We're going to be doing some routine maintenance on the OCE platform tomorrow.
Here's what you'll need to know:
On the **21st September**, Sydney time:
* **At 4:00am**, all ranked queues will be taken offline so that all ranked games end in time.
* **At 5:30am**, the OCE servers will go down for maintenance.
* We expect the maintenance to take approximately 3 hours, after which we'll bring the OCE servers online again.
Please keep an eye here, or on the [OCE Service Status](http://status.leagueoflegends.com/#oce) page for any updates.
