What you can do, Dieter, is make all the relevant restarts in one go, then factions can request for "time" on the event server, and the restarts can be actively used as and when required.
Suppose that saturdays are reserved for eventing. Some 4-5 hours. You could divide it into two, first two hours SCRA-RHA vs Corsairs, and after that, they can clear off and have the next bunch, say, Order-Keepers, have their fun.
