Does anyone know what this mean? In analytics? @barchard?

Does this mean Chillidog was down for me those times? I’ve been getting this for the last few days.

Hi, no status is at status.chillidoghosting.com

An internal server error is typically a php error. The server wasn’t able to process some php to generate the page.

Greg, thanks, but what causes it and is it something I need to fix? I’ve never seen it before this week, and there seems to be nothing wrong with viewing those pages now.
