It’s notable that this June 19 stress test is a test of launch conditions for one entire region’s hardware. To make this test as helpful as possible we need to focus on only including the people of that region. This single region test allows us to better focus on any existing problems that need to be resolved and is an important pre-requisite to complete before multi-region testing.
In the next stress test, in July, with our single-region test complete, our plan is to test multiple regions under launch conditions, and this will include EU test realms.
