Unable to access housing application (Am i Screwed?)

So I sired to UCI today at 9:42 pm (because I was very indecisive about my school choice), will it take 24 hours for the SIR to process to bring the housing application? Can i still apply to the housing application tomorrow or does it stop at 12:00am tonight?

If you can’t get in, contact the housing office and explain your situation.
