I have four websites with Hostgator having the same problem as of 3 days ago. Ive tried to upload videos and animated gifs and anything over about 10mb just gets stuck in “crunching” and never loads. I spent 3 hours with HostGator and they attempted to put the blame on all the excuses you stated above none of which were the cause. They have since escalated it and are looking into it for me , its very likely a problem they caused as we all have had the same issues begging at the same time.
