I for me think that you should send out the meeroos @ an other time than 8pm or 9pm. I noticed that @ this time are only few ppls where online in the group. This number of users are not enough to make a stresstest for the server. It would be better if you choose a time when europe, US and Japanese ppls are online because if the server failed with this test all what will come after this will be crap.You don't need to work @ other things before the server is working 100% well with minimum 2500 users at the same time because you will get many many problems in future. A in batch delivery is no answer!
