Starting today at 12:00 UTC, we will run a few Network tests in an attempt to improve performance of the game under load. Since this is specifically to test how certain components in our infrastructure behaves under real conditions, we have to run these tests with enough players online.
Some users may suffer from connectivity issues or lag during the test. If all goes well, we will continue the test with the increasing player numbers towards peak time in the evening.
