Configuring DNS
I'm just wondering how would this work...
If say I have a site I wish to be around most of the time --- to a point where the only unfortunet time it'd go offline is a meteor the size of Texas crash into USA and wipe out all datacenters down there --- by means of having mutliple shared/reseller/dedicated servers running. How would I configure the DNS? So far, my only cule was to use third party software such as EveryDNS or EasyDNS to do www1.site www2.site etc. and have a hosting account for www.site to send traffic to different www's. This method will not work when the www.site host goes down, so is there a way to make it so that regardless of each host's status, the website stays online?

IE:
www.mysite.com = some host /w a php script to redirect to known online sites (the next few sites)
www1.mysite.com = some host in Dallas
www2.mysite.com = some DS in Texas
www3.mysite.com = some reseller in Seattle
etc.
How'd I make it so if www.mysite.com's ISP dies, my site is still accessable?
