Stop in for a cup of coffee

Appointment at a Gov office today...about an hour's drive. Get a call from the scheduler....their IT department is going to shut down all servers at some random point in the day between 7am and 5pm for 2 hours or so.

The drive is on the gov dime...so I'm rolling regardless.
Well, it's a bit past 7AM... What exactly do you need to be there for?
