Qube Managed Services was the most reliable hosting company in September, responding to 99.997% of all requests throughout the month. The London-based company specialises in VMware cloud services, colocation, backups, and also offers PCI-DSS compliant hosting on both virtual and dedicated platforms. Qube also has infrastructure in Zurich and New York, and was also the most reliable hosting company during August.
Hosting 4 Less was the second most reliable hosting company, responding to the same percentage of requests, but with a longer average connection time. Hosting 4 Less has been operating since 1998 and offers both dedicated and shared hosting on Linux or Windows platforms, all backed by a 99.9% uptime guarantee.
Linux was the most prevalent operating system amongst the 10 most reliable hosting companies in September; seven of these sites were hosted on Linux servers, including www.qubenet.net and www.hosting4less.com, while two used FreeBSD and one used 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.
