Description

The feature has been deployed without operational testing on my side : I tested that the new value has been propagated properly. We need to confirm that it results in the desired behavior, i.e. router will now favor non-MSS sites. and adjust the value as needed.
Work with transfer team and Dave on this in the next week.
