GoDaddy had the most reliable hosting company site in June 2019; it responded to all of Netcraft’s requests with an average connection time of just 4ms. GoDaddy provides a wide range of hosting and domain registration services, including its widely used website builder software, which provides customers with a simple way to create a web presence.

The next seven most reliable sites also responded to all of our requests, and are separated in the ranking by their average connection time. This puts Rackspace in a close second place, with an average time of 5ms. This is the fifth consecutive month with Rackspace placing in the top 10, topping the list twice in that time. Rackspace offers a range of managed dedicated and cloud hosting solutions.

Webair came third this month, following an appearance at the top of the chart in May. Webair provides a range of services including managed hosting solutions and high performance cloud environments.

Linux continues to be the dominant choice of operating system among the top 10, powering nine of the ten sites this month. SmartOS also makes an appearance at 4th place.

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.

Information on the measurement process and current measurements is available.
