Debian is a Linux release, which is widespread for desktop computers, yet it has been becoming more popular as a server Operating System during the last few years as well. It is very dependable and safe, since fixes are released in just a few days after a problem is discovered. Debian has a large support community, so when you have any questions or issues with the OS or with any of the 30,000+ packages it includes, you're able to contact the developers immediately through electronic mail using special mailing lists and receive a reply in 15-20 min. The Debian community supplies the best level of support possible, as all your questions will be handled by exactly the same people that created Debian in the first place, so they have a detailed knowledge of how their system works. Since the Operating System is absolutely free to use and distribute, no license costs will be included with your website hosting fees and you can customize the program code files and any additional software that you install without any restrictions, in order to optimize the software environment for your web sites. Furthermore, Debian performs very well on any kind of hardware, because it's light and fast and doesn't require a lot of memory.
