If the page has been deleted from the server or it is not currently available you can try to get an achived copy. If you used a link from a search engine, you might be able to get some information by using the "cached" option.

You can also try viewing the site or page from an archive such as the WaybackMachine.

Most archives and cached versions only retains the site text. Graphics and other media objects are linked to the orignal site and may or may not be available.

You might notify the webmaster about the issue. Include the error number and the address (URL) where the error occurred along with any other relevant details.

Many sites use an email address in the form webmaster@sitename.com where you replace sitename.com with the web sites address (don't include a www). Keep in mind with the amount of spam, they may use a different address and/or it might get ignored. Check the websites' contact information to get reliable contact information.

  Official Explanation  
     
 
  technical details

The appConcurrentRequestLimit property is set to a value that is lower than the current number of concurrent requests. IIS 7.0 does not allow more concurrent requests than the value of the appConcurrentRequestLimit property.

(From Microsoft - The HTTP status codes in IIS 7.0)

  Notes  
     
  "503.2 - Concurrent request limit exceeded" is only supported by Microsoft IIS (Internet Information Services) web server version 7 and later.

The five hundred series of errors indicate something is wrong at the server and it is unable to complete the action.
