There is no server uat02 currently in our inventory:

There is a uat01, which, according to our records, is currently allocated to @maurya for “OpenMRS Reference Application 2.2 Testing”. Interestingly, the alias uat-platform was assigned to this host.
It would seem that you would prefer to remove the uat-platform.openmrs.org alias and instead have uat-refapp. Is that correct?
