What happened?

Even I don't know, still tracing back why it happened exactly. Suddenly our server hosting company shutdown our server without any notification and they did not respond to my emails or ticket and they changed our name servers; you guys may have seen some nasty pages being opened at that time and so we don't have time to wait for their reply. So we decided to move our server to a new location and moved to a new one with our backup data, I do hope that it will not happen again.
