As part of the migration away from 44.24.240/20, I have move all clients of S3.Haystack to a new subnet (44.25.66.80/28).  All clients active before I started appear reconnected and working with the exception of MonroeECC.  I think Rob may need to take a look at that if it does not connect up again in the near future.  Any static routes in place for subnets behind those clients were updated as well.
