There is sad news in the WoW community today. The longtime, invaluable auction house resource The Undermine Journal will be closing its doors at the end of July. The Journal cites ballooning server hosting costs as the culprit, and they just can't keep up. Since 2010, The Undermine Journal has been the place to go if you wanted to stay on top of auction house pricing--particularly for comparisons across different servers. The loss of this site is huge blow WoW players as a whole, but particularly for those who make a dedicated hobby out of playing the auction house.
There does remain some hope for The Journal's future, however. If they can find a new server host, it's possible that a revamped Undermine Journal will make an appearance in time for Warlords of Draenor. However, in their news announcement, they caution that if the expansion's launch comes and goes without The Undermine Journal's reappearance, it will likely be gone for good. They will do their best to keep a webpage in place in order to deliver updates on the situation.
From those of us at WoW Insider, we'd like to thank Erorus, the creator behind The Undermine Journal, for all his hard work and dedication to maintaining such a wonderful resource. We hope The Undermine Journal's absence is just a hiatus, but either way, we'll see you at Realm Pop.
