Our next public mass test will happen on our test server Buckingham on Thursday, November 29, at 17:00 UTC (= EVE-time). We will test further improvements to client performance and bug fixes for our next expansion EVE Online: Retribution.
The testing should last 30-45 minutes. All participants will receive two million skillpoints on our test servers.
Please refer to this thread for more information about how you participate in the test, and this EVElopedia article for more information on mass testing.
