Ouch. I seem to have misunderstood how HAProxy handles this particular situation.

Is there a way to have HAProxy keep attempting to reconnect instead of giving up? The idea is that our users should not experience any 503s while we temporarily take down Mongrels.

I suppose I could write a magic backup server that simply slept a little bit and then redirected back to its own URL, but that would be pretty icky.
