Since our inception about one year ago BB-Hosting has used only Debian servers in our hosting operations. We chose Debian because of its ability to work on inexpensive off-the-shelf hardware and lack of licensing fees, we have continued to be impressed with its reliability, flexibility, scalability and last but not least security!
We now have three Debian servers serving hundreds of web sites and e-mail accounts and we've never been disappointed. At the moment we run Debian Sarge on all our servers. The system administrator is pleased with how smoothly the transition is thanks to the well thought out design of all Debian releases. Debian Linux and its package system is a class of its own!
