error. 503 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 '503'.

The generic status text associated with a 503 error is "Service Unavailable." It can mean a wide variety of things. The most common reasons this generic text appears include: The origin server generated a 503 error and Fastly passed it through as is. The origin returned a 503 error without a response header, so Fastly used the default response. The status line of the HTTP response from the origin was not parseable. VCL code was run that used the "error" statement without an appropriate response status (e.g., error 503 instead of error 503 "_broken thing_"). The following list provides the most common non-generic, standardized 503 responses and basic explanations for each. WARNING: If you are seeing 503 errors, do not purge all cached content. Purge all overrides stale-if-error and increases the requests to your origin server, which could result in additional 503 errors. 503 Backend Read Error Th

Typically, this can be due to a temporary overloading or maintenance of the server. "This overloading is normally resolved after a period of time (when resources become available again) or once another thread has been released by IIS (or what ever web-server application you are running)Some servers in this state may also simply refuse the socket connection, in which case a different error may be generated because the socket creation timed out.Good programmers / IT people, will create a custom page that is used to show a friendly message to the user that the site is undergoing maintenance.

That is there are 1000 or more queued requests to your website.This could happen (assuming there are no faults in your app) if there are long running tasks and as a result the Request queue is backed up.Depending on how the application pool has been set up you may see this kind of thing.
