The Auction House on live servers is experiencing some performance issues right now and Blizzard said they’re aware of the issue and will have more details for us soon.
We’re aware of and working on diagnosing and solving issues that are affecting the performance of the Auction House in WoW. At this time, the Auction House is up, but is experiencing degraded response times.
We’ll let you know as soon as we have updates on the situation.
Thank you!
