Patch 2.3.2 on the Public Test Realm of MMORPG World of Warcraft has really been enjoyable for Blizzard's developers and most especially to players.

Several changes were implemented to the character classes as well as their respective professions. However, it seems that the fun will be over sooner than expected as a maintenance has to be performed by Blizzard.

Quality Assurance team member Hortus explained further on the official WoW forums:

We are taking down the PTR realms early to do extended hardware maintenance today. They will not be returning. This will conclude the 2.3.2 PTR phase.

Thank you all for participating in the 2.3.2 PTR, we hope to see you all again in future phases.
