Realm Maintenance

North America

All scheduled maintenance will be performed on a Tuesday with a schedule that begins at 5 AM and ends at 11 AM PST (-8 GMT). This will allow Blizzard the window of time they need to perform the necessary maintenance tasks to their infrastructure as part of their continued efforts in improving realm stability and performance.

Europe

As a reminder, a weekly technical maintenance is scheduled on all Realms every Wednesday morning. Blizzard try to keep the downtime due to this weekly maintenance in the time frame starting from 4:00 am until 10:00 am (GMT). If a patch is applied during maintenance, then the window will be from 2:00 am until 10:00 am Paris Time.

Realm Types

PvE - On a Player vs Environment realm, you will never be attacked by other players if you want to be, except if you enter an enemy capital or a Battleground.

PvP - On a Player vs. Player realm, you can be attacked by other players everywhere at any time, except in friendly (green) territories and in dungeons (instances). PvP Guide.

RP - On a Role-Playing realm, you should act and speak as your character should in the World of Warcraft setting.
