[ Updated ]Server Maintenance: Patch 4.7

5/6 Update: Due to a recently discovered bug, the 4.7 Maintenance has been pushed back 24 hours.

Here's Riot Masima with more info:

"Summoners, 

We have discovered a high impacting bug on the PBE, overnight testing has confirmed the issue is pretty severe and a fix has been identified and is in progress to be implemented.

This does unfortunately mean we are forced to delay the 4.7 deploy by 24 hours."

Good news everyone - Server maintenance for our next patch, Patch 4.7, has been scheduled!

On May 7th 8th at 3:00 AM PST for NA, 4:00 GMT for EUW, and 2:00 GMT  for EUNE, servers will go down in preparation for the upcoming patch.

Here's 2changz with the NA version of the maintenance announcement:

"On 05/7/2014, starting at 01:30 AM PST, ranked queues will be disabled in preparation for patch 4.7. At 03:00 PST, the servers will be shut down and all games currently in progress will end in a draw and stats will not be recorded. We estimate the battlegrounds will be unavailable for 6 hours."

Here's a collection of the patch 4.7 maintenance threads for each server:

NA, EUW, EUNE, BR, TR, LAS, LAN, RU, OCE

I'll keep you updated as more information on what the patch contains and patch notes become available. While the latest PBE content is usually a good indicator of what's to come, please remember that it is tentative and not everything may make it to live.
