Qube Managed Services had the most reliable website during June, responding successfully to all of Netcraft’s requests. This is Qube’s fourth appearance in the top ten in 2015, continuing its strong showing from 2014 when it placed in the top ten in eleven months, and came first on four occasions. Qube is based in London and offers managed private cloud hosting services from datacentres in London, New York and Zurich.
In second place, ServerStack also successfully responded to all requests in June, placing second only as a result of a slightly slower average connection time. ServerStack provides managed hosting services to enterprises from three datacentres in Amsterdam, New Jersey and San Jose. It has appeared in the top 10 list frequently in the past few years.
Linux remains the most popular choice of operating system, with 9 of the top 10 companies using the OS to power their website, while the remaining one uses Windows Server 2012.
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.
Information on the measurement process and current measurements is available.
