Rackspace had the most reliable hosting company site in June 2021, and has come either first or second in the ranking for six consecutive months. The top four sites each had no failed requests, but an average connection time of 9ms gives Rackspace the edge. Rackspace offers a variety of cloud hosting solutions from 40 data centres across Europe, North and South America, Asia and Australia.

In second place this month, Bigstep had an average connection time of 62ms. Bigstep offers “bare metal” cloud hosting, to provide the flexibility of cloud hosting without the associated overhead and performance reductions of virtualization.

Hyve Managed Hosting and Pair Networks round out the top four in June. Hyve is a fully managed UK-based hosting provider, with facilities in 35 locations around the world.

The most popular choice of operating system continues to be Linux, used by 9 of the top 10 hosting company sites. FreeBSD also made an appearance, used by NYI.

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.
