As you are already aware, the servers were offline due to a technical issue. After investigation, we noticed some unusual activities. In order to preserve the integrity of all accounts of Fiesta Online NA, we decided to proceed with a password reset of all game accounts. This global password reset was done in a preemptive manner.
This means that you will not be able to login to the game right away but first, you will need to change your password on our website (https://fiesta.gamigo.com/us/password_lost). If you encounter any problems to change the password, please contact our support. (https://support.gamigo.com/index.php?/english/Tickets/Submit) After doing so, you will be able to login as usual.
Thank you for your patience and understanding.
Your Fiesta Online team
