Netcetera had the most reliable hosting company website in May 2018, being the only site to successfully respond to all of Netcraft's requests. Netcetera provides carbon-neutral hosting solutions from its data centre in the Isle of Man, and has managed to maintain a 99.98% uptime over the last 10 years.
There were three hosting company websites with only one failed request in May. Out of these, One.com had the fastest average connection time of 60ms, granting it second place. Founded in 2002, the company was established in Denmark, and offers a variety of internet services including a no-code website builder, 1-click WordPress installations, domain registrations, email hosting, and Office 365. Third place was very close, with ServerStack claiming the position with an average connection time of 93.5ms—just half a millisecond faster than Pair Networks in fourth place. ServerStack has maintained an impressive 99.98% uptime since Netcraft started monitoring its website 5 years ago.
ViaWest, Rackspace, and Choopa all had very fast average connection times of around 9ms, but only achieved 5th, 6th, and 7th place respectively due to each having failed to respond to two or three requests.
Linux was the operating system of choice on 8 out of the top 10 most reliable hosting company sites in May, with FreeBSD and SmartOS each making a single appearance.
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.
