Just for your knowledge, IIRC EVE Online servers work 23.5 hours a day as well and nobody finds it a drawback.Find anything other to do in these 30 minutes then - play some another game, take a break from the PC for something, etc.
There's a middle way: get hook/console message to players during that time that maintenance works are ongoing and lags/bugs are expected. Or to get hook let those messages out along with other frequent hook messages such as event reminders.
