I would suggest warning us before closing the site for some reason.
Something similar to this notification:
You can only submit 5 question during the following 3 days because you are only allowed to ask 50 questions in a 30 day period.
I've asked a question about the problem and I would say Sorry for the tone there.
Actually I was disappointed because I had wanted to ask an urgent question and suddenly I got the
Oops & Sorry message.
