Nostalrius Begins - Quality wow vanilla realm (1.12)

I got D/C'd from the server, then when I tried to relog in I inputted my password incorrectly a bunch of times. My account is now locked. I've waited 30 minutes, then another and it is still locked.

What is the process for this account prevention, how long does it take to get my account unlocked and if I try to login and it isn't unlocked does the timer reset?

Logging in unsuccessfully too many times leads to a temporary IP ban (You can't login from any account at all) for 15 minutes roughly. After 15 minutes passes, the IP ban expires and you're free to try logging in again, but be careful because it is possible to login unsuccessfully and get temporarily IP banned again. There's no way to "unlock" this temporary ban aside from waiting out the duration.

If you're getting temporarily banned from unsuccessful logins, you're probably better off changing your password on the Nostalrius website.
