Each of the top three hosting companies had only one failed request this month and they are therefore ranked by average connection time.
Top of the table this month is Datapipe, which offers a range of services including managed hosting, compliance, security and cloud computing. Datapipe is committed to customer service and offers a 100% network uptime guarantee.
The second most reliable hosting company in June was INetU, which offers dedicated managed hosting services from data centers with resilient networks, backup power and strong physical and network security. InetU also offers compliance and consultancy services to customers around the world.
Third this month was New York Internet. NYI offers colocation, dedicated servers and virtual hosting from data centers in New York. The company focuses on reliability and technical support that is responsive round the clock.
Half of the sites in the top ten in June were running Linux, four were running FreeBSD, and one was running 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.
