The tournament test that ran on 5/18 went very well. We saw our highest number of concurrent tournaments to date, and the servers appeared to bear the load well. There were a few minor bugs exposed during this test, which we'll be fixing during tomorrow's game update. We're tentatively planning to run the next Tournaments test on 5/23, depending on how the update goes tomorrow. Keep your eyes peeled for an announcement on the forums and on the game's log in screen.
