Good news everyone - Server maintenance for our next patch, Patch 4.15, has been scheduled!
On August 27th at 3:00 AM PDT for NA, 5:00 GMT for EUW and 02:00 GMT for EUNE, servers will go down for maintenance and the 4.15 patch will be applied.
Here's NA version of the Network Operations maintenance announcement:
"Server Maintenance: Patch 4.14 On 08/13/2014, starting at 1:30 AM PST, ranked queues will be disabled in preparation for patch 4.14. At 3:00 AM 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 4.15 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

"Em 27/08/2014, com início às 04:30 do horário de Brasília, as filas ranqueadas serão desativadas em preparação para a atualização 4.15. Às 06:00 do horário de Brasília os servidores serão desligados, todas as partidas em andamento serão encerradas como empate e suas estatísticas não serão gravadas. Estimamos que os campos de batalha ficarão indisponíveis por 6 horas."
