Four of the hosting companies sampled this month experienced no failed requests at all to their websites, and these four are therefore ranked by average connection time. Top of the table is Datapipe, which has been in the top ten in ten of the last twelve months, and in the top three seven times in the same period. The company offers a variety of services including colocation, cloud computing and hosted servers from datacentres in the U.S., the U.K. and China.
Second this month is iWeb Technologies, which has also appeared in the top ten regularly over the last year. iWeb have been offering hosting services for over ten years with a range of products which includes shared web hosting, managed hosting and dedicated servers.
www.codero.com ranked third this month. The company is a relative newcomer to the hosting industry, having begun life as a division of aplus.net in July 2009. It now offers dedicated and managed hosting services aimed specifically at small businesses.
In terms of operating system, the top ten hosting companies are evenly split between Linux and FreeBSD this month with four of each and one company running F5 Big-IP.
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.
