I got mine
I got in.
I was so nervous and trembling I'm wasn't sure I selected the appropriate stream until I saw the receipt. I can't believe I made it.
For future applicants, if it helps, here's what I did: I downloaded a Chrome extension called "Easy Auto Refresh". I set it to refresh two windows, the "maintenance message" page and the OINP page every 10 seconds (started doing this around 7:30) both windows were scaled to fit in 1/4 of my screen while I used 3/4 of my screen for my usual work stuff. I got in without having to wait in the queue.
The system will ask you for your full name, date of birth, email, country of residence, and phone number. I was very nervous and my hands were shaking, but it roughly takes 90 seconds to fill in everything. You'll get an email confirmation right away with your file number.
