One.com had the most reliable hosting company website in September 2017, successfully responding to all requests made by Netcraft. One.com, which offers a number of shared hosting packages to clients, has offices across Europe, the USA, and Asia. September is One.com's second month at the top of the chart in 2017, with six appearances in the top ten this year.

Second place was achieved by vXtream, which recently completed its acquisition of Qube Managed Services. vXtream's site successfully responded to all requests made by Netcraft, but with a marginally slower average connect time than One.com. vXtream offers managed hosting, colocation, and cloud-based solutions from data centres in Zurich, London and New York. vXtream has spent eleven of the last twelve months in the top ten, taking the top spot four times.

EveryCity also saw no failed requests, but placed third due to a slightly slower average connect time than vXtream. EveryCity's site has had a 100% uptime record since March 2016, and is making its third appearance in the top ten over the last four months. EveryCity specialises in managed cloud hosting and is based in London.

Linux continues its dominance of the top ten, with seven websites in the list using the operating system. FreeBSD and SmartOS make one appearance each.

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.
