"We regret to inform you that over the course of the past 6 months our server stability has declined due to hardware and networking issues. Please be advised we will be addressing these issues towards the end of November 2012. Once a solid date has been set, you will be notified at least 3 days in advance of the change-over. Your server's downtime should be minimal."
This was the notification I received from my hosting company, minus a few other details that you guys don't need to know.
