Choopa.com had the most reliable hosting company site in April 2021, heading the table for the fifth time in the past 12 months. The top five sites each responded to all of Netcraft’s requests, but Choopa.com’s average connection time of just 3ms wins it the top spot. The host offers a range of services including cloud hosting, dedicated hosting and colocation in its own primary facility in Piscataway, New Jersey as well as other facilities in Los Angeles, Amsterdam, and Tokyo.

Second place this month goes to Rackspace, narrowly behind Choopa.com with an average connection time of 6ms. Rackspace has appeared in the top 10 for five consecutive months, four of which placed it in the top three. Rackspace provides a wide variety of cloud services from its global network of over 50 locations across five continents.

dinahosting completes the top three for April. dinahosting offers its services from Interxion, in Madrid, and customers can choose from a range of cloud and managed solutions as well as register domain names. Swishmail and Flexential also responded to all of Netcraft’s requests in April, and appear in 4th and 5th place.

Linux remains the dominant choice of operating system among the top 10 in April, being used by nine of the top 10 sites. FreeBSD also makes an appearance at 6th place with 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.
