November 1st - 30th 2005
Hostway is the most reliable hosting company site this month, marking the third time this year that it has been on top of the performance rankings, having shared the top spot in May and September. This month also was the first time since March that a single host stood alone as most reliable.
Hostway’s showing was the bright spot in a rough month for hosting reliability. Of the 50 hosting companies whose web sites we monitor, seven had outages exceeding two hours, and another 10 had measureable downtime. That included a brief (3-minute) outage for managed hosting provider Rackspace, which has led the reliability rankings six times in 2005 and had gone more than 20 straight months without a measurable outage. An outage at Go Daddy was attributed to a denial of service attack.
Three Linux sites are found in the top 10 this month, three on FreeBSD, two on Windows and one on Solaris.
Netcraft measures and makes available the response times of fifty leading hosting providers’ sites. The performance measurements are made at fifteen minute intervals from seven 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.
