The paper mentions that a numeric suffix scheme works fine if "you have a lot of machines and there are no reasons for any human to distinguish between them".

The paper mentions that a numeric suffix scheme works fine if "you have a lot of machines and there are no reasons for any human to distinguish between them". I’d say modern production setup with a ton of configuration managed machines that no one logs into should be named this way. This is more advice for "snowflake servers" and workstations. As for geographic location I had (viewed) a bad experience college when a server in the main server room started DOSing another box in the same room. The culprit was ruled out for a very long while 'cause it’s name claimed that it was all the way across campus - so it couldn’t be the problem. Because of this I’m with the paper on the no geography in names point. Geography in names causes thinking errors in people.
