We're going to be performing some public testing for Riot starting next week. As you see in the picture below there are different types of tests.
The stress test will only be performed on the NA server
The open test will be performed on both the EU server and the NA server.
More details in the picture below!
We might have to perform the third test if we require more details or information of any sort. If we do, we'll make sure to announce further details about this potential test after finishing performing the first test. We will keep you updated!
