Qube had the most reliable hosting company site in May, with only one failed request. London-based Qube has performed remarkably well so far this year, fitting in with its vision to be the most reliable and trusted managed hosting company in the industry. As well as coming first three times so far this year, Qube also narrowly missed out on another first place in January.
With only three failed requests, Datapipe had the second most reliable hosting company site in May. Datapipe has also performed well this year, achieving first place results in both January and March; so far this year, only Qube and Datapipe have achieved first place. Over the past eight years, Datapipe has racked up an impressive 100% uptime record, and 99.994% since Netcraft started monitoring its website in June 2003 (downtime is only recorded when all of Netcraft’s performance monitors simultaneously record an outage).
In third place, with four failed requests, was EveryCity, which has only been monitored by Netcraft since April. EveryCity started more than six years ago and its offices have been based near London’s Tower Bridge ever since. Its primary datacenter is powered by 100% renewable energy and it offers various products and services, including public and private cloud hosting, dedicated servers, domain names, SSL certificate management, disaster recovery and content delivery.
The Linux operating system was used by seven of May’s top ten hosting company websites, while two used FreeBSD. www.everycity.co.uk runs on SmartOS, which combines the ZFS file system, DTrace dynamic tracing, kernel-based virtual machines and Solaris Zones operating system-level virtualisation into a single operating system based on a community fork of OpenSolaris.
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.
