On July 11, 2012, starting at 23:30 PDT, ranked queues will be disabled in preparation for the 1.62 patch. At 01:00 PDT, the servers will be shut down. As this time, all games currently in progress will end in a draw and stats will not be recorded. We estimate that the battlegrounds will be unavailable for approximately 4 hours.
The upcoming changes in the patch are:
• Fixed several bugs with invites
