Website uptime strategies?
I need to develop a variety of websites that will be very high bandwidth and I'm looking for a good hosting solution. (5-10TB/mo). Uptime is extremely important - I've used Media Temple in the past, and though uptime was good, it wasn't 100%. Should I look into multiple hosts, if so how does the DNS work if one host is down?
BTW, is there any reason to use one hosting registrar over another. I've been using GoDaddy for most of my new registrations, but have also used Network Solutions.
Dedicated sounds good. My primary concern is uptime - so if my dedicated box has an internet outage/crash/etc - I'd like to ensure that the traffic is routed to a backup server automagically. My guess is this is done somehow with my registrar/dns host but I'm not sure.
