The generic status text associated with a 503 error is error 503 guru meditation "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 res

It happens from time to time and usually restarting the server instance will resolve it. If not you're going to look at the SharePoint Logs. This tool will greatly help with that. Given that it's not showing all the time I would anticipate that you have two web front ends and you will need to perform these checks across both of them. share|improve this answer edited Jul 20 '15 at 10:02 answered Jul 20 '15 at 5:27 Codingo 2,634113883 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

I've got IIS 8 on Windows 8, and I'm trying to set up a little site locally, while doing some development. In IIS I choose Add Site, give a name, points to a location where I have a index.html file (I've tried different locations, latest in http error 503. a c:\inetpub\wwwroot\test -folder) and otherwise use all default settings. However, when I try to browse to localhost I get "HTTP Error 503. The service is unavailable." I've verified the pool is started, and I've given IIS_IUSRS Full Control on the target folder I've search around but not found anything that solved my issue, and there's nothing helpfull in the EventLog or in the C:\Windows\System32\LogFiles\HTTPERR folder Could anyone tell me what's wrong?
