Original link: Is the .io top level domain headed for extinction? / ComputerWorld.
The .io TLD which most IT people associate with IO (Input Output) is really "British Indian Ocean Territory" (io = Indian Ocean).
Now the UK is giving the islands to Mauritius as part of its decolonialization. But with a 99 year lease on the Diego Garcia air base that is important for the western air forces.
But without any Indian Ocean territory then the future of the .io TLD is uncertain. My best guess is that they will find a way to keep it. Just pick another meaning for io.
