My question disappeared and reappeared 3 times !?

I posted a question 2 days back and was getting good answers , suddenly it disappeared with no intimation from Y!A team , it reappeared only to disappear after some time. This has happened 3 times. When I tried to access the answer the message indicated this question cannot be accessed at this point of time. Can I contact Y!A help desk ? Can some knowledgeable person tell me what is happening ?
