Performance improved for us at 5:44 PM EST yesterday, however we received this statement from NS support later in the evening: Our infrastructure teams understand the cause of the performance problems and have a plan to address them via several urgent maintenance events. Due to the nature of the problem, the resolution needs to be rolled out in several phases over the next few days. We will let you know as this effort progresses and as the resolution timeline becomes clearer. Rest assured that this is being worked on as a top priority emergency by our engineering teams.
