Change subject: Temporarily split the mobile cluster in old and new
......................................................................
Temporarily split the mobile cluster in old and new
The new machines use a much higher chash weight, and would
otherwise get the vast majority of requests on an empty cache.
This lets us split the traffic between old/new with PyBal.
