August 1st - 31st 2007
This month's leaders include two managed hosting providers who have made frequent appearances in our ranking of the most reliable performers. New York Internet, a colocation and managed services provider in Manhattan, topped the charts for the third time this year. NYI previously was most reliable in January and May of 2007. INetU, a managed hosting provider in Allentown, Pa., was second in the July survey and has appeared in the top 10 many times, including a run of seven straight months in 2004. This is the first appearance on the reliable hoster list for Spanish hosting company Acens. In January private equity firm Nazca Capital bought a major stake in Acens, which had revenue of $18.8 million in 2006.
Close behind the top three are American discount specialists iPowerWeb and Go Daddy, who offer shared hosting accounts starting at $4 to $6 per month. Go Daddy is also the world's largest domain registrar.
Three of the ten most reliable hosts run their web sites on FreeBSD, three on Windows and two on Linux.
Netcraft measures and makes available the response times of fifty 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 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.
