DreamHost Web Hosting, USA

Since our inception over five years ago DreamHost has used entirely Debian servers in our shared hosting operations. Although we initially chose it 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, security, and scalability as we've grown. We now have over 150 Debian servers serving 50,000 web sites and hundreds of thousands of email accounts and we've never been disappointed. We are in the process of upgrading all our servers to "woody" and our system admins are pleased with how smoothly the transition is thanks to the well thought out design of all Debian releases. Our business would not be possible without Debian Linux!
