Debugging [JA] 日本語 Common 503 errors Varnish, the software that runs on the Fastly CDN, will sometimes return standardized 503 responses due to various issues that can occur when attempting to fetch data from your origin servers. 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 network issues that might cause a read to fail (e.g., router failovers, packet loss) or an origin overload. Benchmarking your backend response times. Many outside factors cause backends response times to vary. Repeated, consistent Backend Read Errors frequently can be prevented by changing your backend timeout settings in the Fastly application. Start by running the following command to estimate response time for benchmarking purposes: curl -s -w "%{time_total}\n" -o /dev/null http://example.com/path/to/file Increasing
