Rackspace had the most reliable hosting company site in March 2019. This is the second month in a row, and the third time in the last 12 months, that Rackspace has topped the ranking. Rackspace offers a range of managed dedicated and cloud hosting solutions.
The top five hosting company sites each responded to all of Netcraft's requests in March; to break the tie they are ranked by average connection times. This puts New York Internet in second place. NYI offers bare metal, cloud and colocation services in its US datacentres. One.com took third place, appearing in the top 10 for a second consecutive month. One.com offers a variety of internet services including a no-code website builder, 1-click WordPress installations, domain registrations and email hosting.
Linux is used by seven of the top 10 in March and remains the most popular choice of operating system, with the remaining three sites all powered by FreeBSD.
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.
