Debian is a Linux release, that is preffered for desktop machines, yet it has been gaining popularity as a server Operating System during the last few years as well. It's really dependable and risk-free, since fixes are released within a few days after a problem is discovered. Debian has a huge support community, so when you have any questions or issues with the OS or with any of the 30,000+ packages it includes, you can contact the developers without delay through electronic mail using special e-mail lists and receive a response within 15-20 min. The Debian community gives you the best level of support possible, since your questions will be handled by the very same people that built Debian in the first place, so they have a detailed knowledge of how their system functions. As the Operating System is 100% free to use and distribute, no license costs will be included with your website hosting fees and you can change the program code files and any additional software that you install with no restrictions, in order to optimize the software environment for your websites. Furthermore, Debian performs very well on any hardware, as it is light and quick and does not require much memory.
