In July 2021, dinahosting had the most reliable hosting company site: it responded to all of Netcraft’s requests, with an average connection time of 75ms. dinahosting has appeared in the top 10 table five times in 2021 so far and offers its services from Interxion and Global Switch in Madrid. Customers can choose from a range of cloud and managed solutions as well as register domain names.

Bigstep, Webair and ServerStack appear in second, third and fourth places respectively. These sites responded to the same number of requests and were separated by average connection time. Bigstep’s bare metal cloud hosting provides the flexibility of cloud hosting without the associated overhead and performance reductions of virtualization. The bare metal offerings are available in data centres in the UK and Romania. Webair offers managed and private cloud services, storage and backup solutions from its eight facilities in New York, Chicago, Los Angeles, Montreal, London, Paris, Amsterdam and Singapore. ServerStack provides managed and dedicated solutions from its three data centres in North America and Amsterdam.

Nine of the top 10 hosting company sites used Linux in July, continuing the dominance of Linux in the top 10.

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.
