We'll be performing some scheduled maintenance tonight, and to make sure there are no major issues, we'll be disabling Ranked Queues around it. Normal Queues will be enabled and playable during this time.
Here's what you need to know:
* Ranked queues will be offline from **10:30pm**
* Maintenance window is from 11:59pm onwards
* We expect the maintenance to last up to 3 hours.
