dv8 and James,
Our account activation is _instant_
It does not matter if it is 3am on Saturday or 2pm on Thursday, if your payment goes through without a problem, our database sends you your information that you'll need to get started.
After you change your DNS, it can take anywhere from 24-72 hours for your domain name to work. Usually it just takes 24. In the meantime, you can upload using the IP number in the account activation email you'll receive. Using the IP will _always_ work no matter how many times you change your DNS.
