Early today (9:30am EST/New York/-5GMT) attempting to launch Diablo III keeps you in a loop saying you will begin to download a patch and the game client restarts but says game up-to-date.

The patch is not yet on the servers for download if this behavior is happening. Sit tight, and try again every 20 minutes until the patch files are available. These are the patch notes posted yesterday at the official forums.

We will be performing scheduled maintenance on Diablo III starting tomorrow (6/12) at 5:00 a.m. PDT in order to deploy patch 1.0.2c. 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 1.0.2c 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 1.0.2c 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: 1:00 p.m. PDT to 4:00 p.m. PDT
Europe: 6:00 p.m. PDT to 12:00 a.m. PDT

Patch Notes

General

  • If the authentication service is busy, the login checkbox will now wait at “Authenticating Credentials” until a player’s login attempt can be processed. As a result, players should no longer encounter Error 37 when logging in.
  • Achievements have been granted to players who previously completed their objectives, but were not correctly awarded completion credit.

Bug Fixes

  • Fixed several crashes which occurred when clicking on player-generated item links in the game client
