Just a quick preview...we will be posting a blog post tomorrow morning with an update. Because of the delayed final blog post, we are delaying things by one week. The plan is to do a 1hr brownout on February 8th, followed by a permanent deployment on February 22nd. We realize that no matter how much notice (announced roughly a year ago), there are bound to be some systems that are both incompatible and unknowingly running on production systems. So, the hope is that a 1hr brownout will help to unearth such systems and give folks time to get them updated.
