Datapipe was the most reliable hosting company in November and has now claimed the top spot seven times this year. The company offers a range of services including managed hosting, compliance, security and cloud computing. Datapipe recently extended its presence in Asia by partnering with Shanghai Data Solutions (SDS), which owns and operates fully redundant carrier-neutral datacentres in China.

The second most reliable this month was Qube Managed Services, a London-based hosting company with additional datacentres in New York and Zurich. The company offers managed hosting, cloud hosting and managed colocation for a range of customers with a particular interest for those in the Finance and New Media sectors. This is the second time that Qube has ranked in the top three. The company was also listed as best performing cloud platform in Europe and the US this month.

Hosting 4 Less came in third this month. The company guarantees a 99.9% uptime and offers Windows and Linux hosting as well as e-commerce and FTP hosting. Hosting 4 Less also sells SSL Certificates through Certs 4 Less, a sibling company which is a Platinum Partner of VeriSign, GeoTrust, Thawte and RapidSSL.

Six of November's top ten most reliable hosting company sites used Linux, while three used FreeBSD and one used 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.
