Interviewed for APS, reference check completed - total silence

I applied for, was interviewed and subsequently moved to reference checks for a job with the Department of Agg.

Since referee submitted their referal which was submitted to the panel for review. I've had complete radio silence. I tried reaching out to the person who performed the ref check, they've been reassigned. I reached out to the person who booked my interview, no response.

Should I give up and just assume I was unsuccessful? Is this just normal APS hiring bureaucracy?
