Having the name of the computer which retrieved the translation job can be dynamic in a scaled our scenario. The first attempt can be computer 1 and the job isn't ready and after that computer 2 can do the retrieval part.
It can even be more confusion if a translation job is split into multiple jobs and different computers are retrieving different sub jobs in parallel, which computer name should we display?
In the upcoming Sites 9.1 release we are displaying the computer name in the notification tab in case of an exception.
