As per any SOE website you try to go to:

Beginning at 11:30 p.m. PDT on Monday, September 24th, all SOE services will be unavailable so that we can perform significant upgrades to our authentication and account management systems.

Currently we expect this maintenance to take approximately 14 hours. But, as first indicated, it could extend to as long as 24 hours . Customer service, chat and support will also be unavailable at this time. Phone support will still be accessible. This website will be updated throughout the day as to the progress of the maintenance.

We apologize for this interruption, however when service is resumed we hope to provide you with an enhanced user experience to manage your accounts at Station.com.

Basically, if things go well, everything should be back to normal at 4:30PM EST. If all hell breaks loose expect things to be up, by the latest, 2:30AM EST.

In the meantime keep checking back for the launch of EQ2 WarCry's Rise of Kunark Section!
