One of our projects started giving an error this morning like this:
The remote server returned an error: (503) Server Unavailable.

After investigated the stack trace, it seems that the error was  
caused while the application was parsing a template in XML format.  
After the line of DOCTYPE was commented out, the application came  
back running. Here is the original DOCTYPE:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Is there a limit on the number of requests for the DTD file? Is it  
because our application have exceeded the limit, which caused the error?


Thanks,

Jeffrey Zheng
