The server downtime will start at 6 a.m. Pacific Standard Time (or at 9 a.m. Eastern Standard Time ).

During the downtime, NCsoft will update the game to version 16.20080122.9T3, which is currently in testing on the Training Room Test Server. NCsoft anticipates that it will last for up to two hours.

In the meantime, if you'd like to see the list of changes that NCsoft has lined up for both City of Heroes and City of Villains, feel free to either visit the current Training Room Patch Notes courtesy of the link below.

Alternatively, you may also check out the live patch notes once the update is completed.
