[~brandon.williams] thanks for running, I only ran with PAID, so guess there is
some issue with FREE?

> When we are decommissioning we first set LEAVING, then LEFT, then disable
> networking; timeouts start to follow at this last stage. LEFT nodes should
> not be seen as part of the ring, but that may not be seen before the network
> is disabled. To better mitigate timeouts we should set severity as part of
> decom during the LEAVING phase; by setting severity reads should deprioritize
> traffic to this node.
> Remote DC writes do not leverage proximity or severity and instead use random
> for its select, writes may still timeout even though we know the node is
> leaving, and severity is set… to work in this model we should update remote
> DC writes to deprioritize nodes with severity set
