ViaWest had the most reliable hosting company website in October 2017, successfully responding to all of Netcraft's requests with an average connect time of just 5 milliseconds. This is ViaWest's third appearance in the top-ten this year, and its first time in the number-one spot. ViaWest was acquired by Peak 10 Inc. in August, and now operates as the combined company Peak 10 + ViaWest. It boasts 40 data centers connected by a 100 Gigabit core network backbone.

vXtream and Hyve came in second and third respectively. Both sites successfully responded to all of Netcraft's requests, but vXtream clinched second place with a marginally quicker average connect time of 58 milliseconds. Both companies are on a top-ten streak: vXtream appearing every month since April, and Hyve appearing every month since February.

ServerStack and Rackspace also had no failed requests this month, placing fourth and fifth based on their average connect time. ServerStack's site has had a 100% uptime record over the past two years, and has appeared in Netcraft's monthly most reliable hosting company sites more than 40 times since 2012. Serverstack operates three data centers across the US and Europe, and offers a 100% uptime SLA.

Linux remains the most popular choice of operating system, with eight of this month's top-ten hosting companies using it. F5 and SmartOS also make an 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.
