In October 2018, GoDaddy had the most reliable hosting company site, with a single failed request and the fastest average connection time of 5ms. GoDaddy's site has now appeared in the top 10 six times so far in 2018, and has topped the rankings three times in 2018. The Website Builder tool offered by GoDaddy is widely used, as seen in Netcraft's September Web Server Survey, and provides customers with a simple way to create a web presence.
Swishmail, Netcetera and dinahosting ranked second, third and fourth place, with their sites also only experiencing a single failed request. The tie is broken by their average connection times: 84ms, 85ms and 91ms. Swishmail is a provider of a range of email and web hosting services and returns to the top 10 for the 7th time in 2018.
Following in fifth and sixth place are vXtream Ltd and One.com, whose sites both failed to respond to two requests. Rackspace had the second fastest average connection time of 6ms but appears 7th in October due to 3 failed requests. Like GoDaddy, Rackspace has appeared in Netcraft's top 10 most reliable hosting company sites six times in 2018.
Linux continues to dominate the web server market as the most popular operating system and this is reflected in 9 of the top 10 hosting company sites being served by web-servers running Linux. FreeBSD also makes an appearance in second place.
Netcraft measures and makes available the response times of around thirty 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.
