NEW DREAM NETWORK, LLC is a good and responsible domain hosting provider started back in April, 1997.
The company is employee owned and offers highly competitive hosting packages.
Dreamhost uses Debian Linux as their operating system and offers an easy to navigate hosting administration panel which they've written entirely in Perl; it's quick and secure.
Check them out if you're thinking of obtaining a decent web host at a decent price.
I've been a customer since 2006, and I have no complaints. Support is fast, polite and helpful, and the hosting services do what they're supposed to do, for an agreeable price. I haven't noticed any significant downtimes over the last 3+ years.
