Just curious -- its not for the patch (assuming that since the test releams are still up) and second weekend in the row. A lot of raiding takes place at that time so im curious could you delv a little deeper as to why. If it helps your customers arn't idiots and we would understand the reason.
I edited the post clarifying my own misunderstanding. The extended schedule is for a required ISP maintenance, and I apologize for the confusion. We will attempt to provide more indepth information when possible for any future extended maintenance days.
