I've got this request about 10 years ago, I wanted to implement a server option called "expect-down", then some users suggested that it could also be convenient to have a "start-down" option which would not mark the servers up by default and which would automatically imply this. And in the end, nothing was done. I think that now that we have the ability to keep the servers state upon reload, these features might be obsolete. Upon reload, you keep the previous state and there's no alert. I'm not certain it's that convenient in the case of a new server being deployed though. Willy
