When I use traceroute, I often see abbreviations in the hostnames along the route, such as "ge", "so", "ic", "gw", "bb" etc. I can guess "bb" means backbone.
Does anyone know what any these strings abbreviate, or know any other common abbreviations?
The examples you provided makes me think it's not about country codes.
I guess it's just what you thought: ISP network admins using shorcut when naming their servers.
