So, all the Fall dates were just released this morning. Was trying to get a permit for middle of October, 3 nights. Within seconds everything was gone, I am not even sure how one could have clicked three separate spots in the amount of time they all disappeared. The new system sucks and may mean I won't do another White Rim multi-day trip. It sucked having to stay up till midnight 3 nights running, but at least it meant you could actually, you know, get a trip.
Edit: So one glitch in the system that would have been great to know, is when you click on an available date, the system assumes that is your first night, and everything before that night disappears. So I made the mistake of clicking on the last night of my (hoped for) trip; I was trying to work backwards because of itinerary issues. Then it seemed like everything was taken. When I unclicked that choice (too late, unfortunately) some other dates showed up. So my doom and gloom post may not be entirely correct. I tried to get as much info as possible about the new system, but nobody told me this piece.
