I called the 800# and the customer service rep was very polite but did not give me any more info than was on the website. I told her I need to find my name check status and was able to get her to transfer me to an IO. The IO was quite terse but took down my A#, receipt #, service center and parents names etc. and then stonewalled saying my case was within the published processing times. However before brushing me off she said she could not find my case and later quoted the Portland DO processing times. So perhaps my case had moved to the Portland office ???
I got an infopass appointment for the next day. (Note: Based on my observations, it might be easy to get an infopass appointment for the next day instead of 2 weeks out if you try around 4:30pm. That is when I think the next days cancellations or unfilled appointments get posted.)
Unfortunately, that day only one IO was (wo)manning all the customer counters and was visibly agitated about it and kept making announcements to everybody to be patient. When I got my turn about an hour and half late I asked about my status and she took the receipt notice and returned saying that all my checks including fingerprint, name, background etc. were clear but there were more than 6400 applicants in the queue and she had no idea when I would get an interview notice.
I didn't push her any further and I am guessing my application is in the Portland DO and it seems like this years filing->oath timeline without hold ups is trending much longer than the last year cases mentioned above.
