[quote]I was wondering if someone can help me to solve this problem ,
Only DH in my experience. But if it any consolation, it is not just you - this problem has been affecting many users for years. Support has said that it occurs when another user makes a web panel update that prangs your shared server. Your site goes down, and though Support claim it should come up again automatically after 2 hours, I have never seen it come up until after reporting the outage to Support.
