One.com had the most reliable hosting company website in December 2017, successfully responding to all requests made by Netcraft. This is their third time claiming the top spot in 2017, with a total of nine appearances in the top ten in 2017. Founded in 2002, One.com has since established a global presence with offices in eleven countries around the world and services offered in fourteen languages.

Swishmail also responded to all of Netcraft's requests, but came in second due to a slightly slower average connect time. Swishmail made six appearances in the top ten in 2017, including a first place ranking in August. Swishmail offers business email solutions in a variety of plans, all of which come with a 30 day unconditional guarantee.

Hyve Managed Hosting had the most appearances in the top ten in 2017. They placed every month except January, and are currently on an impressive eleven-month streak. Hyve's site has had a 100% uptime record since Netcraft started monitoring it in 2016.

Linux is the most popular choice of operating system this month with seven of the top-ten hosting companies using it. FreeBSD is second most popular with three appearances.

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.

Both Webair and Swishmail responded to all of our requests in November 2017, but the faster average connect time for Webair means it takes the top spot. Webair is a US-based provider of fully managed hosting solutions and has appeared in the top ten a total of seven times in 2017, also taking the top spot in May. Swishmail, a provider of email and web hosting solutions using FreeBSD, has appeared in the top ten five times in 2017.

The six websites ranking third to eighth each failed to respond to only a single request in November. vXtream and Hyve (in third and fourth places) have both made their tenth appearances in the top ten in 2017 - vXtream was absent only in March, while Hyve narrowly missed out by ranking 11th in January. London based vXtream recently acquired Qube Managed Services contracts and infrastructure including presence in datacentres in London, New York and Zurich. Hyve places fourth with an average connect time of 68ms, 2ms slower than vXtream, it offers fully managed cloud hosting from datacentres in the UK, US and China.

Pair Networks owns its own datacentre in Pittsburgh and also offers space in the datacentre of a partner in Denver, it is one of the three websites in the top ten to be run on FreeBSD.

Linux is once again the most prevalent operating system in use for the top ten websites, with seven of the ten websites using it. FreeBSD is the operating system of choice for the remaining three.

ViaWest had the most reliable hosting company website in October 2017, successfully responding to all of Netcraft's requests with an average connect time of just 5 milliseconds. This is ViaWest's third appearance in the top-ten this year, and its first time in the number-one spot. ViaWest was acquired by Peak 10 Inc. in August, and now operates as the combined company Peak 10 + ViaWest. It boasts 40 data centers connected by a 100 Gigabit core network backbone.

vXtream and Hyve came in second and third respectively. Both sites successfully responded to all of Netcraft's requests, but vXtream clinched second place with a marginally quicker average connect time of 58 milliseconds. Both companies are on a top-ten streak: vXtream appearing every month since April, and Hyve appearing every month since February.

ServerStack and Rackspace also had no failed requests this month, placing fourth and fifth based on their average connect time. ServerStack's site has had a 100% uptime record over the past two years, and has appeared in Netcraft's monthly most reliable hosting company sites more than 40 times since 2012. Serverstack operates three data centers across the US and Europe, and offers a 100% uptime SLA.

Linux remains the most popular choice of operating system, with eight of this month's top-ten hosting companies using it. F5 and SmartOS also make an appearance.

One.com had the most reliable hosting company website in September 2017, successfully responding to all requests made by Netcraft. One.com, which offers a number of shared hosting packages to clients, has offices across Europe, the USA, and Asia. September is One.com's second month at the top of the chart in 2017, with six appearances in the top ten this year.

Second place was achieved by vXtream, which recently completed its acquisition of Qube Managed Services. vXtream's site successfully responded to all requests made by Netcraft, but with a marginally slower average connect time than One.com. vXtream offers managed hosting, colocation, and cloud-based solutions from data centres in Zurich, London and New York. vXtream has spent eleven of the last twelve months in the top ten, taking the top spot four times.

EveryCity also saw no failed requests, but placed third due to a slightly slower average connect time than vXtream. EveryCity's site has had a 100% uptime record since March 2016, and is making its third appearance in the top ten over the last four months. EveryCity specialises in managed cloud hosting and is based in London.

Linux continues its dominance of the top ten, with seven websites in the list using the operating system. FreeBSD and SmartOS make one appearance each.

Swishmail had the most reliable hosting company website in August 2017. It responded to all of Netcraft's requests from several points around the internet, with not a single failure, and an average connect time of 57.6 milliseconds. The US-based company provides email and web hosting services based on FreeBSD, and this is its fourth appearance in the top ten so far this year.

There was an incredibly close battle for first place this month, as Qube Managed Services also managed to respond to all of Netcraft's requests, but its average connect time was fractionally longer at 57.7 milliseconds – less than 0.2 milliseconds slower than Swishmail's average. This puts Qube in second place, but only just. Impressively, this is Qube's seventh time in the top ten for 2017. It operates data centres in London, Zurich and New York, where it offers managed hosting, colocation, and cloud-based solutions.

In third place, with a single failed request, was One.com. Its average connect time was noticeably faster than those of Swishmail and Qube; but reliability trumps speed in this contest. This is One.com's fifth top-ten appearance this year, including another first place ranking in April. Founded in 2002, the company was established in Denmark, and offers a variety of internet services including 1-click WordPress installations, domain registrations, email hosting, and Office 365.

Five of this month's top-ten hosting companies used the Linux operating system for their main sites during August, while two used FreeBSD, one used SmartOS, and another used an F5 device. Conspicuous by its absence is Windows, which has not appeared in the top ten since January, despite being found on more than half of the 1.8 billion websites in our Web Server Survey.

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.

Qube Managed Services takes July 2017's top position for most reliable hosting company site, with its site successfully responding to all requests. Qube operates from three data centres — in the City of London, Zurich, and Manhattan, New York - offering managed hosting, colocation, and cloud-based solutions.

Memset's site also successfully responded to all requests in July, as it did in June. However, its average TCP connect time was less than a millisecond slower than Qube's, granting Memset second place in July. Memset is a UK-based hosting company with a 99.998% uptime over 3 years, and 100% uptime over the past 6 months.

New York Internet gained third place with only one failed request. New York Internet is the only hosting provider in July's top 10 list to use a non-Linux operating system to power its website, being powered instead by FreeBSD.

Hyve Managed Hosting continues its top 10 streak, now having been in the top 10 for six consecutive months.

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.
