There is a request on the Herald that any beta testers make it to a focused stress test tonight, Thursday, November 4th.

[Tonight] at 9:00PM EST, our devs are planning a stress test for Midgard Catacombs zones. If you have a beta account, we ask that you please log on [tonight] night and play in any of the Midgard Catacombs zones. Devs will be monitoring behind the scenes to observe zone performance. There is no level limit for this test. Thank you for your participation!

There is also word that more beta invites have been sent out over the last few days. Check your inboxes to see if you're in!
