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 This error typically appears if a timeout error occurs when Fastly cache servers attempt to fetch content from your origins. It can also be due to a variety of transient n
