When a character is logged out from an instance, the system cannot recognize whether it is a disconnection, an actual user logout, or if it was cleared. Due to this, if a character leaves an instance, the instance will be removed after a certain amount of time has passed. If these instances are not freed up in this manner then other users will not be able to use them. As such, this is why we have no plans to make adjustments to the time allotted in an empty zone when a player has been disconnected or otherwise. So please keep in mind that while it is possible to enter these instanced zones solo, it does not mean it’s a guarantee that you can clear it while solo.
