The top four hosting companies had the same number of failed requests this month and they are therefore ranked by average connection time.
With a 99.9% uptime guarantee, Netcetera are June's most reliable hosting company as they had the fastest average connection time of the four. Based in the Isle of Man, Netcetera have customers in over 60 countries worldwide and offer a wide range of services including co-location, cloud, virtual and email hosting, domain registrations and e-commerce. They last made it into the top 10 in February 2012 when they ranked fifth.
Very close behind Netcetera came Swishmail and New York Internet - both based in New York City, who ranked second and third place, whilst ReliableServers.com based in New Jersey, USA came fourth. Though they had the same number of failed requests, their average connection times were 22ms, 26ms and 30ms slower respectively than Netcetera's. Swishmail and ReliableServers.com have attained a top ten rank for the fourth time this year and New York Internet for the third time.
FreeBSD and Linux are the dominant choice of operating system for the most reliable hosting companies, with Netcetera the exception in running Windows Server 2008.
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.
