months, including three times at number one.

In second place is CWCS, which successfully responded to all but one of Netcraft's requests. CWCS narrowly beat Netcetera, with the same number of failed requests but with a faster average connection time of 0.072 seconds. CWCS is a UK-based managed hosting provider with data centres in Nottingham, London and Manchester, with additional facilities available in Dallas, Miami and Toronto.

Netcetera took third place, also with only one failed request, with an average connection time of 0.076 seconds. Netcetera, which is based on the Isle of Man, has been in the top ten for eight of the past 12 months, and five of these occasions saw it make its way into the top three.

Seven of the top ten most reliable hosting company sites in January 2017 were running Linux, with the remainder using FreeBSD, Windows Server 2012 and SmartOS.

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.

Netcetera rounded off the year by having the most reliable hosting company site in December 2016, successfully responding to all but one of Netcraft's requests. In 2016, Netcetera made eight appearances in the top ten, reaching second place in February, March and June. Earlier in 2016, Netcetera celebrated 20 years of successful business, thanking its clients, including some that have been with the company since the day it opened.

Netcetera is based on the Isle of Man, a self-governing territory of the United Kingdom known for its low-tax economy. Netcetera's data centre, The Dataport, uses several energy-saving technologies including Free Air Cooling and virtualisation, which when coupled with carbon offsetting, make it a zero carbon data centre. This carbon-neutral approach is estimated to have saved more than two million kilograms of CO2 to date.

Qube Managed Services took second place in December, with five failed requests. Qube also fared well over the course of 2016, with December marking its tenth appearance in the top ten, including two times at the top of the table, in March and October. Qube uses data centres in London, New York and Zurich to provide its cloud, colocation and managed services; and like Netcetera's website, Qube's is served from a Linux machine.

XILO Communications Ltd came third, also with five failed requests, but with a slower average connection time than Qube. XILO uses enterprise-class Dell hardware for its shared, reseller and cloud hosting services, and also made ten appearances in the top ten during 2016, which included a first place in July. Like Qube, XILO is headquartered in the UK and uses Linux to host its own website.

Seven of December's top ten most reliable hosting company sites were served from Linux machines, including Anexia's, which also had only five failed requests. The remainder used Windows Server 2012, FreeBSD and SmartOS. Linux was the most common operating system used amongst the top ten hosting provider sites over the course of 2016, with two months having a top ten that consisting entirely of Linux-powered websites.

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.

Datapipe had the most reliable hosting company site in November, successfully responding to all requests. Datapipe has been in the top ten for ten months in 2016 and has a 100% uptime record over the last ten years. Datapipe was named as the top Cloud Service Provider for 2016 by Talkin’ Cloud in their 2016 Cloud 100 Research report.

Qube Managed Services took second place also with no failed requests, but a slower average connection time than Datapipe. Qube has been in the top ten for nine months this year, including last month when they topped the list. Qube has data centres in London, New York, and Zurich, offering cloud services, managed services, and colocation.

CWCS came in third place with only one failed request in November, narrowly beating Anexia which also had one failed request, but a slightly slower average connection time. CWCS was awarded PCI DSS Level 1 Service Provider Status in August for its primary data centre in Nottingham.

Linux is again the predominantly used operating system, powering seven of the top ten company sites. EveryCity continues to be the only provider in the top 10 that uses SmartOS.

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 October, successfully responding to every request we made during the month. Qube has been in the top ten for eight months so far this year. Qube recently selected Epsilon to deliver its CloudLX connectivity platform, which will offer its customers direct access to on-demand Ethernet services.

One.com took second place in October with just two failed requests. This managed hosting provider was recently awarded Editor's Choice by Netzsieger's 2016 hosting comparison for its product coverage, performance, security, and support.

Hyve Managed Hosting came in third place with just three failed requests in October. This UK-based hosting provider specialises in mission-critical hosting, which is reflected in their 100% uptime since we started monitoring www.hyve.com in July. Fourth-place ServerStack and fifth-place CWCS also had three failed requests in October, with the tie being broken using the average connect time.

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.

Datapipe retained the top spot in September, successfully responding to all but three requests. Datapipe has been in the top ten for eight of the last nine months and has a 100% uptime record over the last ten years. In August, Datapipe announced its acquisition of UK managed cloud services provider Adapt, a move intended to further strengthen its European presence.

Memset took second place with four failed requests. Memset was the UK's first accredited carbon-neutral web host. In July, Memset won the Best Dedicated Hosting Award at the ISPA Awards for the second year running. The judges were impressed by Memset's response times, technical support, carbon neutrality, and by Memset having adopted IPv6 as standard.

In third place with five failed requests is Krystal, a UK-based hosting provider boasting 100% SSD hosting.
