May 1st - 31st 2005
Hostway and Energis share the top slot as as the most reliable hosting companies site this month, followed by Go Daddy, Datapipe, INetU and France Telecom. Hostway, which is based in Chicago and has operations in six countries, was also the most reliable hoster in April 2005. Energis provides connectivity to Netcraft, but has no particular advantage over any other hosting company site in the performance analysis, as none of the performance data collection machines are on the Energis network.
Notably half of this month's top 10 are running Windows. Recent months have seen a real mixture of operating systems in use on the most reliable sites, in contrast to the early months when FreeBSD dominated the upper end of the table.
Netcraft measures and makes available the response times of fifty leading hosting providers' sites. The performance measurements are made at fifteen minute intervals from eight separate points around the internet, and averages are calculated over the immediately preceding 24 hour period.
From a customers’ point of view, the percentage of failed requests is more pertinent than outages on the 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.
Fuller information on the measurement process and current measurements are available.
