I come from China，8:00 in the morning, I submit a site problem，After six hours did not respond，I do not know the dreamhost whether 24 hours service，I use a dedicated server，Processing time for this problem but I was not satisfied。
My site is：500 Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, email@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
I view the log：File does not exist and Premature end of script headers ，But I do not know where the problem lies，Is good, from yesterday on this issue。
So far，My site has more than a dozen hours can not be accessed。I sent the e-mail as soon as possible。I am very anxious。
