Debian is a Linux distribution, that's widespread for desktop computers, but it's been becoming more popular as a server Operating System during the last few years too. It's very dependable and safe, as fixes are released in a couple of 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 features, you are able to contact the developers straight away through electronic mail using special e-mail lists and receive a response in 15-20 min. The Debian community offers the top level of support possible, because all of your questions will be handled by the very same people that created Debian in the first place, so they have a thorough knowledge of how their own system works. Because the Operating System is absolutely free to use and distribute, no license charges will be added to your web hosting fees and you'll be able to modify the program code files and any other software that you install without restrictions, in order to optimize the software environment for your Internet sites. Furthermore, Debian performs very well on any kind of hardware, as it is light and fast and does not require much memory.
