Somehow this reads like German to me. Because "rz" is a common abbreviation of RechenZentrum, meaning DataCenter.

So in English it would be like "dcadmin". Maybe they outsourced it to someone doing "gute Deutsche Wertarbeit", or it's a leftover from some agency having had their fun, or smoke&mirrors from whomever for whichever reasons.
