Hi Per, I actually tried using saintmode for this problem but one point that I found tricky is that saintmode (as far as i can tell from docs) can only be set on beresp. If the backend is up, that's great because I can check a non-200 status in vcl_fetch() and set. But in the case of all backends being down, vcl_fetch() doesn't even get invoked and there isn't any other routine and object in the routine's execution context (that I know of) where I can set saintmode and restart.
