Both of the top two hosting companies had the same number of failed requests this month and they are therefore ranked by average connection time.
After slipping to third last month, the top spot was regained by Datapipe in August. They offer a range of services including managed hosting, compliance, security and cloud computing. Datapipe have recently expanded their UK datacenters.
In second place this month is iWeb Technologies, a Canadian hosting company based in Montreal. iWeb Technologies provide web hosting, dedicated servers, managed hosting and colocation to customers from around the world. They have recently launched a new product range, Smart Servers, which aim to give the benefits of both virtualization in the cloud and dedicated hardware.
Swishmail come in at third place this month, who offer a variety of managed web hosting plans in addition to their core service of enterprise-grade email hosting.
For the first time this year, FreeBSD has the largest share of hosting providers in the top 10 with half of them running FreeBSD servers. Of the other hosting providers in the top 10, 4 run Linux and 1 uses 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.
