Myself I have not used token ring since early 1995. However, when I visited an R&D site of an international software company in an higly developed country in Europe 2 years ago they had some cabling work ongoing. Somewhat ashamed my host told me: They are replacing their token-ring network. Not sure whether it was a "standard" 16 Mbit/s network. According to Wikipedia some 100 Mbit/s equipment was manufactured just before the whole technolgy disappeared. That would sound still like a usable speed for office use today, but the supply of spare parts might be problematic.
