Hello all,

We currently have a problem with a deployment of EpiServer on an internal IIS server. The site seem to be running ok but every so often we're seeing a load of 503 errors. Sometimes it's the whole that experiences the issue, other times it's that image etc won't load, and reviewing the inspector you can see 503 are being returned when trying to retreive the media.

I've checked in the application and system logs on the server and there is nothing in there that's indicating a problem. 

The application runs fine locally so I'm convinced it's an IIS config issue. The site is running on IIS 8.5.

Has anyone come accross this before or knows where else I can look to try and debug the errors?

Many Thanks

Chris
