Comment 3 for bug 1391784

Although the proprosed branches fix the first problem (fallback for auto-detection failures), that approach is littered throughout the codebase to support the network-splits functionality which landed this cycle.

This specifically breaks the haproxy configuration template, which now uses inbound acls based on network to load balance traffic over matching backends (required to support https certificates).

One approach might be to have a fallback backend, which would be used in the event that no acl matched, restoring in part how the haproxy configurations used to work prior to this release.
