We will be performing scheduled maintenance on Diablo III starting tomorrow (6/6) at 5:00 a.m. PDT in order to deploy patch 1.0.2b. We anticipate that maintenance will conclude and that all services will be available at approximately 11:00 a.m. PDT. Patch notes are available below.
Important: Please note that you will not be prompted to download patch 1.0.2b until the patch is live in your home region. If you are logging in from a European or Asian client, you will need to wait for this patch to release in that region before it can be installed. Additionally, if your home region is the Americas, you will be unable to log into Europe or Asia using Global Play after patch 1.0.2b is live until those regions have also patched.
For reference, here are the scheduled maintenance times for each region:
The Americas: 5:00 a.m. PDT to 11:00 a.m. PDT
Asia: 8:00 p.m. PDT to 2:00 a.m. PDT
Europe: 1:00 p.m. PDT to 7:00 p.m. PDT
Please note that these times are subject to change. For time zone assistance, please visit:

General

o Once sold, damaged items will be repaired automatically when moved from the purchasing player's Completed tab to their stash
o Please note that unsold damage items will not be automatically repaired when returned to the seller's stash
