Hyve Managed Hosting had the most reliable hosting company site in June, successfully responding to all of Netcraft's requests. This is Hyve's fifth consecutive top ten placement, and marks the first time it has clinched the number-one spot. The company recently announced that it is now a part of the G-Cloud 9 framework agreement which simplifies cloud technology procurement for the UK public sector. As well having its primary data centre in the UK, Hyve also has data centres in New Jersey, San Jose, Hong Kong, and Shanghai.

Memset’s site came in second place in June, also with no failed requests, but with a marginally slower average connection time. The UK-based company has had an uptime of 99.998% over the last three years. Its customers have included British government agencies such as the Home Office, Her Majesty's Revenue & Customs and the Cabinet Office.

Netcetera’s site also successfully responded to all of Netcraft's requests and took third place. This is the company's fourth top ten placement in Netcraft's rankings for 2017. Netcetera is based on the Isle of Man and provides data centre colocation, cloud hosting, dedicated servers and managed web hosting services.

Hivelocity came in fourth, also with no failed requests, but with a slightly slower average connection time than the companies in June 2017's top three. This is the company's second consecutive month with 100% response rate to Netcraft's queries.

Linux has once again dominated as the most commonly used operating system amongst the top ten hosting company websites, the only exceptions being EveryCity (SmartOS) and Pair Networks (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.

Four hosting companies responded successfully to all of Netcraft's requests during May: Webair, Swishmail, ServerStack and Hivelocity.

Webair had the lowest average connection time out of the four, and so took first place in May’s rankings. This is the first time the cloud hosting company's site has topped Netcraft's Most Reliable Hosting Company Sites ranking, but marks its fourth consecutive month in the top ten. Webair recently announced a partnership with Microsoft to offer Azure ExpressRoute, which creates a direct network connection between Webair and the Microsoft Cloud.

Swishmail's site has retained its second place position in Netcraft's ranking from April. Similarly to last month, Swishmail narrowly missed out on the top spot based on its average connection time despite having as many successful requests. The US-based company provides FreeBSD-based email and web hosting services.

ServerStack came in third, with a slightly longer average connection time than both Webair and Swishmail's site, but still no failed requests. ServerStack offers fully managed services which include software installation, proactive monitoring, automated backups, performance optimisation, troubleshooting, and virtualisation.

Hivelocity came fourth after responding successfully to all of Netcraft's requests. The hosting provider has three US-based data centres: two in Tampa, Florida and a third one in Atlanta.

Linux continues to be the predominantly used operating system, powering eight of the top ten sites. The only exceptions are Swishmail and Pair Networks which both run FreeBSD.

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.

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.
