Rackspace Continues as Most Reliable Hosting Company

Rackspace is the most reliable hosting company, followed closely by managed hosting company Datapipe and Katarre, a colocation and dedicated hosting provider, according to a fall of 2006 study by Netcraft.

Rackspace, a managed hosting provider based in San Antonio, Texas, , has been a mainstay in reliability rankings since tracking of hosting company performance in 2003. This is the fifth time this year that Rackspace has been the most reliable hoster, compared to six times in 2005. The home page for the web site did not have a measurable outage from March 2004 through November 2005, when it experienced three minutes of downtime.

Eight of the 10 most reliable hosters run their sites on Linux with the two remaining having Unknown OS.

Netcraft measures and makes available the response times of 50 leading hosting providers' sites. The performance measurements are made at 15 minute intervals from separate points around the Internet, and averages are calculated over the immediately preceding 24 hour period.

Netcraft says from a customer's point of view, the percentage of failed requests is more pertinent than outages on the hosting companie's own sites, as this gives a pointer to reliability of routing, and this is why they choose to rank by fewest failed requests, rather than shortest periods of outage.

The importance of monitoring your server access logs We recently had a client come to us with random performance problems on their site.  The site is a low traffic brochure site on a shared hosting account.  Most of the time the site performs reasonably well.  However, there are mysterious times where the site slows down to a crawl. This reached a critical point Friday afternoon and their hosting provider shut down the site for using too many server resources.
