If you host multiple websites on your managed dedicated server we do advise to use CloudLinux OS, All CloudLinux innovations, such as CageFS, aim to improve security and stability on servers. So where other operating systems will allow entire servers full of customers to go down, CloudLinux stays stable by isolating the impact to the offending tenant.
We Keep your sites secure, Ksplice Uptrack lets us apply 100% of the important kernel security updates released by our Linux vendor without rebooting. Giving you more Up Time and Security.
kSplice is optional but recommended on our Budget Servers, and is included standard at our Enterprise servers.
Our current default version is the PHP 5.3.x branch at this moment, but we can configure other versions on request, please note that with CloudLinux you also will be able to choose per account which PHP version it should use so if you have some latency scripts running PHP 5.2.x or some cutting edge PHP 5.5.x scripts with CloudLinux you will be able to run them all on one server with the PHP Selector tool.
