We are shutting our data center down for 7 days to repair the HAVAC/Electrical systems. Long story but it needs to be done this way. Since we are a school district and it is summer we are just going to pull the plug on the network and let that summer staff fend for themselves. I have a secondary MX up with a hold and forward.
There are 4 offsite DC's that could be left running, but they will not be able to talk to each other, their connectivity is via the data center. I am thinking shut them down too. Any issues or concerns that come to mind for a week long downtime for AD?
