Lol, I had the same experience with the relief of being able to submit the game after the deadline. I had put off submitting it until about thirty minutes before the deadline (which was a mistake I won't repeat!) and I thought my internet just wasn't working at first. I was so upset until I realized that it was just the website, and I was so happy when I saw that the deadline got extended to account for it. Nice to know I wasn't the only one that felt the stress :)
