In July 2019 Rackspace had the most reliable hosting company site, with no failed requests and an average connection time of 5ms. Rackspace offers a range of managed dedicated and cloud hosting solutions from data centres in North and South America, Europe, Asia and Australasia. In the past six months, Rackspace has had the most reliable hosting company site three times and been in the top 10 each month.

Bigstep, ServerStack and Pair Networks complete the top four, each responding to all of Netcraft's requests in July. These companies are therefore ranked by their average connection time. Bigstep offers "bare metal" cloud hosting to provide the flexibility of cloud hosting but without the associated overhead and performance reductions of virtualization.

The six sites that complete the top 10 each failed to respond to a single request by Netcraft in July. GoDaddy came in fifth place with the fastest average connection time among all monitored providers of 4ms.

SmartOS and FreeBSD each make an appearance in the top 10 but Linux continues to dominate, powering eight of the top 10 sites in July.

Netcraft measures and makes available the response times of around twenty 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.
