Returning to the top spot for the fourth time this year was Datapipe, without a single failed request, and an average connection time of just 0.012 seconds. Datapipe has managed to feature in the top ten for seven out of eight months so far this year and has maintained a 100% uptime record over the past ten years. In July, Datapipe announced an expansion of its presence in Europe with the opening of a new data centre in Moscow, becoming its 21st data centre worldwide.

In second place with just two failed requests was EveryCity, ranking in the top ten for a third consecutive month, and making its fourth appearance in the top ten this year. Based in London, EveryCity specialises in managed cloud hosting, and has maintained a 100% uptime over the last 6 months.

Third place this month goes to Qube Managed Services, who narrowly beat CWCS with the same number of failed requests but faster connection time. Placing in the top ten for the third month in a row, Qube has data centres in London, New York, and Zurich, offering cloud services, managed services, and colocation.

Linux continues to be the predominantly used operating system, powering six of the top ten company sites. However for the first time since June 2015, one of the top 10 was running on Windows.

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.

XILO Communications Ltd has moved up the table to become the most reliable hosting company site in July, with only two failed requests. This is the sixth time this year that XILO has appeared in the top ten, including two second places. XILO offers services from shared hosting to dedicated servers and operates from the UK.

Second place for July went to Hyve Managed Hosting, with only three failed requests and an average connect time of 0.059 seconds. Also based in the UK, Hyve Managed Hosting offers a wide range of cloud based hosting solutions, and has recently become a hosting partner for the Kentico CMS.

Third place was taken by EveryCity, with a marginally slower average connect time than Hyve of 0.063 seconds. This is the second time that EveryCity has made it into the top ten since its ISO27001 accreditation in March, and its 2-year uptime now stands at 99.998%.

After measurement from multiple geographical locations, UK-based organisations took the top four spots for July. The absence of Windows operating systems from the top ten has also continued, with the last appearance being in June 2015.

Datapipe had the most reliable hosting company site in April, responding to all of Netcraft's requests. Datapipe's performance has seen it appear in the top ten every month so far in 2016, continuing a streak which has placed the company in the top ten 11 times in the past 12 months. Datapipe provides hosting services out of a number of data centres in Europe, Asia and North America. In April, Datapipe announced that it would be partnering with Singapore's largest electronics retailer to ensure the scalability of the latter's online infrastructure.

Qube had the second most reliable hosting company site. As with Datapipe, Qube's site responded to all of Netcraft's requests, but was fractionally slower to do so. Qube's performance is also consistent: the company has appeared in the top ten 9 times over the last 12 months.

CWCS achieved third place in April, also with a 100% response rate, albeit with an average connect time that was marginally slower than both Datapipe and Qube's. CWCS provides shared and managed hosting solutions, with data centre facilities in England and North America, and counts organisations such as KPMG and the University of York amongst its clients.

Linux is once again the most popular choice of operating system with hosting companies: eight out of the top ten companies in April hosted their websites on Linux machines.
