Typo in the Service Status report for Patch 4.18
"On 09/10/2014, starting at 01:30 PDT, ranked queues will be disabled in preparation for patch 4.18. At 03:00 PDT, 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."
It's 10/8/14, in other words October 8th, 2014 as of the time this post was made. That date says the patch would begin on September 10th, 2014. That's 28 days ago.
Reset your clocks, Rioters.
