This month's most reliable hosting company is Datapipe. Datapipe was ranked first last month, and has now been in the top ten for 11 of the last 12 months. Datapipe offers managed hosting and IT services from six data centers distributed across the globe and has recently started to offer managed cloud hosting through a product called the Datapipe Managed Cloud. This new service is backed by Amazon Web Services, and Datapipe say it's the "first Managed Services Provider of significant scale and size to offer Amazon Web Services to enterprise clients in a comprehensive, all-inclusive managed services program."

In second and third place this month are Swishmail, which offers managed email and web hosting, and New York Internet which offers various services, including dedicated servers, colocation and web hosting. Swishmail and New York Internet also frequently appear in Netcraft's top ten most reliable hosting company sites.

This month, the three most reliable hosting company sites are being served by FreeBSD. Of the remaining seven sites, six run Linux and one runs Windows Server 2003.

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.
