My site said it's suspended???

I don’t understand. I was on my site 2 days ago and everything was fine. Now, when I went there today, ir said it’s suspended: https://eatstopeatrevealed.net/cgi-sys/suspendedpage.cgi. How does this happen? I host the site on my own domain. I don’t understand why this happened, what happened to cause this and how this could happen. Can someone please help me? Thank you.
