When I visited one of my sites, I got a page with only the bold and big text:
Welcome to Nginx!
It looked like my site was hacked, actually I was pretty sure about it at that moment. I almost wanted to roll out my backup, fortunately it’s back to normal 20 minutes later, then I thought it might be my computer’s problem. After some digging, it turned out to be my ISP’s problem, somehow my ISP treated my site as an invalid domain and displayed their own search engine (evil), but their own site didn’t work, hence the default page from their proxy server.
