During a recent meeting within the Systems and Infrastructure Area we were discussing the practice of regular Sunday morning downtime. We decided to revise our practices given the increased reliance and visibility of our various systems. We are going to remain using the same time period, Sundays from 8AM-10AM. However in the short term we will communicate all planned activities for the weekend ahead to LIS by Thursday at 5PM. In the near future,  we will also have a webpage to list this planned work which we can use to help identify potential conflicts.  We also plan to make targeted announcements to the potentially affected groups in some sort of automated fashion and perhaps also develop an opt-in listserv to allow anyone who cares to keep track of such announcements. We think this greater transparency will allow us all to be more aware of and hopefully minimize possible disruptions.
