today, i need check my site from host-tracker but i get this message: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator to inform of the time the error occurred and of anything you might have done that may have caused the error.

Heh, it kept telling me that my site was down, when it wasn't. It gave me a fright, until I found out that I couldn't even access hostracker. Glad they got it fixed.
