We will be rebooting any/all windows servers 1-2 times over the weekend for routine maintenance.
Win1 updates are going now, and IIS is down with that.
Win1 is nearing done(iis going up and down with that), win2 is starting soon.
Win1 and Win2 are done, win1 had an update hang and fail, which is why it took a bit longer, and actually may need another reboot tomorrow night to resolve.
Win3 is updating and iis going up/down for that.
Win3 is doing well, but a bit more iis up/down, Win4 is rebooting now.
Forgot to update, but all the reboots that will happening coming 6 hours are done now.
