Our move to the new servers is imminent - you may find that you have to log in after the move. Please be sure that you know your password and have a working email address in your CC account so that if you have to log in again you can do so without a problem.
The new servers are at a new IP address, so you may see a bit of confusion as different web servers take differing amounts of time to update their information. (It's sort of like getting a new phone number, but some phone directories take longer to update than others.) Generally, within 24 hours most of this sorts itself out.
If you are experiencing login weirdness after the move, check this thread for more info on cookies:

Our new servers will be more powerful and we'll also have redundancy built-in in case one of them fails.
