Swishmail and iWeb are the most reliable hosting company sites for December 2007, closely followed by DataPipe, 3FN and Go Daddy.

Swishmail's US-hosted website is powered by FreeBSD, Apache and PHP and they offer a variety of professional and enterprise web hosting plans in addition to email hosting. iWeb's site is hosted in Canada, offering dedicated, shared and colocation hosting as well as domain registration services.

DataPipe appears in third place in December, marking its 11th appearance in the top ten during 2007 - an impressive feat. November was the only month where DataPipe did not reach the top ten. 3FN makes a forth place appearance in December, falling from 3rd place in November, while Go Daddy appears in 5th place.

Only two of December's top ten hosters run Linux, including iWeb, while four run FreeBSD. Two of the hosters run Windows Server 2003, while another uses Windows 2000.

Netcraft measures and makes available the response times of fifty 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.

Further information on the measurement process and current measurements are available.
