Basically something has gone wrong, but the server can not be more specific about the error condition in its response to http://www.checkupdown.com/status/E500.html the client. In addition to the 500 error notified back to the client, the Web server should generate some kind of internal error log which gives more details of what went wrong.

Correcting the error may require recoding program logic for the Web server software, which could take some time. 500 errors in the HTTP cycle Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server: Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs). Open an IP socket connection to that IP address. Write an HTTP data stream through that socket. Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information. This error occurs in the final step above when the client receives an HTTP status code that it recognises as '500'.
