UK will give sovereignty of Chagos Islands to Mauritius - https://news.ycombinator.com/item?id=41729325 - Oct 2024 (282 comments)

.io will cease to exist as a ccTLD, but it doesn't mean it can't exist as commercial TLD like .app, considering its widespread use. I think eventually it will be auctioned off.

IANA has documentation that outlines what happens in the retirement of a country code top level domain here: https://www.iana.org/help/cctld-retirement

tl;dr, if it happens, there will be a 5 year retirement period. We have quite a while to deal with this it seems. This isn't a nothing-sandwich, but pretty close (unless your company is something .io)

Im confused by this speculation as the .io TLD isnt owned by that country and it isnt disappearing...
