Debian is a Linux release, which is widespread for desktop computers, yet it's been becoming more popular as a server Operating System during the last couple of years too. It's very dependable and safe, as fixes are released in a couple of days after an issue is discovered. Debian has a vast support community, so when you have any questions or troubles with the OS or with some of the 30,000+ packages it features, you'll be able to contact the developers right away via e-mail using special e-mail lists and receive a response in 15-20 minutes. The Debian community gives you the best level of support possible, since your questions will be handled by exactly the same people that built Debian in the first place, so they have a detailed knowledge of how their system operates. Because the Operating System is 100% free to use and distribute, no license charges will be added to your web hosting fees and you'll be able to change the code files and any additional software which you install without any restrictions, to optimize the software environment for your sites. Furthermore, Debian performs very well on any hardware, because it's light and efficient and doesn't need much memory.
