One.com comes in first place in April, up from seventh place in March. One.com responded to all but one of Netcraft's requests, with an average TCP connection time of 40 milliseconds. The company was founded in 2002 and is based in Denmark, with staff also based in Dubai and India.

Swishmail and Hyve follow in second and third places respectively. These hosting company sites also responded successfully to all but one request, but had marginally slower average connection times than One.com's site. Swishmail is based in the United States and provides business email and web hosting services, whilst Hyve is based in the United Kingdom and provides a variety of cloud and dedicated server hosting services. Hyve reached the finals of the 2017 European IT and Software Excellence Awards under both the Managed Service Solution of the Year and Service Provider of the Year categories.

Xilo has consistently featured in the top 10 so far in 2017. Xilo provides a variety of services, ranging from shared hosting up to managed and self-managed dedicated servers, as well as domain name services and SSL certificates.

Of the top 10 hosting providers for April, all but one of their websites are running on Linux, with the exception being Swishmail's, which runs on FreeBSD.

Netcraft measures and makes available the response times of around thirty 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.

Netcetera had the most reliable hosting company site in March 2017, retaining its first place spot from February. Netcetera's site once again successfully responded to all of Netcraft's requests, with an average TCP connection time of 63 milliseconds. This continues Netcetera's strong performance from the past year: its site has placed in the top ten in eight out of the past twelve months, including three first places.

Memset, Webair, and Kattare's sites each had two failed requests this month, placing their sites second, third and fourth based on average connection times. Memset is a UK-based provider of dedicated and cloud hosting services, operating data centres near London and another in the US West-Coast area. Webair is a New York-based hosting provider which offers fully managed cloud and infrastructure solutions, with data centres in New York, Los Angeles, Montréal and Amsterdam. This is Webair's second consecutive appearance in the top ten in 2017.

Anexia, Xilo, and Netcetera have consistently placed in the top ten so far in 2017. All three serve their company sites from Linux machines, and this remains the most common operating system used amongst the other top ten hosting companies' sites. In March, nine out of ten of the most reliable hosting companies' websites were powered by Linux, with the remaining one, operated by Kattare, using Citrix Netscaler.

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.

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.

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.

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.

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.
