There is a scheduled update to the server operating system for 6:00 am on Wednesday, September 30.
If things go well, the only downtime will be a single server reboot. However, sometimes the server will hang on a reboot of this type and the data center will have to send a technician to put hands on the server. If this happens, there could be downtime ranging from 5 minutes to 2 hours on Wednesday morning.
If there is any significant downtime, updates will be posted on http://status.broncosforums.com.
