EveryCity had the most reliable website during May 2015, responding to all but two of Netcraft’s requests. Since Netcraft began monitoring its site in April 2014, EveryCity has maintained a 100% uptime record. Besides SmartOS-based hosting, EveryCity also specialises in Solaris hosting on both SPARC and Intel platforms.
In second place is Datapipe, with just four failed requests to its website during May 2015. Two other companies had the same number of failures: Anexia and CWCS. Datapipe’s impressively quick average connection time (0.012 seconds) gives it the edge in the tie-breaker, fending off both Anexia (0.088 seconds) and CWCS (0.104 seconds). Datapipe has data centres in key technology and financial hubs including New York, Silicon Valley, London, and Hong Kong.
Anexia (3rd place) and CWCS (4th place), both with four failed requests and both of which are based in Europe, differ in their focus: Anexia operates 58 data centres across the world, whereas CWCS concentrates on the UK market, owning two "state of the art" British data centres. Anexia announced in early May that it had become an official Debian mirror, providing support to the open-source project.
Making it into the top 10 for the first time since its monitoring began in February 2015, Umbee Hosting’s website responded to all but a handful of Netcraft’s requests. Umbee Hosting has five data centres, spread across three continents: two in the London region, two in metro New York, and one in Sydney.
Linux remains a popular choice amongst the top 10 hosting company websites, powering six. The use of SmartOS and FreeBSD brings up the total of UNIX-based operating systems to eight. The remaining two are powered by Windows Server 2008 and 2012.
Netcraft measures and makes available the response times of around forty 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.
