I see you didn't get a response.... That's probably because all of us here are users just like you. We have no way of knowing why your site may be down.
What you want to do if this continues is to get in touch with GoDaddy support as close to the time it happens as possible. Only GoDaddy tech support can then look at the server and help determine what the issue may be.
Hope you get things worked out... 😉
