If you set up your DNS elsewhere - and there's lots of free options available like everydns.net.. Then you could have it changed at the registrar in advance, with a low TTL on the records. If you did that, you could limit your downtime to a matter of minutes (or the amount of time it takes you to fix any "accidents" qwest makes). The other thing is, I recall they removed the 24h transition time in changing your DNS records at the registrar. It's really quick now (not sure I can give an estimate, but not more than a couple hours). Of course you still have to make sure your TTLs are low. Dan
