My Disney Experience is up and operating again...
When I got back in this morning (around 7 a.m.), it had my reservations, but not my fast pass reservations...so I simply redid them (no trouble getting what I wanted at the times I wanted)...
So, be prepared to have to redo FP+ choices! (Don't know about dining--haven't made any of those reservations yet)...
Good luck to all of us...
